如何在Mac M1上安装FastAi

Question

我正在尝试在新的Mac M1上安装FastAi（1.0.61版）。

我首先尝试了：

pip install fastai==1.0.61

这给了我一个没有CMAKE的错误，因此我使用 Brew install cmake 成功安装了CMAKE。

然后，重新启动FastAi安装命令，我会收到此错误：

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

我显然无法安装 pynvx 。这是有道理的，因为 pynvx 涉及CUDA，显然Mac M1无法支持。我尝试了CPU仅在此处从Fastai构建安装文档：

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

但是我遇到了同样的错误。

我能做些什么？如果我不能在本地训练模型，那还可以，但是我至少希望能够加载模型并预测它们。

Answer 1

Fastai似乎需要 pyenv 需要CUDA才能工作。 CUDA仅在NVIDIA GPU上可用，Mac M1具有完全不同的SOC，没有NVIDIA GPU，

您可以阅读实际错误

Answer 2

我可以在第一章中获得第一个培训示例，以在我的Mac Mini上使用M1。我正在使用Ventura（Beta），但我认为这并不重要。最新的Xcode可以。我已经尝试并失败了很多次来实现此功能，如果您也有，那么看到它实际上播放真的很有趣，即使只是一点点。但是我可以用一些帮助将其哄骗。

我制作了一个bash脚本，可以创建一个Miniconda环境，并在MacOS上的Jupyter笔记本中安装了运行FastAi所需的一切。我是Conda，Python和Fastai的新手，因此可能有更好的方法可以做到这一点，但它对我有用，并且可以重现。

我们需要下载FastBook，但是在撰写本文时，我们还需要一些出血的Edge Nightly Source构建才能使这项工作。因此，制作一个空目录并进入其中。然后运行此脚本，为其提供您希望创建的新虚拟环境的名称。安装所有内容将需要几分钟，而且运气可能会不会出错。就是这样。

Conda激活环境，然后运行Jupyter笔记本。从那里导航到快速书 /清洁 / 01_intro。

您将需要编辑任何数据加载程序，以添加显式“ num_workers = 0”参数。因此，第一个笔记本电脑将看起来像：

# 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)

运行时，第一个示例通常会显示折旧警告（将其更改为“ Arch = Resnet34”，而不是仅仅是“ Resnet34”可以修复它）。但是无论是否警告，它都会运行：进度栏很快就会出现，任务在大约五分钟内完成（对我来说）。

这是我创建或更新环境的脚本。

时间到了，今天，您可以在M1芯片上运行Fastai。
虽然您必须为很多问题做好准备。

这是我的详细经验：

但是，长话短说，CPU从开箱即用。要使用GPU加速度，您需要将设备设置为MPS以使用Pytorch中的Apple Cuda模拟。
GPU用法：
