Bug on a fresh install

[asaldivar93]

When running checkm2 on a new environment I got this error:

Traceback (most recent call last): File "/opt/asaldivar/miniconda3/envs/checkm2/bin/checkm2", line 27, in <module> from checkm2 import predictQuality File "/opt/asaldivar/miniconda3/envs/checkm2/lib/python3.6/site-packages/checkm2/predictQuality.py", line 1, in <module> from checkm2 import modelProcessing File "/opt/asaldivar/miniconda3/envs/checkm2/lib/python3.6/site-packages/checkm2/modelProcessing.py", line 17, in <module> from tensorflow import keras File "/opt/asaldivar/miniconda3/envs/checkm2/lib/python3.6/site-packages/tensorflow/__init__.py", line 41, in <module> from tensorflow.python.tools import module_util as _module_util File "/opt/asaldivar/miniconda3/envs/checkm2/lib/python3.6/site-packages/tensorflow/python/__init__.py", line 41, in <module> from tensorflow.python.eager import context File "/opt/asaldivar/miniconda3/envs/checkm2/lib/python3.6/site-packages/tensorflow/python/eager/context.py", line 28, in <module> from absl import logging File "/opt/asaldivar/miniconda3/envs/checkm2/lib/python3.6/site-packages/absl/logging/__init__.py", line 97, in <module> from absl import flags File "/opt/asaldivar/miniconda3/envs/checkm2/lib/python3.6/site-packages/absl/flags/__init__.py", line 35, in <module> from absl.flags import _argument_parser File "/opt/asaldivar/miniconda3/envs/checkm2/lib/python3.6/site-packages/absl/flags/_argument_parser.py", line 82, in <module> class ArgumentParser(Generic[_T], metaclass=_ArgumentParserCache): TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

Traced it back to a Tensorflow issue: #64926

The hotfix was:

pip install absl-py==1.1.0

Thanks, this was also the issue on our installation.

Same here, installed via conda. Any ideas?
