Issue with importing pysm

[Ankurdev-astro]

Hi,
I am running toast_ground_sim.py with [--pysm-model ] and [--pysm-apply-beam] parameters on toast v2.3.12 . I have pysm3 v3.3.2.dev46+g5c339f0 installed.
The pipeline throws an error : RuntimeError: PySM not available .

Should I have pysm installed, instead of pysm3 ?

! toast_ground_sim.py @toast_ground_sim.par
<toast.Environment
  Source code version = 8dbc082
  Logging level = INFO
  Handling enabled for 0 signals:
  Max threads = 128

In addition:
https://github.com/hpc4cmb/toast/blob/e24107daa99797a314d0e579a6351ee1f3b04aa0/src/toast/todmap/pysm.py

The pysm.py file imports

try:
    import pysm
    import pysm.units as u

But class PySMSky(object): documents " Requires PySM 3 "

Should pysm.py import pysm3 instead?

Yes, correct, you should change the import statement. We haven't used this functionality in a while so I'm not sure if it is still working properly. Please double check the outputs.
