Issue with Web applications with ParaView & trame #7

Open abhishekchitwar opened 1 week ago

abhishekchitwar commented 1 week ago

Trying to understand the parallel post-processing with ParaView and trame as web app. However, facing following issue.

Reference

https://www.kitware.com/exposing-web-application-with-paraview-5-13-is-getting-simpler/
ParaView is using venv: .venv
Traceback (most recent call last):

Using latest nightly build of ParaView and Python 3.10.10

Appreciate guidance in this regard!

jourdain commented 1 week ago

Can you try with the release instead of nightly?

Still issue persists!

Are you using the mpi from ParaView? Also try to pass a full path for the venv as I'm not sure how it get interpreted when processed via mpi.

abhishekchitwar commented 1 week ago

Using following MPI 

mpiexec

mpiexec -n 4 pvbatch --venv D:/Research/trame-app/paraview/.venv -m ptc.apps.sphere

I mean that mpiexec should come from inside C:\Program Files\ParaView 5.13.0\bin.

abhishekchitwar commented 1 week ago

Installed following version ParaView-5.13.0-MPI-Windows-Python3.10-msvc2017-AMD64.msi. I didn't find the mpiexec with mentioned path.

cquammen commented 1 week ago

Installed following version ParaView-5.13.0-MPI-Windows-Python3.10-msvc2017-AMD64.msi. I didn't find the mpiexec with mentioned path.

Indeed, on Windows, mpiexec is installed when you install MS-MPI. It should be in C:\Program Files\Microsoft MPI\Bin.

cquammen commented 1 week ago

I was able to start this example on my Windows machine with ParaView-5.13.0-MPI-Windows-Python3.10-msvc2017-AMD64.msi installed, so it should work.

The fact that you are seeing ParaView is using venv: D:/Research/trame-app/paraview/.venv 4 times suggests that you might be using a version of ParaView for Windows that does NOT support MPI. That message should appear only once. What does your PATH environment variable say? Is there a chance that there is another pvbatch being found?

Another suggestion: let's try without mpiexec for the moment. Can you run pvbatch --venv D:/Research/trame-app/paraview/.venv -m ptc.apps.sphere and see if a non-MPI version runs?

abhishekchitwar commented 1 week ago

Not sure what's going wrong, I have checked the env, only one version is set to path C:\Program Files\ParaView 5.13.0\bin\

jourdain commented 1 week ago

can you try running C:\Program Files\ParaView 5.13.0\bin\pvbatch.exe instead of plain pvbatch?

abhishekchitwar commented 1 week ago

Getting following O/P 

D:\Research\trame-app\paraview_poc>"C:\Program Files\ParaView 5.13.0\bin\pvbatch.exe"

jourdain commented 1 week ago

Just to be clear the full command line should be

mpiexec -n 4  "C:\Program Files\ParaView 5.13.0\bin\pvbatch.exe" --venv "D:/Research/trame-app/paraview/.venv" -m ptc.apps.sphere
abhishekchitwar commented 1 week ago

Sorry! No! I think, need to reinstall it, still same O/P

Just out of curiosity, your venv has been built with Python 3.10?

abhishekchitwar commented 1 week ago

Thank you, @jourdain and @cquammen, for your guidance. I can now run the program as expected. To achieve this, I recreated the virtual environment and only installed the paraview-trame-components module. It appears there was a conflict with other modules I had installed in the virtual environment, which are: but need to check specifically.

Probably vtk was conflicting with ParaView's VTK.
