Question about bellhop install in linux about arlpy HOT 7 CLOSED

Great!

from arlpy.

Does typing bellhop.exe on command line run Bellhop? If so, make sure you start Python or Jupyter from the same terminal where this works.

P.S. You may need to put this in your .bashrc or .profile file to ensure the PATH is set correctly every time you start a terminal.

Thank you, I think it work.
But when I trying to run an example file at_2020_11_4/tests/arctic/arctic.env, it came up with 'Stop Fatal Error:Check the print file for detail.'
Here is the content of env file and print file.

*** FATAL ERROR ***
Generated by program or subroutine: BELLHOP - READIN
Unable to open the environmental file

from arlpy.

Also, I try to run a python code with arlpy.
Like this:

import arlpy.uwapm as pm
import arlpy.plot as plt

bathy = [
[0, 30], # 30 m water depth at the transmitter
[300, 20], # 20 m water depth 300 m away
[1000, 25] # 25 m water depth at 1 km
]
ssp = [
[0, 1540], # 1540 m/s at the surface
[10, 1530], # 1530 m/s at 10 m depth
[20, 1532], # 1532 m/s at 20 m depth
[25, 1533], # 1533 m/s at 25 m depth
[30, 1535] # 1535 m/s at the seabed
]
env = pm.create_env2d(depth=bathy,
soundspeed=ssp,
bottom_soundspeed=1450,
bottom_density=1200,
bottom_absorption=1.0,
tx_depth=15)
pm.print_env(env)
rays = pm.compute_rays(env)
pm.plot_rays(rays, width=1000)

It also came up with:'Stop Fatal Error:Check the print file for detail.'

How can I fix this?
Thank you for your help.

For your problem re running Bellhop directly, the clue is in the error output: Unable to open the environmental file and /mypath/at_2020_11_4/Bellhop/arctic.env.env. Note the .env.env that Bellhop is trying to read, whereas your env file probably has only one .env. Bellhop automatically assumes the .env and so when running Bellhop, you should run it as bellhop.exe /mypath/at_2020_11_4/Bellhop/arctic without the .env.

For any further guidance on using Bellhop without arlpy, please consult Bellhop's documentation, and if you have doubts, contact Bellhop's author.

For your problem running Bellhop from arlpy, try a simpler environment example (e.g. from the docs) to check if your installation is fine. If it is, you can use rays = pm.compute_rays(env, debug=True) to ask arlpy to retain the Bellhop print file for you to check what the error might be.

Ok, Thank you for your answer.
I think think the problem solved.
