无法在 Windows 上安装 apex

Question

我要安装apex on my computer with Windows 10 and cuda 9.0. I know apex is not recommended to be installed on Windows, but I still very much want to try it. I used These two commands provided on apex official website:

pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext"

和

pip install -v --no-cache-dir

但在两种情况下都出现错误：

ERROR: You must give at least one requirement to install (see "pip help install")

整个消息是：

>pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext"

您可能会收到错误，因为您错过了命令末尾的点：

pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" .
