This is a duplicate of MIC-DKFZ/acvl_utils#2, but I'm re-reporting here just in case anyone else runs into this bug and tries to find it by checking nnUNet's issues.

Same problem !

Downgrading acvl_utils to version 0.2 gets rid of the initial error, though I haven't run any real work yet. So there might be other problems.
pip install --upgrade acvl_utils==0.2

I did the same thing: downgrading acvl_utils to version 0.2 worked for me. So far all my experiments seem to run.
