All of a sudden: "ModuleNotFoundError: No module named 'cantera'"

[Anna Sophia Tombazzi]

Hey Guys, I'm fairly new at coding - I create some code a few months ago through spyder and was able to use cantera, etc. Now when I pull up the same code file (I did change the name) and try to run it, I get the error "ModuleNotFoundError: No module named 'cantera'"

What happened? It worked fine before. Thanks!

You need to source cantera. If you have a terminal interface try: pip install cantera.

I found the error, sharing it here in case helpful.

I had opened spyder separately (from windows application), and it wasn't loaded in the right conda environment which had cantera. To fix this, I worked through anaconda command prompt to:

Create a environment with cantera

Added spyder to that environment

*** USED conda command prompt to open spyder from that environment - no clicking through windows application.

 That solved it. Thanks!
