How to install fastai on Mac m1

Question

I am trying to install fastai (version 1.0.61) on my new Mac m1.

I first tried:

pip install fastai==1.0.61

This gave me an error that I didn't have cmake, so I installed cmake successfully with brew install cmake.

Then, rerunning the fastai install command, I get this error:

╰─> pynvx

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

I am clearly unable to install pynvx. This makes sense because pynvx deals with CUDA, which apparently Mac M1 cannot support. I tried the CPU only build install documentation from fastai here:

https://fastai1.fast.ai/install.html

But I get the same error.

What can I do? If I can't train models locally that's okay, but I want to at least be able to load models and predict with them.

Answer 1

Time goes, and today, you can run FastAI on the M1 chip. Though you have to be ready for a lot of issues.

Here is my detailed experience: https://medium.com/@johnniet19/fastai-2022-on-macbook-m1-pro-max-gpu-faa51d379a8c

But, long story short, the CPU works from out of the box. To use the GPU acceleration, you need to set a device to MPS to use APPLE CUDA analog in PyTorch. GPU usage:

Time for the first training in the 1st lesson:

Answer 2

I can get the first training example in chapter one to use the M1 on my mac mini. I'm using Ventura (beta), but I don't think that matters. The latest Xcode does. I've tried and failed many times to get this working, and if you have too, it's really fun to see it actually play, if only a little. But I could use some help coaxing it farther.

I made a bash script that creates a miniconda environment and installs everything needed to run fastai in jupyter notebook on macOS. I'm new to conda and python and fastai so there may be better ways to do this, but it works for me and is reproducible.

We need to download fastbook, but at the time of this writing we also need some bleeding edge nightly source builds to make this work. So make an empty directory and cd into it. Then run this script, giving it the name of a new virtual environment you'd like it to create. It will take several minutes to install everything, and with some luck may finish without error. That's it.

Conda activate the environment, then run jupyter notebook. From there navigate to fastbook / clean / 01_intro.

You will need to edit any DataLoaders to add an explicit "num_workers=0" argument. So the first notebook will look like:

# CLICK ME
from fastai.vision.all import *
path = untar_data(URLs.PETS)/'images'

def is_cat(x): return x[0].isupper()
dls = ImageDataLoaders.from_name_func(
    path, get_image_files(path), valid_pct=0.2, seed=42,
    label_func=is_cat, item_tfms=Resize(224), num_workers=0)

learn = vision_learner(dls, resnet34, metrics=error_rate)
learn.fine_tune(1)

When run, the first example usually shows a deprecation warning (changing it to "arch=resnet34" instead of just "resnet34" may fix it). But warning or not, it runs: a progress bar is quickly presented, and the task finishes in about five minutes (for me).

Here's my script to create or update the environment.

#!/usr/bin/env bash

set -e

        printf "Continue installation? (y/N): "
        read reply
        if [ "$reply" != "y" ] && [ "$reply" != "Y" ]; then
            echo "no change"
            exit 1

Answer 3

fastai seems to need pyenv which needs CUDA to work. CUDA is available only on Nvidia GPUs and the MAC M1 has a completly differente SOC with no Nvidia GPU
