Question AttributeError: 'PathDistribution' object has no attribute 'entry_points'

For training the environment on Release 17, I followed these guide:
https://github.com/Unity-Technologies/ml-agents/blob/main/docs/Installation.md
https://github.com/Unity-Technologies/ml-agents/blob/main/docs/Getting-Started.md

But, when I run

mlagents-learn

command, this error happened:

Traceback (most recent call last):

  File "C:\Users\Yuulis\anaconda3\envs\mlagents2\Scripts\mlagents-learn-script.py", line 33, in <module>

    sys.exit(load_entry_point('mlagents', 'console_scripts', 'mlagents-learn')())

  File "C:\Users\Yuulis\anaconda3\envs\mlagents2\Scripts\mlagents-learn-script.py", line 22, in importlib_load_entry_point

    for entry_point in distribution(dist_name).entry_points

AttributeError: 'PathDistribution' object has no attribute 'entry_points'

In fact, the same error happened when I tried on Release 12. At that time, I downloaded https://github.com/Unity-Technologies/ml-agents/tree/release_12_branch instead of https://github.com/Unity-Technologies/ml-agents/tree/release_12_docs and I solved the problem.

But this time, I downloaded https://github.com/Unity-Technologies/ml-agents/tree/release_17_branch , so maybe it doesn't cause problem. Where is the problem?

<My Situation>
・I created a virtual environment "mlagents2" for python 3.6.7 with Anaconda3.
・I downloaded Release 17's branch.
・I ran the following commands in sequence on Anaconda3:

(mlagents2) C:\Users\Yuulis>pip install torch==1.7.1 -f https://download.pytorch.org/whl/torch_stable.html

(mlagents2) C:\Users\Yuulis>cd C:\Users\Yuulis\ML-Agents\ml-agents-release_17_branch

(mlagents2) C:\Users\Yuulis>cd ml-agents-envs 

(mlagents2) C:\Users\Yuulis>pip install -e . 

(mlagents2) C:\Users\Yuulis>cd .. 

(mlagents2) C:\Users\Yuulis>cd ml-agents

(mlagents2) C:\Users\Yuulis>pip install -e .

And I checked these packages installed:
mlagents==0.26.0
mlagents-envs==0.26.0
torch==1.7.1+cu110

 

How can I check "leaking into virtual env"?

 

@christophergoy
The path returned like this:

C:\Users\yuulis\anaconda3\envs\mlagents2\Scripts\mlagents-learn.exe

Is this place correct?

In the case of Release 12, which works fine, like this:

C:\Users\Yuulis\anaconda3\envs\ml-agents\Scripts\mlagents-learn.exe
