How to run Pytorch on Macbook pro (M1) GPU?

I tried to train a model using PyTorch on my Macbook pro. It uses the new generation apple M1 CPU. However, PyTorch couldn't recognize my GPUs.

GPU available: False, used: False
TPU available: False, using: 0 TPU cores
IPU available: False, using: 0 IPUs

Does anyone know any solution?

I have updated all the libraries to the latest versions.

Solution

  • PyTorch added support for M1 GPU as of 2022-05-18 in the Nightly version. Read more about it in their blog post.

    Simply install nightly: conda install pytorch -c pytorch-nightly --force-reinstall

    Update: It's available in the stable version:

    • Conda:conda install pytorch torchvision torchaudio -c pytorch
    • pip: pip3 install torch torchvision torchaudio

    To use (source):

    mps_device = torch.device("mps")

# Create a Tensor directly on the mps device
x = torch.ones(5, device=mps_device)
# Or
x = torch.ones(5, device="mps")

# Any operation happens on the GPU
y = x * 2

# Move your model to mps just like any other device
model = YourFavoriteNet()
model.to(mps_device)

# Now every call runs on the GPU
pred = model(x)
