Hi Mr. Smith ,

Thank you very much for your prompt reply.

As instructed, I changed my own environment (anaconda) and executed it with the latest yt

( yt   4.0.1  py310hb5077e9_1  conda-forge),

referring to the following URL.

https://yt-project.org/docs/dev/installing.html

However, the error did not improve and I got the same one....

If you have anything else to try, please let me know.
