Node error when running Python agent

[jwood803]

After initial installations, when I try to run the node command to run the Python agent, I seem to get this error:

UnhandledPromiseRejectionWarning: Error: EPERM: operation not permitted, unlink 
'C:\Users\jw\Downloads\simple.tar\simple\errorlogs\match_rbTjSvgatNxY\agent_0.log'

Restarted to see if another process had a handle on that location, but I still get the same error.

Node version is 14.17.5
Python version is 3.6.12 :: Anaconda custom (64-bit)

If any other logging is needed, just let me know.

This is likely a quirk of the CLI tool on windows systems. This is usually not a issue though. Did a replay file still generate?

[jwood803]

It didn't. The folder generated in the "errorlogs" folder, but that was also empty.

[StoneT2000]

Is this powershell or command prompt?

[jwood803]

It's happening with both, actually.

[StoneT2000]

Can you try running the command but specify --out=replay.json as an argument? replay.json should pop up in the directory

Full cmd output is here.
The reply.json did get generated, thought I'm not sure if that's the correct one. The two bot from main.py just walk back and forth between two tiles (default main.py).

[StoneT2000]

Yeah that's the default bot. Looks like it's working then. For now ignore the unlink bug

Ran it again in Powershell. It doesn't seem to create the replay, though.

PS C:\Users\jw\Downloads\simple.tar\simple> lux-ai-2021 main.py main.py --out=replay.json

However, it may just be me having this issue, so I'll keep messing around with it to see if I can generate the replay. Thanks for all the advice!

For now, you can stick to using kaggle-environments or use WSL and the CLI tool or use the docker cli tool.

Same behavior here on Windows as well.
I tried running it w/my Mac... It requires sudo but looking at the replays, all commands are empty.
Tried using the Docker image and everything worked. I guess the recommendation should be to just use the Docker image.

Same issue here Win10 tried lots of different things, file permissions, run as admin, different npm versions, clearing npm cache, closing applications, restarting and various combinations of them. Similar issue on latest Ubuntu + node.

[StoneT2000]

And on ubuntu? What's your output when running on ubuntu

On install.

When run as root.

[StoneT2000]

appears to be a different issue @aaronhance. Can you use

sudo npm i -g @lux-ai/2021-challenge@latest

instead?

Seems to work now, despite installation errors https://gist.github.com/aaronhance/1d6485c2944581589fe8b944e7e12576

[StoneT2000]

You can ignore the install errors. They don't mean anything relevant to the engine

Windows 10 python 3.9.5 after lux-ai-2021 main.py main.py --out=replay.json got:

This error is okay @Vadimcg, you can ignore it
