Error in Import pyrom

[pradhancda]

Please suggest the possible solutions for following error

import pyroms Traceback (most recent call last): File "", line 1, in File "c:\pyroms_sp\pyroms\pyroms\pyroms__init__.py", line 19, in from . import tools File "c:\pyroms_sp\pyroms\pyroms\pyroms\tools.py", line 4, in from . import _iso ImportError: DLL load failed while importing _iso: The specified module could not be found.

[kshedstrom]

That _iso thing is a compiled object file with a full name something like _iso.cpython-310-x86_64-linux-gnu.so If it built correctly, according to the "pip install -e pyroms/pyroms", then it will be in that pyroms/pyroms directory. Do you have any such files?

[pradhancda]

Sir, Thank you, I trying in Anaconda under Windows. _iso.cp310-win_amd64.pyd ...This file is available in C:\pyroms_sp\pyroms\pyroms\pyroms.

[kshedstrom]

I'm sorry, I have no idea about Windows.

[pradhancda]

Can you please help ? how to solve the below problem. I am using Anaconda in Windows

import numpy, scipy, matplotlib, basemap, netCDF4, cftime, lpsolve55 import pyroms Traceback (most recent call last): File "", line 1, in File "c:\users\hp\pyroms\pyroms\pyroms__init__.py", line 19, in from . import tools File "c:\users\hp\pyroms\pyroms\pyroms\tools.py", line 4, in from . import _iso ImportError: DLL load failed while importing _iso: The specified module could not be found. import pyroms_toolbox Traceback (most recent call last): File "", line 1, in File "c:\users\hp\pyroms\pyroms_toolbox\pyroms_toolbox__init.py", line 12, in from .iview import iview File "c:\users\hp\pyroms\pyroms_toolbox\pyroms_toolbox\iview.py", line 5, in import pyroms File "c:\users\hp\pyroms\pyroms\pyroms\init__.py", line 19, in from . import tools File "c:\users\hp\pyroms\pyroms\pyroms\tools.py", line 4, in from . import _iso ImportError: DLL load failed while importing _iso: The specified module could not be found. import bathy_smoother

Sir, I also tried in Ubuntu 22.04, but there is no such file like _iso.cpython-310-x86_64-linux-gnu.so. and still shows the error.

You do need to have a working fortran compiler. It should compile with gfortran once you load the gcc compiler collection.

Hi, I am having a similar error once I successfully installed pyroms.

$ pip install -e pyroms/pyroms
Using pip 23.3.2 from /home/bendoni/miniconda3/envs/py38/lib/python3.8/site-packages/pip (python 3.8)

  Preparing metadata (setup.py): started
  Preparing metadata (setup.py): finished with status 'done'
Installing collected packages: pyroms
  Running setup.py develop for pyroms
Successfully installed pyroms-0.0.0

Then, if in a python shell I try: >>> import pyroms I get the follwoing error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/bendoni/scripts/roms/pyroms/pyroms/pyroms/__init__.py", line 19, in <module>

I am working on a linux machine under the conda environment py38 activated with all packages indicated in the instructions for installation. Have you gat oany suggestion on how to fix it?
