Exercise #4+5, Part I: No module named 'paraview' #25

Closed lanrikhenge closed 1 year ago

lanrikhenge commented 1 year ago

Hello everyone,

I am working on the exercise #4+5. I started my work with a git pull so everything should be up to date. Most worked fine and I was able to execute everything including the parameter_variation_1d.py-file. In the next step, I am supposed to execute a code snipped in a Jupyter notebook. Therefore, I created a Jupyter notebook in my excercises/-directory. When trying to execute the notebook, I get the following error message:

ModuleNotFoundError Traceback (most recent call last) Cell In [3], line 5 3 import torch as pt 4 import matplotlib.pyplot as plt ----> 5 from flowtorch.data import FOAMDataloader 7 # 8 # adjust the path if necessary 9 # 10 cases = glob("./boundary_layer_1Dvariation/Ub*")

ModuleNotFoundError: No module named 'paraview'

Since the error message tells me that no module named 'paraview' is found, I checked modules of the ml-cfd environment using >>> help('modulues') in Python. The output does not contain paraview.

After a quick research i did not find a way to install paraview using pip. I hope someone can help me to mitigate this problem.

Thank you, Henrik

Hi @lanrikhenge,

this issue has something to do with the current flowtorch version (compare to issue #20). As Andre mentioned in the last lecture, the version of flowtorch currently defined in the requirements.txt is not correct and needs to be reinstalled as described in lecture 4, slide 4.2.

If this doesn't solve the issue, please let me know.

Regards Janis

Hi @JanisGeise,

thank you for your help. I followed the instructions before trying it the first time, but it seems like I didn't do it properly, now it works!

Best regards, Henrik
