I'm trying to call a python function in a file in my ruby on rails application.

My python file is located at project_dir/lib/assets/python/the_file.py I'm utilizing PyCall for ruby with the lines:

require 'pycall'
PyCall.sys.path.append('/lib/assets/python')
file_import = PyCall.import_module("the_file")

I get an error saying <class 'ModuleNotFoundError'>: No module named 'the_file'

Is it just a syntax error? Is there a better different way I should be trying to run my python script in rails?

I am using ruby 3.0.0, rails 7.0.2, and python 3.11

Use a relative path:

PyCall.sys.path.append('./lib/assets/python')
