🐛 Bug

When import torchmetrics in python, it reports the error.

To Reproduce

Install torchmetrics[audio]:

pip install torchmetrics[audio]

Import it in python:

import torchmetrics

Code sample

Expected behavior

Environment

• TorchMetrics version (and how you installed TM, e.g. conda, pip, build from source): 0.9.2
• Python & PyTorch Version (e.g., 1.0): Python 3.8.5, PyTorch 1.10.0
• Any other relevant information such as OS (e.g., Linux): Win 10

Additional context

[SkafteNicki]

Actual problem comes from torchvision and not torchmetrics:
pytorch/vision#1718
Either:

• Update torchvision to a newer version where it should have been fixed
• Install a version of pillow that is compatible: conda install pillow=6.2.1
