igrf14coeffs.txt cannot be found using default installation via pip

Problem statement:

There was a previous installation of 0.3.3, which operated correctly. I upgraded to v1.0.0 using pip install pyIGRF --upgrade. After a successful upgrade, I attempted to re-run my script, but got the following errors:

import pyIGRF # Geomagnetic field model
File "/Users/testaccount/Documents/project/venvdir/lib/python3.9/site-packages/pyIGRF/init.py", line 11, in

FileNotFoundError: [Errno 2] No such file or directory: '/Users/testaccount/Documents/project/venvdir/lib/python3.9/site-packages/pyIGRF/src/igrf14coeffs.txt'

Hypotheses:

• Looking at the merged pull request update to igrf14 and remove numpy #13 , I suspect that pyIGRF.egg-info/SOURCES.txt may have been modified incompletely, especially this line where the igrf13coeffs.txt file is removed, but not replaced with the igrf14coeffs.txt file:

- pyIGRF.egg-info/top_level.txt
- pyIGRF/src/igrf13coeffs.txt
+ pyIGRF.egg-info/top_level.txt

• Is it a requirement to manually download & install the igrf14coeffs.txt file?

Unfortunately since the original author doesn't reply, I had to republish the package under https://github.com/OpenSpeleo/pyIGRF14 and fixing the bugs and numerous packaging issues.

pip install pyIGRF14

Using the following will be backward compatible:

import pyIGRF14 as pyIGRF
