X has 630 features, but RandomForestClassifier is expecting 105 features as input

Hello

I am trying to run amPEPpy but I get an error message.

ofm@osmel-dell:~/Work/src/amPEPpy$ ampep predict -m amPEP.model -i training_data/XXXX.fasta -o XXXX.tsv --seed 2012

@ofleitas I have updated the code to work with newer versions (>=1.0.0) of scikit-learn. Please download and install the newest release of amPEPpy and see if this resolves your error.
