Python 3.10 support?

[egorananyev]

Installing through conda forge on python 3.10
conda install -c conda-forge cesium
I get the following:

• cesium -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.8,<3.9.0a0|>=3.7,<3.8.0a0']
  Your python: python=3.10

Installing through pip seems to work, and I can import cesium, but none of the modules are recognized. E.g., running
cesium.featurize.featurize_time_series()
yields:

module 'cesium' has no attribute 'featurize'

ls /Users/username/Library/miniconda3/envs/sklearn/lib/python3.10/site-packages/cesium/

init.py data_management.py features setup.py time_series.py version.py
pycache datasets featurize.py tests util.py

Thanks for reporting, but I don't think this is a bug; you have to do import cesium.featurize or from cesium import featurize to bring in the submodule.

Thanks, this worked! I copied the import code straight from a book called "Practical Time Series Analysis," but it didn't work in my case.

Oh dear, that's not right! Please let the author know.

We can also add lazy loading of submodules, which will allow access to submodules. I'll file an issue.

I just realized I never posted the import code that's used in the book. Just including it in case anyone encountered the same issue (maybe it's a version thing):

from cesium import featurize.featurize_time_series as ft

This yields the following error:

from cesium import featurize.featurize_time_series as ft
^
SyntaxError: invalid syntax

(the ^ points to the period after "featurize")
