Error during detector training

hello
i faced a problem during detector o my sample

here is the error message, it says i didn't use a negative dataset but actually i used one that is called GeneSwap_Negatives.pfam.tsv
i think deepbgc can't see the negative dataset because of a error o my command. --help didn't tell where or how to put it

my cmmand:

deepbgc train --model templates/deepbgc.json --output MyDeepBGCDetector.pkl sample1_deepbgc_prepare_result.tsv GeneSwap_Negatives.pfam.tsv --config PFAM2VEC pfam2vec
.csv -v ClusterFinder_Annotated_Contigs.full.gbk

Reproduce the shown deepbgc train command, then inspect deepbgc/command/train.py and deepbgc/util.py, especially read_samples, as named in the traceback. Determine how the two TSV inputs are assigned target values and document or correct the behavior so training accepts distinct positive and negative samples.
