Issue compiling on Ubuntu about retro-learning-environment

[nadavbh12]

This is due to an issue with Genesis-Plus-Gx ekeeke/Genesis-Plus-GX/issues/125 .
If it will take too long to fix, I'll write a workaround.

[nadavbh12]

@timgriffin, My last commit should fix this issue.
Let me know if the problem persists.

Still having trouble compiling on Ubuntu on AWS.

[nadavbh12]

Please copy the make log so I can have a look.

Well it looks like you compiled everything.
Am I missing something?

[jmichaux]

Sorry. I was confused by all of the warnings. I installed the Python interface instead using pip install --user . command. The install seemed successful. However, I got the following error when I tried to import RLEInterface

In [1]: from rle_python_interface import RLEInterface

OSError Traceback (most recent call last)

Note I think I have found librle_c.so here: /home/ubuntu/.local/lib/python3.5/site-packages/rle_python_interface/librle_c.so

[nadavbh12]

Looks like while you've installed the library in /home/ubuntu/.local/lib/python3.5/site-packages/rle_python_interface/ the imported python file rle_python_interface is located in /home/ubuntu/Retro-Learning-Environment/rle_python_interface.
This is why he can't find the shared library (so) file.

You should open Python from a different dir such that the imported rle_python_interface.py file is the installed on.
By the way, you can also install RLE using `pip install rle-python-interface'. I'll add that to the doc...

[jmichaux]

Thanks, I tried from a different directory and I got this error:

In [1]: from rle_python_interface import RLEInterface

ImportError Traceback (most recent call last)
in ()
----> 1 from rle_python_interface import RLEInterface

ImportError: cannot import name 'RLEInterface'

[nadavbh12]

These errors are usually caused due to circular dependencies or PYTHONPATH issues.
I'd recommend to uninstall and the reinstall the package. If that doesn't work.
Look into your setup or google to see what may be causing this. I don't think it is related to the package.

[nadavbh12]

@jmichaux - is everything working now?
Regarding the seed issue, check this out.

[jmichaux]

Yes, I think everything is working now. Thanks a lot!

[nadavbh12]

Great.
