Diamond version incompatible / TypeError: sequence item 0

[chumphati]

Hi,

I have a problem installing CarveMe related to diamond. The version downloaded with conda (0.9.14) as recommended on the installation page returns the error:

Error: Database was built with a different version of diamond as is incompatible.
Failed to run diamond.

When I upgrade the diamond version (to 2.1.8), I get this initial error:

carve --dna -o SRR5329951 assemblies/SRR5329951.fasta

I get the same error when downgrading python to 3.6.

Thank you for your help.
