Which version are you using?

[raffaem]

Thanks for the fast answer

Which version are you using?

$ python
Python 3.10.1 (tags/v3.10.1:2cd268a, Dec  6 2021, 19:10:37) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pybliometrics
>>> print(pybliometrics.__version__)
3.1.0

I'm pretty sure the issue is that the config.ini file is not in the same drive as the python script that uses pybliometrics.

I moved the Python script to the same drive of config.ini and it fixed the issue.

Or it may have been that the python script was on a network shared folder with UNC path.

[Michael-E-Rose]

I'm almost certain it's the latter. We had this issue too. Turned out to be two different home directories. You can check that with pybliometrics.scopus.CONFIG_FILE from different locations.

[raffaem]

so the gist is: don't put you python scripts in a network shared folder?

should we write that in the docs?

[raffaem]

Nada, looks like it's the exact same config file:

Turned out I didn't fix this bug as I though previously. But now it is :)

Must have been frightening for first-time users to get this long traceback upon creation of the configuration file - even though it would work on the second attempt.
