imagecodecs python库不会安装

Question

我试图在 Jetson Xavier 上使用 pip 安装 python scikit-image 库，但收到一条非常长的错误消息，表明它未能为“imagecodecs”库构建轮子。我尝试自行安装图像编解码器并收到类似的错误消息。

看了一圈，发现this的问题，错误和我的一模一样。但是，更新 pip 的解决方案并没有解决问题。

错误信息：

尝试使用此命令升级 pip。

sudo -H pip3 install --upgrade pip
sudo -H pip2 install --upgrade pip

pip 现在应该是最新版本。

 $ pip3 --version
pip 20.1.1 from ...

然后使用 pip3 安装

pip3 install scikit-image
