Issue in the example code

[khc800]

Hi Amir, In the example code:

# Create the wave object
W = wave.WavePropagator(inpa, src, rec_loc, model_shape,
                        n_well_rec=n_well_rec,
                        components=seisout, chpr=0)

# Call the forward modelling 
d_obs = W.forward_modeling(model, show=False)  # show=True can show the propagation of the wave

When I run the code, I keep receiving this error:

Cell In[6], line 7
      2 W = wave.WavePropagator(inpa, src, rec_loc, model_shape,
      3                         n_well_rec=n_well_rec,
      4                         components=seisout, chpr=0)

Is it exactly this example file that you're using? https://github.com/AmirMardan/PyFWI/blob/main/example/gradient_example.ipynb

Could you please specify your system and the version of pyopencl that you use?

Also, before calling d_obs = W.forward_modeling(model, show=False), please print W.nt and let me know what value you get.

Hello, I have exactly the same problem with the basic example in the documentation. I am running the code in Google Collab. Below is the requested data:

W.nt: 1400
OS: Linux-Ubuntu 22.04.3 LTS
PyOpenCL: 2024.1

Please uninstall the package and install the new version from issue_11 repository. If it works, I will merge this branch to dev and finally main.

So, before loading PyFWI, run these two lines in a cell,

!pip uninstall -y PyFWI
!pip install git+https://github.com/AmirMardan/PyFWI.git@issue_11

It worked for me thank!
