Tutorial [WinError 3] The system cannot find the path specified about gluonts

[DaleThomas68]

Thanks so much for the suggestions and your very timely responses! I tried installing the master branch both by downloading the files, changing to the directory, and then using ‘pip install .’ and by pip install git+https://github.com/awslabs/gluon-ts.git. Both errored out for me, and I could not successfully install. So, I manually edited the two files after using pip gluonts in a new environment and also cleared my temp directory to handle the possible caching issue. After all of that, things ran successfully. Thanks again! Here was the error that was reported (I probably made a simple mistake, and I would love to know what it is so I will know in the future if you have time to answer): (gluon_ts) C:\Users\dalet\Desktop\gluon-ts-master\gluon-ts-master>pip install .

This looks like a hand-written path somewhere (the “/tmp” path on Windows means nothing).

Thanks, looking into it.

#77 should have fixed the issue. Until a new release is tagged, you can try out the master branch by cloning the repo and doing

cd gluon-ts
pip install .

and verify that the tutorial notebook works fine (fingers crossed).

Thank you for the super quick assistance! That apparently took care of the initial issue that caused things to error out immediately, and I was now able to get to the end of model training.

That's really weird, because tempfile should now use the right default temporary directory for windows (c:\temp or something like that).

Maybe something got cached? Did you try installing the master branch on a brand new environment?

I think there is a problem in the package build process on Windows. I’ll open a dedicated issue for that.

Good to hear that the fix works though, you will be able to properly get the upgraded package with pip install —upgrade once we release a new version.

hi, Could you please help me in this error:
