Error on Import

[PGijsbers]

With the latest version, after installing I always get an error on first import:

>>> import lightautoml

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/venv/lib/python3.9/site-packages/lightautoml/__init__.py", line 19, in <module>

It seems to be an issue with opencv-python and requires an install of the python3-opencv package (apt-get install -y python3-opencv). Making the CV part of LAMA an optional install, or at least adding this to the documentation would be helpful.

Hi @PGijsbers,

Many thanks to let us know the issue.

Could you also tell us how it works before and stop working now? Maybe you have changed the start env or server OS or whatever? It can help us to define properly when to use the install because not always you have sudo rights on the servers..

I'm sorry, I don't know about any of that. I observed the issue running the benchmark script (in docker and on aws), I hadn't personally ran the framework before so I can't tell when the issues started or which version changed happened since. It does happen on the latest generic python docker image as well:

C:\Users\Work>docker run -it --entrypoint=/bin/bash python
root@0589c73becc1:/# pip install lightautoml

@PGijsbers could you tell the version of pip? Have you done beforehand pip install -U pip in your script?

[PGijsbers]

Above was generated with pip 21.1.3. Doing it again but updating pip to 21.2.1 beforehand gives the same result.

FWIW the python docker container is built on Debian:
