如何在 Google Colab 上安装 nvidia apex

How to install nvidia apex on Google Colab

我所做的就是按照官方 github 网站上的说明进行操作

!git clone https://github.com/NVIDIA/apex
!cd apex
!pip install -v --no-cache-dir ./

它给我错误:

ERROR: Directory './' is not installable. Neither 'setup.py' nor 'pyproject.toml' found.

已更新

首先,创建一个文件,例如setup.sh如下:

对于具有 CUDA 和 C++ 扩展的顶点:

%%writefile setup.sh

git clone https://github.com/NVIDIA/apex
cd apex
pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./

然后,安装它

!sh setup.sh

对于 Python-仅构建

%%writefile setup.sh

git clone https://github.com/NVIDIA/apex
cd apex
pip install -v --disable-pip-version-check --no-cache-dir ./

A Python-only 构建省略了使用 apex.optimizers.FusedAdamapex.normalization.FusedLayerNorm 等所需的某些 Fused 内核

检查apex quickstart

(只想添加评论,但我没有足够的声誉...)

它对我有用,但实际上不需要 cd。另外,我需要这里建议的两个全局选项:https://github.com/NVIDIA/apex/issues/86

%%writefile setup.sh

git clone https://github.com/NVIDIA/apex
pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./apex

然后

!sh setup.sh

添加 CUDA_HOME 环境变量后为我工作:

%%writefile setup.sh

export CUDA_HOME=/usr/local/cuda-10.1
git clone https://github.com/NVIDIA/apex
pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./apex
!sh setup.sh

在 colab 中而不是使用“!”在 cd 命令

之前使用“%”
!git clone https://github.com/NVIDIA/apex
%cd apex
!pip install -v --no-cache-dir ./

上面的代码可以正常工作。

问题出在 !cd apex。请改用 %cd apex

读这个:

我尝试了几个选项,但我喜欢 this website 中的那个,它与 fast_bert 和 torch 配合使用非常好:

try:
  import apex
except Exception:
  ! git clone https://github.com/NVIDIA/apex.git
  % cd apex
  !pip install --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" .
  %cd ..

我使用 paperspace,这对我有用:

!pip install git+https://github.com/NVIDIA/apex
