SRW import fails in OASYS windows installation

[jureyherrera]

Hello, I have and issue that appeared suddenly, when launching OASYS1.2 in windows 10, it fails to import SRW with the following message:

Error importing 'orangecontrib.srw.menu.ow_srw_tools_menu'
Traceback (most recent call last):

I have the same problem in two different PCs (Win10), and the same happened to another OASYS windows user.

Thank you in advance for your attention.

Kind regards, J

Your environment looks messed up. The location for the installed libraries is wrong, and it should be ...\Miniconda3...\site-packages

it means that it is installing the libraries in the site-packages of another python, where SRW is not supposed to run. We distribute it precompiled for the specific version of Miniconda we use to install Oasys. I believe you should change the PATH somehow, to allow Miniconda finding the right location to install the libraries via pip. Then I believe it must be done in the script that start Oasys. I'll dig into it and then it would be better to reinstall.

Yes, you are right, OASYS should use the env in Miniconda3, but I don't know when OASYS started to look for this other environment. BTW, I have tried to uninstall everything and reinstall, but same issue persist.

Reinstalling won't work until the issue of conflicting environments is fixed

Ok, here what we found (for public record):

• uninstall OASYS1-SRW from Oasys (Add-ons form)

• open a Miniconda3 prompt

• type: python -m pip uninstall oasys-srwpy

• reinstall it manually from the prompt, typing: python -m pip install oasys-srwpy (--upgrade, optional)

• install OASYS1-SRW from Oasys (Add-ons form)
