GemPy is an open-source, Python-based 3-D structural geological modeling software, which allows the implicit (i.e. automatic) creation of complex geological models from interface and orientation data. It also offers support for stochastic modeling to address parameter and model uncertainties.

`pip install gempy[base]` → ModuleNotFoundError: No module named `torch` #900

Closed JoostGevaert closed 5 months ago

JoostGevaert commented 5 months ago

Hi 👋 Amazing that it's now possible to use GemPy without the need for following complicated installation instructions, and that it's now also possible to run GemPy in Google Colabs! When I want to install GemPy with the recommended installation procedure pip install gempy[base], and then try to import GemPy, I get a ModuleNotFoundError: No module named torch, see Error Message below.

To Reproduce Provide detailed steps to reproduce the behavior:

  1. Create a new conda environment with python=3.11
  2. Activate conda environment
  3. pip install gempy[base]
  4. Run Python
  5. Import gempy

Expected behavior Import without issues. This works in Google Colab, because in Google Colab Torch from PyTorch is already installed by default.

Dear @JoostGevaert ,

thanks a lot, great to hear 😄.

The installation problem you describe is indeed a bug - should not be necessary by default. @Leguark mentioned yesterday that it should be fixed today.

Kind regards and happy modeling!

JoostGevaert commented 5 months ago

Thanks for the quick reply, and great news that it'll be fixed soon!

Just encountered the same issue

pip install torch solves the issue until it is fixed in the requirements.

It was a rogue import in the gempy engine. Just pushed a hotfix. Make sure to reinstall gempy_engine (v2024.1.4.1). Thanks for catching this up
