Quantile attribute error when using Topaz


We tried to run the topaz (train) job from CryoSparc and get this following error message:

Traceback (most recent call last):
  File "cryosparc2_worker/cryosparc2_compute/run.py", line 78, in cryosparc2_compute.run.main
  File "cryosparc2_compute/jobs/topaz/run_topaz.py", line 298, in run_topaz_wrapper_train
    assert len(glob.glob(os.path.join(model_dir, '*'))) > 0, "Training failed, no models were created."
AssertionError: Training failed, no models were created.

If we look at the log file, further up, there is also this error message:

AttributeError: module 'numpy' has no attribute 'quantile'

It seems to come from numpy, but as far as I understand, Cryosparc maintains its own Python instance, so updating our wouldn’t help, right?

Would anyone know where this error comes from and how to solve it?


Hi @ncoudray,

If you followed the instructions on the Topaz Github page, you should’ve installed topaz into a new anaconda environment. If you look at the setup.py file, you’ll see that Topaz requires:


Can you make sure these requirements are satisfied?

Thanks for the reply and Happy New Year - We will have a look.
