Problem with installation of PyGnome

[rsbragio]

Hi, I am trying to install PyGnome model and, although it seems to complete the installation, I had the following errors when running the script from Spyder:

c:\users\rs\pygnome\py_gnome\gnome_init_.py:62: UserWarning: ERROR: The gridded package, version >= 0.3.0 needs to be installed:
warnings.warn(msg)
Traceback (most recent call last):

from .cy_gnome import cy_basic_types as cbt
ImportError: DLL load failed while importing cy_basic_types: The specified procedure could not be found.

When running directly using the command "python name_of_script.py", the following error message came:
from gnome.spill import point_line_release_spill
ModuleNotFoundError: No module named 'gnome.spill'

I am following the installation procedure from https://gnome.orr.noaa.gov/doc/pygnome/installing.html#building-installing-pygnome-with-the-conda-package-manager, but it seems that some packages are not being installed correctly.

I would like to ask for your help in this issue.

Thanks.

Just to verify, are you in the 'gnome' environment you created in those instructions? Usually these sort of 'not found' problems after installation are due to either your terminal or your installation not being in the correct environment.

Hi Jay,
Yes. In both trials, I ran the script from inside the Gnome environment.

gnome.spill was renamed to gnome.spills for consistency. sorry, for that inconvenience and lack of backwards compatibility with existing scripts.

Hy Amy,
Thanks very much for the information. I tried renaming gnome.spills to gnome.spill, but the error continues. Shall I wait for some correction on the installation files, or shall I try something else to correct?

A few more questions. What branch of PyGNOME are you working in? Default is "main". Also, if you are in the environment you set up for GNOME, in Python are you able to do "import gnome" successfully?

[rsbragio]

I am not sure about what branch I am working in. I followed the instructions from https://gnome.orr.noaa.gov/doc/pygnome/installing.html.

During installation, I have not seen any option about using any other branch. In fact, I do not know what a branch is. The command I have used for importing gnome was:
git clone https://github.com/NOAA-ORR-ERD/PyGnome.git

After cloning the directory, I created the PyGnome environment using:
conda create -n gnome --file conda_requirements.txt

It seems that all files were downloaded correctly.
