Saved models could not be loaded: 'str' object has no attribute 'decode'

[xinehc]

The installed checkm2 v1.0.1 returns an error saying that the model could not be loaded. testrun seems not working. Manual installation with checkm2 v1.0.2 by git clone and python setup install also has this problem.

mamba create -n checkm2 -c bioconda -c conda-forge checkm2
checkm2 database --download
checkm2 testrun
