@ambrinherz Check if your Bellhop installation is working OK. Run it on the command line and see what it says. Also, if you pass in a debug=True flag to pm.compute_eigenrays, it'll retain the Bellhop input/output files for you to manually check. See if there are any errors in it.
I've had a few cases of users on OS X not being able to run Bellhop correctly using the gfortran install for version 10+. I use gfortran 6.3.0 on OS X, and that works fine.

@haozhao10 Please follow instructions on Acoustic Toolbox homepage on installing it. Then install Python support for it with pip install arlpy, and follow the instructions in the docs.

Hello Mandar,
Thank you for the prompt response. I checked again and saw that bellhop.exe
is on my PATH but when I run "bellhop.exe" from the command line it gives
me a segmentation fault. I have GFortran version 9.1.0 installed. Do you
have any idea about what causes segmentation fault? I tried adding
debug=True flag but it does not create any input/output files for me. I get
the same error as before. Please see the below screenshot. Appreciate your
help.
Plot_test python model.py
[DEBUG] Model: bellhop
[WARN] Bellhop did not generate expected output file
[DEBUG] Bellhop working files:
/var/folders/zl/x7khdv0s3ljg3bv_p8r2_y_h0000gn/T/tmp851srvsm.*

The segmentation fault seems to be the culprit. I've seen this happen with gfortran 10, and fixed it by switching to gfortran 6.3.0. Since bellhop.exe comes from OALIB, there isn't anything arlpy about it. You might want to either use an older gfortran or get in touch with Bellhop's author to see how to resolve the problem.

Hello @mchitre sir actually i am bit confused about how to solve this gfortran problem can you help. Do i have to download it and add it to environment variables ? Can you help

Yes, I believe you need gfortran libraries installed on your machine to run bellhop. I am not the author of bellhop, and so can't provide you support on installing and running it. arlpy provides a Python wrapper only, and you need a working copy of bellhop to use it.
P.S. You may want to look at https://github.com/org-arl/AcousticsToolbox.jl as a Julia alternative to arlpy, that I also maintain. That comes with pre-built binaries for bellhop for most systems, and might be easier to get started with, if you're having trouble installing bellhop from scratch.

@mchitre sir can you share the files installed in your jupyter notebook or environment setup to run this bellhop code in jupyter notebook.

@mchitre sir if it is possible. Can you upload a video on youtube on how to set up bellhop channel in python from scratch (Gfortran too) because there isn't any resources available to it.
It will be really helpful if it could be done

I'm sorry @GT-OP, I cannot provide support to install bellhop.exe, which is NOT part of arlpy. You need a working install of that to use this package. You may ask the author of bellhop for help, if you wish to.
