当我在 Google Colab 上运行以下命令时

!pip3 install --upgrade pip==20.0.2 wheel==0.34.2 setuptools==46.1.3
!pip3 install --upgrade --force-reinstall -e .

出错了

当我将 gast 版本 0.2.2 更新到 0.3.2 时，它说它再次需要 gast 版本 0.2.2，当我从 gast 版本 0.3.2 降级到 0.2.2 时，它说它再次需要 gast 版本 0.2.2（副-反之亦然） 在此处输入图像描述

首先不要忘记在运行当前单元后重新启动运行时。IE

!pip3 install folium==0.2.1
!pip3 install --upgrade pip==20.0.2 wheel==0.34.2 setuptools==46.1.3
!pip3 install --upgrade --force-reinstall -e .

# Restart Colab after this cell

我遇到了同样的错误。但它不影响训练，因为我们tensorflow-gpu==1.15.2在后面的步骤中重新安装（Deepspeech 的依赖项）（请先设置您的 GPU 配置，然后卸载并重新安装 tensorflow）。

### Setting-up GPU for training

#### Checking if we have nvidia or not

!nvcc --version
!nvidia-smi

#### Setting up environment variables for cuda

! echo $PATH

import os
os.environ['PATH'] += ":/usr/local/cuda-10.0/bin"
os.environ['CUDADIR'] = "/usr/local/cuda-10.0"
os.environ['LD_LIBRARY_PATH'] = "/usr/lib64-nvidia:/usr/local/cuda-10.0/lib64"

!echo $PATH
!echo $LD_LIBRARY_PATH
!source ~/.bashrc

!env | grep -i cuda

####  Adding freeglut and other OPENGL packaged for deepspeech requirement satisfaction

%cd /content/
!wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-repo-ubuntu1804_10.0.130-1_amd64.deb
!sudo apt-get install freeglut3 freeglut3-dev libxi-dev libxmu-dev
!sudo apt-get install build-essential dkms
!sudo dpkg -i cuda-repo-ubuntu1804_10.0.130-1_amd64.deb
!sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub

!sudo apt-get update
!sudo apt-get install cuda-10-0

!sudo rm /usr/local/cuda
!sudo ln -s /usr/local/cuda-10.0 /usr/local/cuda
%ls -l /usr/local/

**# Finally uninstalling and reinstalling tensorflow**
!pip3 uninstall tensorflow
!pip3 install 'tensorflow-gpu==1.15.2'

完成安装所有依赖项后，还可以使用以下代码段来修复损坏的依赖项

!sudo apt-get -o Dpkg::Options::="--force-overwrite" install --fix-broken
