Reinstate tomopy #47

Open danielballan opened 2 years ago

danielballan commented 2 years ago

In the last month or two, our CD build broke because mamba was unable to solve for tomopy. The symptom on GH Actions was just a hang in mamba update ... step (not sure why) but locally I was able to get a clear error message:

$ time micromamba create -f binder/environment.yml  -p from_file --dry-run

    It will be handled as env name, resulting to the following

In #46 I removed tomopy to resolve the issue.
