M1 MAX: GPU available, but not used

Dear all,
I am trying to train scvi model (macOS, M1 MAX, scvi-tools (0.20.3)). GPU is available, but not used.

and the command:


MisconfigurationException: MPSAccelerator can not run on your system since the accelerator is not available. The following accelerator(s) is available and can be passed into accelerator argument of Trainer: [‘cpu’].

import torch
import math
print(torch.backends.mps.is_available()) ----> True
print(torch.backends.mps.is_built()). ----> True

How to activate GPU and make use of it? Can anybody help me to solve this issue?

Thank you.

Hi, what kind of environment are you running this in? I would recommend using a conda version that is native for Mac M1 Miniconda — conda documentation

I should add that currently, even if MPS was working, most scvi-tools models will not work as there is no MPS implementation of the lgamma function.

The only one I’ve tested that works is peakVI.

Thank you Adam for your answer!!
Anyway, I am very grateful for the tool and that it is working on M1 MAX on cpu now.

I am running it in miniforge3 (arm64).
