I successfully configured gurobi on centos 7 and it works if I try gurobi_cl on a test.lp file where the test.lp file contains just one line:
Minimize
Now i try to import gurobi from a script that is launched from httpd an I get this error:
From gurobi import *
File"/usr/lib/python2.7/site-packages/gurobipy/init.py" line 1 in
From .gurobi import *
ImportError: libgurobi90.so: cannot open shared object file:
No such file or directory
I am using gurobi9.0.1 and python 3.7 and I don't know why gurobi is calling python 2.7 in the log below.
Could you please help me?
Thanks
Solved the problem. I had to add gurobi_pi.conf under old.so.conf containing the path to my gurobi folder
ldconfig

I am installing Cplex python API into my MacBook. So I followed the tutorial given in YouTube (https://www.youtube.com/watch?v=oINxanpv_2M) and have installed the script & library for Cplex using the Terminal instructions:
cd /Users/my_name/IBM_CPLEX/CPLEX_Studio1210/python
python3 setup.py install
this part works alright with everything installed, just a note from the Terminal at the beginning saying 'python wrapper is not found'.
Then I tested an existing Cplex problem using
cd IBM_CPLEX/CPLEX_Studio1210/python/examples/mp/modeling
python3 production.py
, which returned:
Model: production
- number of variables: 6
- binary=0, integer=0, continuous=6
- number of constraints: 5
- linear=5
- parameters: defaults
Traceback (most recent call last):
File "production.py", line 101, in <module>
if model.solve():
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/docplex/mp/model.py", line 4152, in solve
return self.fatal("CPLEX runtime not found: please install CPLEX or solve this model on DOcplexcloud")
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/docplex/mp/model.py", line 884, in fatal
self._error_handler.fatal(msg, args)
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/docplex/mp/error_handler.py", line 210, in fatal
raise DOcplexException(resolved_message)
docplex.mp.utils.DOcplexException: CPLEX runtime not found: please install CPLEX or solve this model on DOcplexcloud
So my initial guess is that my python 3 has been installed in another directory under the Library folder, and a path will be needed to link the Cplex engine to the python solver (if correct). Inside the YouTube tutorial, a PATH is actually provided, so in my case it's written as:
PATH="/Library/Frameworks/Python.framework/Versions/3.8/bin:${PATH}"
export PATH
export PYTHONPATH=/Users/my_name/IBM_CPLEX/CPLEX_Studio1210/cplex/python/3.7/x86-64_osx
I have actually installed Cplex python API into a Windows PC previously. The path-adding step was done by visiting:
Control Panel -> System and Security -> System -> Advanced system settings -> Environment Variables. Visit (https://www.youtube.com/watch?v=hqGZzRh00y0) for specific further steps.
However, I tried quite a lot of ways adding this path to my Mac, and so far I've used those to write the above path but none worked:
nano .bash_profile.pysave
nano .bash_profile
sudo nano /etc/paths
That's where I got stuck. Any help and comment would be highly appreciated. I am new to Mac Terminal. Anaconda is also installed in my Mac if that's helpful.
Sorry for the massive details - was trying to put down everything in case there was something unnoticed that I have done wrong. Thanks.
Added:
A small issue in the process above was that my Python was actually 3.8. So after adding the path export PYTHONPATH=/Users/my_name/IBM_CPLEX/CPLEX_Studio1210/cplex/python/3.7/x86-64_osx and running a cplex example, a message popped up inside the Terminal:
Exception: CPLEX 12.10.0.0 is not compatible with this version of Python.
Need to download an older 3.7 version then did the $ python3.7 setup.py install process again after changing my directory to IBM_CPLEX/CPLEX_Studio1210/python.
Some similar issues about Python version have been discussed in the post: CPLEX and Python 3.7.
I am trying to do the following in Python 3.7.1 on Windows
import sqlite3
but I get the following error message
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "c:\programdata\anaconda3\lib\sqlite3\__init__.py", line 23, in <module>

ImportError: DLL load failed: The specified module could not be found.
I have searched for a solution to the problem for quite a while now to no avail. I have also successfully run pip install pysqlite3 on the Anaconda prompt, but the import still fails. What do?
I got this working on windows by downloading: the sqlite3 dll (find your system version)
And placing it into the folder: C:\Users\YOURUSER\Anaconda3\DLLs
(Depending on how you installed Anaconda, this may have to be placed into
the following folder: C:\ProgramData\Anaconda3\DLLs)
According to #alireza-taghdisian, you can locate the exact path of
your conda environments (where you need to copy the sqlite3 dll) by typing:
conda info --envs on your anaconda prompt.
Locate the sqlite3.dll file. In my case it was in following folder
C:\Users\Admin\anaconda3\Library\bin
where C:\Users\Admin\anaconda3 is the folder where Anaconda was installed
Add this to PATH in environment variables, and it should work then.
Try copying the sqlite3.dll from the
C:\Users\YOURUSER\anaconda3\Library\bin
folder to
C:\Users\YOURUSER\Anaconda3\DLLs
Please check https://github.com/jupyter/notebook/issues/4332
I added anaconda root/Library/bin to my PATH and now it works!
Add CONDA_DLL_SEARCH_MODIFICATION_ENABLE=1 to your environment variables.
before executing the program, enter conda activate in your shell.
I had tried all above solutions But for me and my system I got to know that
I downloaded Python in C:\Python27 hence there is dll folder in python C:\Python27\DLLs
I installed Sqlite3.dll in my above dll folder
May be this solution will help you because it completely depends on where do you install your python
Happy coding :)
I put the sqlite3.dll in the path folder of my Python venv and still wont work. I suspected it is a path problem.
(In my case: E:\Virtual_Env\mini_zinc\env\Scripts)
I found in my case I messed up installation in a virtual evn, somehow using an anaconda python kernel within a Python venv.
I reinstall the Python Venv and check the python version after installed Env is correct (not the Anaconda python), then proceed with Jupyter Notebook (or Juyterlab) and works fine.
I was able to resolve this issue by putting sqlite3.dll file in the C:\Users<USERID>\AppData\Local\conda\conda\envs<ENV NAME>\DLLs.
Download sqlite3.dll file from https://www.sqlite.org/download.html
or copy it from C:\ProgramData\Anaconda3\DLLs\
I found the #elgsantos useful. But for those who are new to Python and Conda like me, I would like to add a little bit of details.
1- I use miniconda3 for creating new environment.
2- interestingly, I got two installation path on my computer for conda: the first one (the obvious) is located on "C:\Users\taghdisian\miniconda3". The second one is on "C:\Users\taghdisian\AppData\Local\r-miniconda". The latter is the primary path that you need to copy your sqlite3 files into the envs folder. I copy them in the "C:\Users\taghdisian\AppData\Local\r-miniconda\envs\sdr3.9\DLLs" in which the sdr3.9 is one of my virtual Condo environment.
you can locate the exact path of your conda environments (where you need to copy sqlite3) by typing the conda info --envs on your anaconda prompt.
I hope this help.
got the same error while loading the jupyter notebook from other conda prompt than "base" environment.

I'm playing with the MapR Sandbox and would like to import some data in MapR stream using python. But I'm having an importing issue and I dont know why. I followed instructions from MApR website (see reference at the end of this post) and looked everywhere for a clue, but know I don't really know what else I can do. I tried with python 2.7 and python 3.6.
File "producer.py", line 1, in <module>
from mapr_streams_python import Producer
ModuleNotFoundError: No module named 'mapr_streams_python'
I have installed it globally like doc is telling me to do, the file is located in /usr/lib64/python2.7/site-packages for python 2 /usr/lib64/python3.6/site-packages for python 3
Someone has an idea?
Thank you
References
https://mapr.com/docs/60/AdvancedInstallation/InstallingStreamsPYClient.html
https://mapr.com/docs/52/MapR_Streams/MapRStreamsPythonExample.html
I noticed that the folder for the module was incorrectly named in the folder that it was installed at. After getting to the directory with the modules (/usr/lib64/python3.6/site-packages), just run this command:
cp -R mapr_streams_python-0.11.0-py3.6.egg-info/ mapr_streams_python
You should then be able to import the package in python.
Am trying to install utilities module for both python and anaconda environment.I have python 3 in my Mac.Here is the error I get.
pip install utilities
Could not find a version that satisfies the requirement utilities (from versions: )
No matching distribution found for utilities
Please help :(
If you are trying the ML example from here, then please copy the utilities.py from chapter 2 in your python 3 in Lib directory and you will be able to use the utility module.
Please try the below:
pip install data-utilities
You can find more on the Python Package Index - data-utilities website.
There is no module named utilities in Python,I believe you have encountered importing a file called utilities.py by the line import utilities. Showing the full source code might help. Additionally, check the gitgub repo of your source code for a file called utilities.py and copy it to your execution folder. If you are talking about python-utils, check this link.
Python Utilities contains many standard utility modules to solve common problems. They are :
File System -- os, os.path, shutil
Running External Processes -- commands
Exceptions
HTTP -- urllib and urlparse
Check This link
If this doesn't solve your issue, try installing the utilities-package using :
pip install utilities-package
I am using python 3.4 on windows 7. In order to open a doc file I am using this code:
import sys
import win32com.client as win32
word = win32.Dispatch("Word.Application")
word.Visible = 0
word.Documents.Open("MyDocument")
doc = word.ActiveDocument
I'M not sure why is this error popping up every time:
ImportError: no module named win32api
Although I have installed pywin32 from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pywin32
and I have also checked the path from where I am importing. I have tried reinstalling pywin32 as well but that doesn't remove the error.
Try to install pywin32 from here :
http://sourceforge.net/projects/pywin32/files/pywin32/
depends on you operation system and the python version that you are using. Normally 32bit version should works on both 32 and 64 bit OS.
EDIT: moved to https://github.com/mhammond/pywin32/releases
This is a bug in the library itself, probably they used a different python implementation for creating this.
What they are trying to import is the site-packages\win32\win32api.pyd file, but the win32 folder is not in the path that python searches in, but site-packages is.
Try to replace the import win32api (inside win32com\__init__.py) to from win32 import win32api
I encountered the same error yestoday with Python 3.6.1 on Windows 7, and resolved it by "pip install pypiwin32".
Had the same error trying to import win32com.client (using Python 2.7, 64-bit). I agree with TulkinRB, there seem to be path issues, but the fix suggested did not work for me, since I also could not import win32.
Perhaps my fix will also work in Python 3.4.
Eventually, installing the .exe from SourceForge as an administrator (as suggested in Rina Rivera's answer here) allowed me to import win32com.client from IDLE, but not when I executed the script I was originally trying to run.
In the end, I discovered 3 differences in the sys.path that had been extended when I installed as admin and opened IDLE, but were not applied when executing a script. By extending the sys.path in my script, I was able to get rid of the import errors when I executed it:
import sys
sys.path.extend(('C:\\Python27\\lib\\site-packages\\win32', 'C:\\Python27\\lib\\site-packages\\win32\\lib', 'C:\\Python27\\lib\\site-packages\\Pythonwin'))
Finally, if you want more than a temporary fix, the sys.path could be permanently extended by establishing IDLESTARTUP or PYTHONSTARTUP variables (as described here and here).
You can create the __init.py file inside the win32 folder and then go inside the win32com folder and change its __init__.py file, where it is import win32api, change to from win32 import win32api
I ended up debugging and copying and pasting the necessary files into the appropriate folders. It's a work-around until the bug is fixed, but it works.
from https://github.com/mhammond/pywin32/issues/1151#issuecomment-360669440
append the 'pypiwin32_system32' path to your system PATH,
in a script this can be done like:
import os
sitedir='C:/where_ever/'
os.environ["PATH"]+=(';'+os.path.join(sitedir,"pypiwin32_system32"))
...
from powershell
$env:PATH="$PATH;C:\where_ever\pywin32_system32";
python.exe ...
