i'm pretty sure it's a version mismatch - but couldn't figure out a way to fix it

according to an issuei found (ContinuumIO/anaconda-issues#9480 (comment)) exporting via conda env export --no-builds > environment.yml should help fix the issue.

[yhilpisch]

You are right. It should be done with --no-builds.

I am currently in the course of finishing up things -- and codes -- for the second edition.

The completely updated code base will be available soon in my repo.

I'm facing the same issue (conda version 4.6.8):

(base) C:\Users\owner\Documents\GitHub\py4fi>conda env create -f py4fi_conda.yml1

I suspect you'd want to use https://github.com/yhilpisch/py4fi2nd ... the repository for the 2nd edition ...

[xmatthias]

I guess i'll close this as the 2nd edition is now using a different repository which seems to work fine.
