Ml-agents: ModuleNotFoundError: No module named 'win32api'

[TrollOfAllTrolls]

So I've tried to run the learn.py program using the following command:
mlagents-learn /config/config_trainer.yaml --train --run-id=test

However, it keeps returning this error:
Traceback (most recent call last):
File "c:users\jpste\anaconda3\envs\ml-agents\librunpy.py", line 193, in _run_module_as_main
"__main__", mod_spec)

from trainer_controller import TrainerController
ModuleNotFoundError: No module named 'trainer_controller'

I followed the instructions as told multiple times, restarting a few instances, yet I keep getting this error. I'm honestly lost as to what I did wrong at this point...

Hi @TrollOfAllTrolls,

Can you let me know what platform you are using, and how you installed the mlagents python package?

[TrollOfAllTrolls]

Oh right, I should have clarified that I'm using windows. I used Anaconda to install the mlagents python package, first creating the ml-agents environment. I then installed all the necessary content from the requirements file in the ml-agents folder

Hi @TrollOfAllTrolls

We have updated our installation process for v0.6, could you try it using the new system and see if the error persists?

[whiteGhost333]

Hello,
Excuse me for jumping in, but, this is wigging me out. I also have an Anaconda, tensorflow installation and I went back to 2017.4.18 which seems the safest. I was working with 2018.2.14 and actually had better luck in that in one shining moment I was able to connect with 3DBall environment but could never get it to repeat the trick.

Here's a python log which has me in a choke hold :
(ml-agents) c:\Users\msi\Downloads\ml-agents>mlagents-learn C:\Users\msi\Downloads\ml-agents\config\trainer_config.yaml --env=3DBall --train

Any pointers or comments would be greatly appreciated.

Thanks!

@whiteGhost333 Which version of the code are you using and which platform are you running this on?

[xiaomaogy]

Oh I was able to reproduce this. You just need to type "pip install pypiwin32" to fix this. I will put a fix for this.

[whiteGhost333]

windows pro 10, 2017.4.18, tensorflow 1.7.1 python 3.6 & ml-agents 0.6.

I'll give the command stream a go.

Below are the results in anaconda. It was apparently the command was successful, but, an even more baffling error occurred...

@whiteGhost333 Can you post a snapshot of the message you see?

[whiteGhost333]

@xiaomaogy It is in the tail end of my last message.

Here is a newer one from my last attempt.

C:\Users\msi was unexpected at this time.

[xiaomaogy]

@whiteGhost333 It seems that the error message you received says your path C:\Users\msi doesn't exist or something similar.

[whiteGhost333]

Not really...

(ml-agents) C:\Users\msi>conda info --envs

This might also be because your "mlagents-learn" command hasn't been installed correctly. Have you done "pip install . " within your ml-agents folder that contains setup.py? Has the ml-agents 0.6 python package been installed successfully?

[whiteGhost333]

I was planning on doing a reinstall in order to compare the results. I
have do a couple of refreshes already...one more can't hurt. one item of
difference is I used 'pip install -e .'

pip install -e . is the same, it just uses the local version of the code instead of the v0.6 one.

[whiteGhost333]

Voila !!!..I was able to connect to the 3Dball scene build...this is after
running pip install pypiwin32, of course. See below. One item which
surprised me was that I did not get the build results
I expected , i.e. the learning brains are in scene but not the build. I
must have missed something there?

I guess you didn't check the learning brain as external, or something else.

[whiteGhost333]

ah, yes you must be referring the control check box. will give it a go.
thanks for the help.

I ran into this as well on Windows 10 64bit using ml-agents 0.6.
I would suggest adding the "pip install pypiwin32" command to Installation-Windows.md.

[whiteGhost333]

I'd second the motion.

Also ran into the same error and the pip install pypiwin32 command fixed it for me. Feels good to finally have it running after uninstalling/reinstalling multiple times combing over the windows install guide profusely.

Thanks!

[xiaomaogy]

I will add the pypiwin32 dependency to the installation this or next week.

[Cbunz]

So I was getting:

ModuleNotFoundError: No module named 'win32api'

So I used the command pip install pypiwin32, which installed properly. When I try after installing, I get this error:

Import Error: DLL load failed: The specified module could not be found.

[gregaton]

Did you follow the Windows installation guide and added the environment variables? (the folders are enough)
It's important to use the right python and tensorflow version.

[LSDemian]

@Cbunz I had the same issue
Here's what helped for me https://github.com/michaelgundlach/pyspeech/issues/23#issuecomment-280915608

[xiaomaogy]

Since this bug is fixed, I will close the issue. Feel free to open if you want to discuss more.

[pepeto]

I had the same issue and it was fixed after running pip install pypiwin32
