explosion / catalogue

There's a stackoverflow post that seems to point at a problem with catalogue:

File "C:\Users\user1\AppData\Local\Continuum\anaconda3\envs\py37\lib\site-packages\catalogue.py", line 8, in
import importlib.metadata as importlib_metadata
ModuleNotFoundError: No module named 'importlib.metadata'

Referring to https://github.com/explosion/catalogue/blob/master/catalogue.py#L8, which makes no sense to me as ModuleNotFoundError is a subtype of ImportError and that is properly caught as an exception.

There's a lot of other things going on in those error logs, too, but this caught my attention and wanted to log this here for future reference.

One thing I noticed, going through the code here, is that catalogue doesn't have a __init__.py - should it ?

Yeah, that's weird. I guess we could just use a naked except here, even though that's kinda bad? The main thing we're trying to achieve here is check whether the user is on 3.8 / already has importlib.metadata as a builtin and if not, use the fallback package.

It's a single-file module, so it doesn't need one. Here's the relevant setting:

catalogue/setup.cfg

I am facing this error while importing spacy,

Traceback (most recent call last):

    import importlib.metadata as importlib_metadata

During handling of the above exception, another exception occurred:

I am using Python 3.6, in CentOS Linux 7. Any idea @ines. TIA :)

From the other issues I see that, pathlib is causing the problem. I am having wrapt_timeout_decorator as a dependency and which requires pathlib 🤕
Also I don't see this problem in MacOS, I have both of them installed and everything works good. But I face this in linux server. Gotta find a way! Will update if I could do some workaround

import 'importlib.metadata' try-catch doesn't work on Jupyter?
