AttributeError: 'DecisionTreeClassifier' object has no attribute 'n_features_'

[TKSJ2020]

Hello,

I installed whokaryote with conda and I am trying to run using this:
whokaryote.py --contigs /home/shishido/Lichen_data/Meta_omics2023/contigs/contigs_L10.fasta --outdir whokaryote_outputL10 --f --threads 10

But I am getting some error (below), could you please help me with what I should do?

Output directory is whokaryote_outputL10
Size-filtered contigs already exist. Using those.
Tiara prediction file already present.

I'm sorry for the late response, I've had some personal circumstances that prevented me from working for some time. I hope you managed to get Whokaryote to work in the meantime! If not, could you please give me some more information? How many contigs did you end up using, and what is their minimum length? I usually see this error when there are not enough contigs left to do calculations on, or if the contigs contain only 1 gene or less because they are so short. You could try to check the feature table file to see if this is the case.
