Performance problems leading to installer errors

[bdulfer]

Since yesterday afternoon I have performance problems showing up as a delay of several seconds before the sampling starts.

Screen looks like this:

Data shape for DDIM sampling is (1, 4, 80, 64), eta 0.0
Running DDIM Sampling with 20 timesteps
DDIM Sampler: 0%|                                                             |

After about ten seconds sampling starts.

To check if this is due to extensions or other stuff on my system, I did a fresh clone.
Running webui.sh leads to the following error:

################################################################
Launching launch.py...
################################################################
Traceback (most recent call last):
  File "/data/bernd/vlamandic/launch.py", line 19, in <module>
    setup.parse_args()
  File "/data/bernd/vlamandic/setup.py", line 446, in parse_args
    from modules.script_loading import preload_extensions
  File "/data/bernd/vlamandic/modules/script_loading.py", line 3, in <module>
    import modules.errors as errors
  File "/data/bernd/vlamandic/modules/errors.py", line 3, in <module>
    from rich import print # pylint: disable=redefined-builtin
ModuleNotFoundError: No module named 'rich'

The root cause is obvious: rich is not installed.
But since it is in requirements.txt, it should be installed by the setup routine.
But the setup routine is using it to report errors.
So we have a circular dependency.

I can solve this in some different ways. But I think I should discuss the solution beforehand.
My proposal is to modify modules/errors.py to check if rich is missing and use a simple print() when that's the case.
Or to use some try/except mechanism for the same purpose.

How about that?

And how would I send in patches? I'm pretty new to this git stuff.

After fixing this I would try to find the cause of the performance problems.

I just saw that there is already an issue open: #291
