FileNotFoundError for jwst data Extraction

[SLimbu30]

Can anyone help me how I can resolve this error? I have followed the instruction given in https://spacetelescope.github.io/jdat_notebooks/install.html
but still seem to have some type of error:
"FileNotFoundError: Unable to fetch schema from non-file URL: http://stsci.edu/schemas/jwst_datamodel/image.schema".

Hi @karatmate, this problem is caused by a mismatch of versions between stcal, jwst, and asdf. Can you please paste here the versions you are using for these three packages?
I am assuming this is the same problem you reported here.

Hello, @camipacifici Thank you very much for helping me resolve this issue, I appreciate it alot. Yes, that is also the problem that I posted. The versions of stcal and asdf are as below:
Name: stcal ; Version: 1.3.0
Name: asdf; Version: 2.14.3
I couldn't use pip install jwst to install the package maybe because I am in windows, but I can attach the problem it shows when I try to use that code. So instead I use GitHub to clone this jwst: https://github.com/spacetelescope/jwst.git

This is the first error code I get:

This is whats written in the end of the error code:

I did try and install visual studio C++ packages but it didn't do any difference. If there's any way I can get it to work, it would be amazing! thank you!

Hi @karatmate, I did not realize you are on a windows machine. Unfortunately, windows is not currently supported for the jwst package (as mentioned on the readme of the jwst github repository).
Any chance you can use a different machine or a linux virtual machine on your windows machine?

Thank you for your response. I used my mac to get the data sorted. I had an error initially which was solved by installing xcode. But regardless thanks for your help.
