Process isolation is not working on MPS device

[baptistecolle]

Setting up the launcher to process on an MPS device causes the benchmark to be stuck permanently on “Sending report to main process.”

Steps to reproduce:
Run this configuration on an MPS device (Mac M-series).

defaults:
  - benchmark
  - scenario: inference
  - **launcher: process # launcher: inline works**
  - backend: pytorch
  - _base_
  - _self_

name: pytorch_bert

scenario:
  latency: true
  memory: true
  input_shapes:
    batch_size: 1
    sequence_length: 128

backend:
  device: mps
  no_weights: true
  model: bert-base-uncased

(example adapted from pytorch_bert.yaml)

Temporary Solution: set to launcher: inline

Remarks: launcher.start_method: fork does not also work on mac

now that I think about it, this might be a problem in your shared memory size, did you run this on docker ?

No, i installed the project from source and ran it
