I'm trying to install pybrain on python 3.2. It says here: https://github.com/pybrain/pybrain/pull/85 that it should work. However it does not for me.
I tried:
$export PYTHONPATH=$PYTHONPATH:'/home/luis/Documents/pybrain/'https://github.com/pybrain/pybrain/pull/85
which works well for python 2.7.
Did somebody get it to work?
After hours of "what the hell?!"s I installed it.
First the installer suggested is not updated for Python3 so I installed Distribute. With that installed I was able to use python setup.py install in the directory where I unrared pybrain. It gave a ton of errors. So I found this article (god bless google translate) and used 2to3 on pybrain directory. After I tried to install it again it gave an error on from string import split so I edited the file and removed that line (it is not needed really) and tried yet another time. This time no errors occurred and I was able to import pybrain without any problems. The same problem with the from string import split occurs in utilities.py again, so edit that line too.
I used 2to3 to turn examples to python3 too. benchmarkplots.py seems to work.
Update:
pybrain now supports python3
Here's how to install if you run into trouble
pip install https://github.com/pybrain/pybrain/archive/0.3.3.zip
Or just grab latest github pybrain release.

I am building a desktop app using Python and PySimpleGUI. So far, everything works just fine. Whilst I was working at the project, I realized I need to find a way to get the duration of some mp3 files and to display it in a certain way. I discovered mutagen module that is supposed to help me in this sense, I installed, and here the problem arise:
It throws me ModuleNotFoundError: No module named 'mutagen'.
Seeing this, I started to look for the problem, but I couldn't not understand why my interpretor did not find the module even though I Installed it CORRECTLY. (as PyCharm told me)
I have tried the following:
I am using a local virtual environment that has installed the dependecies for the project(and some extra) and I uninstalled and installed the package 3-4 times
I deleted the local virtual environment and I created another one. I installed the packages again and same issue.
I installed a random module (scipy) and I tried to import it somewhere in the project and it thrown me same error, but this time for scipy module
My guess is that I did not configured properly my interpreter, but to be honest, I have no idea what I am doing wrong, because I followed the same steps I've been using for creating a venv with its according interpreter and for other projects, it worked just fine.
Further details:
Using python3.9 base .exe
I installed the packages in two ways: one using the pycharm IDE, and one by running pip3 install mutagen
You may be using a different pip that is not the one that affects the Python you are using. Instead of using
pip install mutagen
Consider using pip as a module of the Python you are using:
python -m pip install mutagen
This way you'll be sure you are working on the same Python.
If you want to continue using plain pip, try which python and which pip to make sure they are referencing the same environment.
I am having the error while running jupyter notebook. Error replication:
python --version
Python 3.7.9
python
import win32api
The error was: ImportError: DLL load failed
After doing a some stackoverflow, I got to know that there are 2 dll files missing namely: pythoncom37.dll and pywintypes37.dll
I also got to know that I can run this post command: pywin32_postinstall.py in the Scripts folder. I ran this script. Restarted my pc. I manually download these two dll and copied it to my system32. After manually downloading, I started to have a different type of error: ImportError: DLL load failed: %1 is not a valid Win32 application
I used anaconda and ran my jupyter notebook which was my main aim but can you please make me aware as what is going wrong?
I've run into this recently, but with a different version of the DLLs. What solved it for me was using a different version of pywin32.
My solution (conda env, python 3.8.5):
pip install pywin32==300
or try 225, 227, 228. The latest pywin32 (301 as of this post) seems to be having dll search issues (I wouldn't be surprised if whatever version you were using is also having dll search issues). 301 was released after your issue started, but you may have a similar problem nonetheless.
There is currently an issue on pywin32 DLL loading failing: https://github.com/mhammond/pywin32/issues/1709
Factors involved (in my experience) include your PATH variable (if you're using conda). I haven't tested it myself, but I'd be curious to see if this issue occurs without conda. This issue stops happening for me if the first dlls found are those for 301. In my case, that means putting them in my C:\Windows\System32 folder (yeah I'm on Windows; joy).
So a possible solution #2 would be to run the pywin32 post install script which should be located under your venv/Scripts/pywin32_postinstall.py
To try that solution, open an ADMIN command prompt (very important that it's admin), navigate to your venv, and run:
ppython.exe Scripts\pywin32_postinstall.py --install
You shouldn't HAVE to do this, but if you just need a one-off solution and it works, great!
pip install --upgrade pywin32 ==225 worked for me. Tried version 300 and was unsuccessful.

python3 env is not used when I update my Mac to the latest version. How can I solve it?
This worked for me with the same issue.
Check if you have multiple Python3.x versions installed. In my case I had Python3.6 and Python3.9 installed. brew uninstall python3 did not remove Python3.6 completely.
I was able to call Python3.9 from Terminal by explicitly running python3.9 instead of python3, which led me to believe the issue was caused by ambiguity in which Python3.x resource was to be used.
Manually deleted /Library/Frameworks/Python.framework/Versions/3.6 resulted in Python3 running as expected.
hint:
It may be sufficient to remove /Library/Frameworks/Python.framework/Versions/3.6 from your PATH environment variable.
Check in the location:
/usr/bin/python3
If you can invoke python3 interpreter from this location without any issues, copy this to
/usr/local/bin/python3
I upgraded to macOS Big Sur and had faced the same issue. I was not able to open Python interpreter from terminal and the Python version inside Library/Frameworks/Python.framework/Versions/3.6 was also being pointed to Python2.7.
Later, I found python3 in location /usr/bin/python3 working fine for me. I also tried creating a symlink for python3 to the above path but didn't work.
That's becuase you have installed both python 3.6 from system library & python3.9 from other source like brew and there are something wrong with the python in lower version. Please manually delete the python within /Library/Frameworks. sudo rm -rf /Library/Frameworks/Python.framework/Versions/3.6 this command works for me.
I encountered this same problem on Step 1 of PyCharm's Create a Django project documentation.
I had previously set up Python on my Mac following these instructions. Can't promise this solution will work for everyone, but maybe if someone's Python was set up similar to mine the following solution that worked for me might help you...
Open Terminal
which python3
Copy the directory given to you... (For me it was /Users/foo/.pyenv/bar/python3)
When creating your new Django project in PyCharm (Professional Edition), set your base directory to the one received from which python3
Create your project
My case
Deleted Xcode (Maybe some folders are accidentally deleted like /Library/Frameworks/...
Also installed Python with anaconda.
My solution
Reinstall Xcode
Followed this to remove anaconda then everything works fine
I want pylint to use python3 for linting in Visual Studio code on Mac (which has both python 2.7 standard and python 3.6).
I've tried changing the path to the python interpreter as per How can I debug Python3 code in Visual Studio Code, to no avail. I keep getting python2 errors instead of python3 errors.
See example code for the problem.
Is there a way I can get pylint to recognize python3 errors?
Pick a xx.py in Visual Studio Coce(VSC)
In Status Bar Tap Python 2.7.10 like the [img1]
Choose python 3.x like [img2]
Command+Q quit VSC, then open VSC again
I finally got it working by installing python3 pylint from the console.
sudo python3 -m pip install -U pylint
The simple solution is to just change the first line of the file /home/user_name/.local/bin/pylint from #!/usr/bin/python2 to #!/usr/bin/python3
If you want more, you can rename this file to pylint2 and have a copy pylint3 where you change the first line to #!/usr/bin/python3.
Now to use pylint3 from command line you just need to type pylint3 instead of pylint.. also change the directory of pylinter in vscode to /home/user_name/.local/bin/pylint3
explanation
Ok this might be very late and the answer might not be the optimum, but I had the same issue.
By default the path to pylint is /home/user_name/.local/bin/pylint that is a simple python script working as the entry point to pylint.. even after installing pylint using pip3 this file is not changed and keeps directing to use python2 and therefore the packages installed by pip2 for python2.
So either have separate entry points for each pylint version, or modify this one manually to use the pylint package installed for python3.
Ok, I am using python 3.4.3 and I think I downloaded the right file but when I go to python shell, it says No module named 'cx_Freeze'
I know there are plenty of questions like this but none of them helped. There was one I found using my exact same problem and version but even that did not work. I do not know what to do. I have put the file in the same place, I think anyways, as python is and I tried putting it on my desktop but still does not work. Any ideas?
faced a similar problem (Python 3.4 32-bit, on Windows 7 64-bit). After installation of cx_freeze, three files appeared in c:\Python34\Scripts:
cxfreeze
cxfreeze-postinstall
cxfreeze-quickstart
These files have no file extensions, but appear to be Python scripts. When you run python.exe cxfreeze-postinstall from the command prompt, two batch files are being created in the Python scripts directory:
cxfreeze.bat
cxfreeze-quickstart.bat
From that moment on, you should be able to run cx_freeze.
cx_freeze was installed using the provided win32 installer (cx_Freeze-4.3.3.win32-py3.4.exe). Installing it using pip gave exactly the same result.
Ok, I figured it out. So this is for all the future people have the same problem as I am. First, download pip. Then open a python shell and import pip. This is to make sure the download of pip was successful. Then go to the cx_Freeze website and for python 3.4.3, it will be the last one I think. It will say the version of cx_Freeze and then say the version of python which is 3.4.3 for me. That will download and then go to python shell and import cx_Freeze. It should work. Remember that you have to capitalize the "F" and have the code be exactly like this "cx_Freeze" but without the quotes. That is how I solved this problem with this exact python version.
