raise ValueError('Unexpected result of `predict_function` '
Hi Simon,
You did a excellent work for iPHoP. But when I use the code “iphop predict --fa_file bigger10k.part_003.fasta --db_dir iphop_db/Sept_2021_pub --out_dir output“, the following error was occured:
“Traceback (most recent call last):

The attachment is my input file.
Could you help me with the problem? Thanks in advance!

Hi !
I was initially worried that this was a Keras issue, but actually it’s simpler (and more stupid) than this. In essence, this is similar to issue
#5(https://bitbucket.org/srouxjgi/iphop/issues/5/keyerror-n-match).The bottom line is: if some methods come back with 0 results (in this case blast), this creates some empty files that are not always handled well. This is on our todolist to fix, but it will take a few weeks (at least). In the meantime, the same process that helped with issue 5 should work here, i.e.:
Hopefully this helps run iPHoP for now, while waiting for the bugfix !
