I was finally able to get around this problem with help from the following website: https://towardsdatascience.com/how-to-install-openai-gym-in-a-windows-environment-338969e24d30.
There were basically 3 things I had to do: 1) install Microsoft Visual C++ Build Tools, 2) install this specific verion of Atari https://github.com/Kojoley/atari-py.git, 3) Install Xming. Good luck to all Windows users :) This took me around 3 days to figure out.
I have tried to make it work with python 3.8 and 3.9 on Windows 10. Installing Python 3.7 and using it as the Python Interpreter on PyCharm resolved the issue. I have searched for the missing file while having 3.8 + version of Python and it did not exist at all. Atari-py is supported only for Python 3.7 (https://github.com/openai/atari-py) so having a higher version of that would not work. It is a bad idea to download files from unlicensed places so I advise you to install the supported version of Python (3.5, 3.6, and 3.7). Even though gym can work on 3.9 the atari version will not. I did not need anything else installed (although I may have Microsoft Visual C++ Build Tools, but I deff did not need Xming), just import gym 0.18.0, pyglet 1.5.0, atari -py 0.2.6
Welcome to SO. If you trace the exception trace you see that a shared object loading function is called in ctypes' init.py file aliased as dlopen. On Windows, this correponds to WINAPI's LoadLibrary method. LoadLibrary is trying to load ale_c.dll. ALE is 'arcade learning environment'.
Search your computer for ale_c.dll or libale_c.dll
If you have ale_c.dll (most likely you are on Windows), refer to this answer to see how DLL's loaded with ctypes are basically LoadLibrary calls as I mentioned. It mentions all the stuff about DLL loading order etc. but, if you need a quick way around this, copy your dll under system32 folder.
I had similar issue with Atari-Pacman. It is resolved by downloading atari_py-1.2.1-cp37-cp37m-win_amd64 which is for 64-bit Python 3.7, and installing it by using pip.

I am trying to build an exe file for the GUI that I created using python POyqt5. After completing the process, I try to launch the UI and I get the following error:

I have openpyxl installed and I have also got it imported in my python script. Still, this error remains. Any leads on solving this will be appreciated.
Thanks!
Assuming you are creating the .exe with pyinstaller, try:
pyinstaller YOUR_FILE.py --hidden-import openpyxl.cell._writer
It lets pyinstaller know that openpyxl.cell._writer must be imported. It seems like this module import is done in a "hidden" way in your Python script. Therefore, it is not visible for pyinstaller and must be mentioned explicitly.
downgrade openpyxl to version 3.0.9 will also help. it works for me.
pip unistall openpyxl
pip install openpyxl=3.0.9
I just installed Python 3.7 and Fabric.
It works perfectly on my laptop, but not on my desktop.

I also tried to uninstall/reinstall fabric, but it's still failing.
Do you have any idea why I cannot import fabric.api ?
Update :
I also created a virtual environment :
py -3 -m venv env
code .
Selected Python interpreter "venv" in Visual Studio code then :
python -m pip install fabric
But i'm still facing the same error :-/
Well after few research I finally found a workaround by using fabric3 (a fork of Fabric, compatible python 3).
pip uninstall fabric
pip install fabric3
Link : https://pypi.org/project/Fabric3/
I see you have already installed fabric 2.4.0 which is great! Since you are using the fabric 2.4.0 you can't use from fabric.api import taks. fabric.api could be used if you use fabric1xx
If you want to import connection and task from fabric2.4.0 you have to do it like this
from fabric import Connection as connection, task
#task
def deploy(ctx):
with connection(host=host, user=user) as c:
c.run('ls -la')
Note: fabric 3 is not an official fork. I advise you to use fabric2.4.0

Ive been trying to fix this for a whole day now, if anyone could help me/ point me in the right direction that would be greatly appericiated.
edit:
Also, since i've reinstalled some things to try and fix the problem. the file wont start and gives this error:

Try the fix in Exception: Cannot find PyQt5 plugin directories when using Pyinstaller despite PyQt5 not even being used. In short:
pip intall PyQt5
Note that, strangely enough, conda install PyQt5 may not fix the problem.
I encountered the same problem and saw another suggestion: make the missing directory (C:/qt5b/qt_1524647842210/_h_env/Library/plugins in your case) and copy the two files pyqt5.dll and pyqt5qmlplugin.dll (presumably somewhere in c:\Users[name]\AppData\Local\conda\conda\envs) to the directory.
I did not try it since I fixed the problem with pip install PyQt5. You may want to give it a try.
I am using Python 3.6.3 with ANACONDA3 and Spyder as IDE. Pyinstaller 3.4.
Trying to generate an exe file with Pyinstaller, I had two kinds of errors:
"AttributeError: 'str' object has no attribute 'items' ". This was resolved by
updating each module imported in the Python script, with :
pip install --upgrade <module_name>
"Cannot find existing PyQt5 plugin directories" :this was the next error. As
mentioned by cong yu in his previous post, I fixed this problem by running
pip install PyQt5
Do not forget to upgrade setuptools to the latest version as well
The process delivered an exe file which I have not yet tested.
But at least, I got Pyinstaller reaching the end without failing in error.
Hope this could be helpful
And, by the way, Happy New Year :)
Edit:
I have tested the standalone .exe produced by py2exe
The program is running and get to the end without errors.
But the problem is that xlsx is no more running, because no Excel
files are created. These files are based on pandas dataframes.
My hint is that pandas module, which is the main core of the program,
seems to be altered. I noticed that the dataframes used were truncated,
through the control lines edited in the Ipython console in Spyder.
I think that my best alternative is to reinstall Anaconda3.
So be careful, upgrading the modules used in the program you want as
standalone with py2exe. It seems that upgrading pandas module was a
mistake.
I am sorry, if I gave a bad advice in my main post, but upgrading was the
best way to run py2exe. Be careful with the upgrade of pandas.
Try uninstalling Anaconda. There have been issues in the past. If not you can try py2exe that is fairly decent too.
I installed the latest version of PyInstaller, then this exception of "Cannot find existing PyQt5 plugin directories" is addressed.
You can install the latest version of PyInstaller through the following command:
pip install https://github.com/pyinstaller/pyinstaller/tarball/develop

I checked in the site-packages folder and there was no wx._xml.pyd like there was wx._xrc.pyd. Could this be the reason and how can I fix it ?
As you seem to use Python 3.4 therefore you can only use wxPython Phoenix.
Looking into the last snapshot build wheel from end of October 2016 there is actually a _xml.pyd there, so maybe you have a bonkers wxPython installation?

See the error message above.
Is there possibly an unknown dependency that I'm missing?
Downloading the source tarball and executing python setup.py install produces the exact same output.
Edit: Added the full stack trace for running the installer.
So apparently the python.org version of Python3 is different from the ActiveState version of Python3. (You should file a bug to someone (I'm not sure to whom))
The fix I have (I'm not sure of all the repercussions)
Download:
http://pypi.python.org/packages/source/d/distribute/distribute-0.6.12.tar.gz#md5=5a52e961f8d8799d243fe8220f9d760e
and then extracting it and modify:
distribute-0.6.12\setuptools\sandbox.py:165
from:
except ImportError:
to
except (ImportError, AttributeError):
that will silence the error and allow you to run:
python setup.py install
It took me awhile to find a package from http://pypi.python.org/pypi?:action=browse&c=533&show=all that would actually install on either version of Python3. "files" was the first package, and since it installed I am pretty sure that easy_install is working for both copies of Python3.
...hope it works! (That's all I can help you with)
this is a bug with Distribute http://bitbucket.org/tarek/distribute/issue/151 ... it should be fixed by next release (0.6.13). It is only reproducible with PyWin32 installed; and ActivePython comes bundled with PyWin32.
