I am facing a problem with a program i am developing in Python 3.6 under Windows 10.
One particular command generates an unknown error, windows throws a 'program.exe has stopped working' message and the program exits.
The command is a 3d-model loader that is part of another python package (Panda3D). The crash is always associated with this command (and more particularly with a specific dll of the loader) and a particular file that it tries to open.
Since i cannot locate and therefore solve the faults in the dll (probably there is a bug there) i would like to just pass the problematic file and continue to the next one. But since python exits and i do not know the error type, the typical try, except does not work.
So, i would like to know if there is a way to predict this type of behavior in my code and prevent the program from exiting.
Many thanks for any help.
The pop-up "Program.exe has stopped working." can be caused by a variety of things and therefor there is no "one size fits all" type solution. But if you're certain that your problem is cause by a specific line of code you can always try something along the lines of :
try:
loader.loadModel("c/path/to/your/file")
except Exception as e:
print(e.message, e.args)
# your error-handling code here
Make sure the file path that you're giving to loadModel respects the following :
# WRONG:
loader.loadModel("c:\\Program Files\\My Game\\Models\\Model1.egg")
# RIGHT:
loader.loadModel("/c/Program Files/My Game/Models/Model1.egg")

I'm trying to annotate a variable holding the return of a call to asyncio.start_server. The problem is, Pycharm is not able to identify all the methods that the AbstractServer class contains.
Basic example:
import asyncio as a
async def server():
svr: a.AbstractServer = await a.start_server(lambda r, w: None, "127.0.0.1", 5555)
await svr.serve_forever()
This code works (when I use a real callback and connect a client). Pycharm complains though and shows a "weak error" on the await svr.serve_forever() line:
Unresolved attribute reference 'serve_forever' for class 'AbstractServer'
Which is weird because AbstractServer in events.py definitely contains that method:
class AbstractServer:
"""Abstract server returned by create_server()."""
. . .
async def serve_forever(self):
"""Start accepting connections until the coroutine is cancelled.
The server is closed when the coroutine is cancelled.
"""
raise NotImplementedError
. . .
In Pycharm though, when I click the little * in the border next to class AbstractServer to see the stub, this is what it redirects me to (in events.pyi):
class AbstractServer:
sockets: Optional[List[socket]]
def close(self) -> None: ...
#coroutine
def wait_closed(self) -> Generator[Any, None, None]: ...
For some reason, the stub only lists two methods and a property for AbstractServer. So even though the class does have methods like serve_forever, Pycharm seems to only be referencing the incomplete stub.
Does anyone know why Pycharm's stub for this class is incomplete and how it can be fixed? I'd rather not need to add in ignore-comments just to circumvent the type-checker. I tried "Invalidate Caches/Restart", but that didn't seem to do anything.
I'm not sure what the repercussions of this will be, but here's my "fix" in the meantime:
I navigated to C:\Program Files\JetBrains\PyCharm Community Edition 2019.1.3\helpers\typeshed\stdlib\3, which is where the stubs are located
I renamed /3/asyncio to asyncio_BACKUP (essentially deleting it from Pycharm's perspective without actually deleting it). I could have also just renamed the specific events.pyi file inside 3/asyncio/ and left the rest alone.
I restarted IntelliJ (actually I ran "Invalidate Caches/Restart", although I'm not sure if that was necessary)
It's auto-completing fine now. Pycharm seems to have fallen-back to using the events.py instead of using the incomplete events.pyi stub.
I hope someone posts a proper fix. This seems to be fine in the meantime though. Maybe I'll try just reinstalling Pycharm; although that seems like a heavy fix.
Warning
This solution ended up being poor. Pycharm seems to be unable to load ctrl+q documentation for anything without an associated .pyi entry. Now when I try to load documentation, it loads the documentation for asyncio itself. I'm going to rename the folder back to what it was, and selectively re-name events.pyi instead to limit the problems this causes.
I have a very strange problem with the constructor of AptPkg::Cache object in the precise package of libapt-pkg-perl (v. 0.1.25).
The perl script is designed to download a debian package for three different architectures (i386, armel, armhf). For each architecture I do the following:
Configure AptPkg::Config '$_config' with the right parameters and package-lists for the desired architecture.
Create the cache object with AptPkg::Cache->new .
Call the method AptPkg::Cache->policy to create the AptPkg::Policy object.
Call the method AptPkg::Policy->candidate("program-name") .
Download the package for the selected architecture.
This works very well with Ubuntu Lucid, but with Ubuntu Precise I can only download the package for the first architecture defined. For the other two architectures there will be no installation candidate (method AptPkg::Policy->candidate("Package-Name") doesn't return an object).
I tried to build a workaround and I found one solution how the script works for all three architectures, without problems, in precise:
If I create the cache object (with AptPkg::Cache->new) twice in a row it works and the script downloads the debian package for all three architectures:
my $cache = AptPkg::Cache->new;
$cache = AptPkg::Cache->new;
I'm sure that the problem has something to do with the method AptPkg::Cache->new because I checked everything else, what could cause the problem, twice. All config-variables are set correctly and I even get a different Hash for AptPkg::Cache->new for each architecture, but it seems that I am overlooking something important.
I'm not very familiar with perl, so I am asking you guys if someone can explain why the script works with the workaround but not without it. Further it looks quite strange if you have the same line of code twice in your script.
Maybe you hit this bug - https://bugs.launchpad.net/ubuntu/+source/libapt-pkg-perl/+bug/994509
There is a script there to test if you're affected. If it's something else consider submitting a bug report.
edit: Just saw this is 11 months old :/
I am working on an application which uses Boost.Python to embed the Python interpreter. This is used to run user-generated "scripts" which interact with the main program.
Unfortunately, one user is reporting runtime error R6034 when he tries to run a script. The main program starts up fine, but I think the problem may be occurring when python27.dll is loaded.
I am using Visual Studio 2005, Python 2.7, and Boost.Python 1.46.1. The problem occurs only on one user's machine. I've dealt with manifest issues before, and managed to resolve them, but in this case I'm at a bit of a loss.
Has anyone else run into a similar problem? Were you able to solve it? How?
The problem was caused by third-party software that had added itself to the path and installed msvcr90.dll in its program folder. In this case, the problem was caused by Intel's iCLS Client.
Here's how to find the problem in similar situations:
Download Process Explorer here.
Start your application and reproduce runtime error R6034.
Start Process Explorer. In the "View" menu go to "Lower Pane View" and choose "DLLs".
In the top pane, locate your application and click on it. The bottom pane should show a list of DLLS loaded for your application.
Locate "msvcr??.dll" in the list. There should be several. Look for the one that is not in the "winsxs" folder, and make a note of it.
Now, check the path just before your application runs. If it includes the folder you noted in step 5, you've probably found the culprit.
How to fix the problem? You'll have to remove the offending entry from the path before running your program. In my case, I don't need anything else in the path, so I wrote a simple batch file that looks like this:
path=
myprogram.exe
That's it. The batch file simply clears the path before my program runs, so that the conflicting runtime DLL is not found.
This post elaborates on #Micheal Cooper and #frmdstryr and gives a better alternative than my earlier answer.
You can put the following in front of a python script to purge the problematic entries.
import os, re
path = os.environ['PATH'].split(';')
def is_problem(folder):
try:
for item in os.listdir(folder):
if re.match(r'msvcr\d\d\.dll', item):
return True
except:
pass
return False
path = [folder for folder in path if not is_problem(folder)]
os.environ['PATH'] = ';'.join(path)
For the vim with YouCompleteMe case, you can put the following at the top of your vimrc:
python << EOF
import os, re
path = os.environ['PATH'].split(';')
def is_problem(folder):
try:
for item in os.listdir(folder):
if re.match(r'msvcr\d\d\.dll', item):
return True
except:
pass
return False
path = [folder for folder in path if not is_problem(folder)]
os.environ['PATH'] = ';'.join(path)
EOF
A more general solution is:
import os
os.environ['path'] = ";".join(
[path for path in os.environ['path'].split(";")
if "msvcr90.dll" not in map((lambda x:x.lower()), os.listdir(path))])
(I had the same problem with VanDyke SecureCRT)
(This might be better as a comment than a full answer, but my dusty SO acct. doesn't yet have enough rep for that.)
Like the OP I was also using an embedded Python 2.7 and some other native assemblies.
Complicating this nicely was the fact that my application was a med-large .Net solution running on top of 64-Bit IIS Express (VS2013).
I tried Dependency Walker (great program, but too out of date to help with this), and Process Monitor (ProcMon -- which probably did find some hints, but even though I was using filters the problems were buried in thousands of unrelated operations, better filters may have helped).
However, MANY THANKS to Michael Cooper! Your steps and Process Explorer (procexp) got me quickly to a solution that had been dodging me all day.
I can add a couple of notes to Michael's excellent post.
I ignored (i.e. left unchanged) not just the \WinSxS\... folder but also the \System32\... folder.
Ultimately I found msvcr90.dll being pulled in from:
C:\Program Files (x86)\Intel\OpenCL SDK\2.0\bin\x64
Going through my Path I found the above and another, similar directory which seemed to contain 32-bit versions. I removed both of these, restarted and... STILL had the problem.
So, I followed Michael's steps once more, and, discovered another msvcr90.dll was now being loaded from:
C:\Program Files\Intel\iCLS Client\
Going through my Path again, I found the above and an (x86) version of this directory as well. So, I removed both of those, applied the changes, restarted VS2013 and...
No more R6034 Error!
I can't help but feel frustrated with Intel for doing this. I had actually found elsewhere online a tip about removing iCLS Client from the Path. I tried that, but the symptom was the same, so, I thought that wasn't the problem. Sadly iCLS Client and OpenCL SDK were tag-teaming my iisexpress. If I was lucky enough to remove either one, the R6034 error remained. I had to excise both of them in order to cure the problem.
Thanks again to Michael Cooper and everyone else for your help!
Using Michael's answer above, I was able to resolve this without a bat file by adding:
import os
# Remove CLS Client from system path
if os.environ['PATH'].find("iCLS Client")>=0:
os.environ['PATH'] = "".join([it for it in os.environ['PATH'].split(";") if not it.find("iCLS Client")>0])
to the main python file of the application. It just makes sure system path didn't include the paths that were causing the issue before the libraries that loaded the dll's were imported.
Thanks!
This post elaborates on #Micheal Cooper and #frmdstryr.
Once you identified the problematic PATH entries, you can put the following in front of a
python script, assuming here that iCLS Client and CMake are problematic.
import os
for forbidden_substring in ['iCLS Client', 'CMake']:
os.environ['PATH'] = ';'.join([item for item in os.environ['PATH'].split(';')
if not item.lower().find(forbidden_substring.lower()) >= 0])
Concerning the vim with YouCompleteMe case, you can put the following at the top of your vimrc:
python << EOF
import os
for forbidden_substring in ['iCLS Client', 'CMake']:
os.environ['PATH'] = ';'.join([item for item in os.environ['PATH'].split(';')
if not item.lower().find(forbidden_substring.lower()) >= 0])
EOF
If none of these solutions is applicable for you, you can try to remove the problem causing
entries from you PATH manually, but you want to make sure you don't break anything else on your
system that depends on these PATH entries. So, for instance, for CMake you could try to remove
its PATH entry, and only put a symlink (or the like) pointing to the cmake.exe binary into some
other directory that is in your PATH, to make sure cmake is still runnable from anywhere.
Thanks for the solution. I just little modified this sample code as the path variable in my system contains the string "ICLS CLIENT" instead of "iCLS Client"
import os
# print os.environ['PATH']
# Remove CLS Client from system path
if os.environ['PATH'].find("iCLS Client") >= 0 or os.environ['PATH'].find("ICLS CLIENT") >= 0:
os.environ['PATH'] = "".join([it for it in os.environ['PATH'].split(";") if not (it.find("iCLS Client")>0 or it.find("ICLS CLIENT")>0)])
I also had the same problem with embedding Python27.dll from a C-program using the Universal-CRT.
A <PYTHON_ROOT>\msvcr90.dll was the offender. And <PYTHON_ROOT> is off-course in my PATH. AFAICS the only users of msvcr90.dll are the PyWin32 modules
<PYTHON_ROOT>\lib\site-packages\win32\win32*.pyd.
The fix was just move <PYTHON_ROOT>\msvcr90.dll to that directory.
PS. PyWin32 still has this as an issue 7 years later!
In my case the rebuilding of linked libraries and the main project with similar "Runtime execution libraries" project setting helped. Hope that will be usefull for anybody.
In my case, I realised the problem was coming when, after compiling the app into an exe file, I would rename that file. So leaving the original name of the exe file doesn't show the error.
The discussion on this page involves doing things way far advanced above me. (I don't code.) Nevertheless, I ran Process Explorer as the recommended diagnostic. I found that another program uses and needs msvcr90.dll in it's program folder. Not understanding anything else being discussed here, as a wild guess I temporarily moved the dll to a neighboring program folder.
Problem solved. End of Runtime error message.
(I moved the dll back when I was finished with the program generating the error message.)
Thank you all for your help and ideas.
Check any library having user specified path by Process Explorer. It is not necessary must be msvcr??.dll
I solved same problem except I run Python 3. Present solutions not helped because they not indicate unusual paths of msvcr90.dll. I debug code step by step inside till error dialog appears after rows (called when my code was importing PyTables module):
import ctypes
ctypes.cdll.LoadLibrary('libbz2.dll')
Then Process Explorer helps to find path to old libbz2.dll caused the problem (steps 3, 4 of #Micheal Cooper algorithm)
Adding this answer for who is still looking for a solution. ESRI released a patch for this error. Just download the patch from their website (no login required), install it and it will solve the problem. I downloaded the patch for 10.4.1 but there are maybe patches for other versions also.
I have a desktop application developed with wxPython. The applications runs fine under Windows and OSX (same codebase, no platform specific code). Everything works on Linux except drag and drop. I can drag just fine, but DoDragDrop always returns wx.DragCancel. I can however, drag from my application or to another app/desktop which excepts text and DoDragDrop returns wx.DragCopy.
It seems to me like the DropTargets aren't getting called. I've added debug statements to OnData, etc and they are never activated.
Has anyone seen this and know of a workaround?
Found a known issue in wxWidgets that was considered fixed, http://trac.wxwidgets.org/ticket/2763, I am able to recreate this issue on linux. I reopened the ticket.
In the meantime you can swap your StaticBoxSizers or BoxSizers. or...
This works....
parent = DropTargetCtrn.GetParent()
boxes = [x for x in parent.GetChildren() if type(x)==wx.StaticBox]
tmpParent = wx.Panel(parent)
for box in boxes:
box.Reparent(tmpParent)
box.Reparent(parent)
parent.Destroy()
This solution seems to lower the StaticBox in the window hierarchy so it don't interfere with drop events. Note, box.Lower() does not work.
