Patch 1.1.2 can be imported well before, but can't import the newest patch. I saw you remove the lib files, but it seems like still try to find it.

Hello, sorry for the delayed reply.

It looks like the path which you show in your FileNotFoundError is missing a \ (PyGeopack__data should be PyGeopack\__data) - if this is the issue, then I have probably messed up the string formatting somehow. It may be something else though.

Can I ask how you installed it? And whether you had a previous version installed before? Some of the older versions can leave files behind when they are installed which could also cause problems...

In the mean time, I shall try and install Windows 11 on a VM and see if I can reproduce it, in case it is a W11-specific problem!

Right, I did some digging, and I found some issues, which I think I fixed... It didn't want to compile correctly for me in W11, leading to the same error you appear to have. It does work for me now.

Hopefully these steps should get it working for you:

make sure you have gcc/g++/gfortran/openmp installed (all of these are provided by TDM-GCC)
install the latest version of the DateTimeTools package (DateTimeTools==1.2.1)
install the latest release of PyGeopack (PyGeopack==1.2.3)

Please let me know if this works for you if you get a chance. Cheers!

It works well! Thank you for your continuous work!
