Question

系统：Windows 10 64位，python 3.6.5 64位。使用水蟒。 CUDA 10.0，已安装cuddn。

美好的一天。出于安全原因，我们公司拒绝访问Internet。我从TF tensorFlow官方网站下载了软件包：

https: //storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-1.14.0-cp36-cp36m-win_amd64.whl

我尝试使用pip安装它：

pip install --upgrade D:\tensorflow_gpu-1.14.0-cp36-cp36m-win_amd64.whl

我收到以下消息：

collecting keras-preprocessing>=1.0.5 (from tensorflow-gpu==1.14.0)
Retrying ....after connection broken by 'NewConnectionError'
......
could not find a version that satifies the requirement keras-preprocessing=>1.0.5.....
no matching distribution found for keras-preprocessing=>1.0.5 (from tensorflow-gpu==1.14.0)

重新启动时，找不到其他一些TensorFlow依赖项，据我了解，pip根本看不到任何依赖项

我认为WHL软件包具有所有必要的依赖性，但是在安装pip时，它将尝试从Internet下载某些内容。告诉我我在做什么错了吗？

pip检查tensorflow结果：

(base) C:\Windows\system32>pip check tensorflow

tensorflow 1.10.0 requires absl-py, which is not installed.

distributed 1.21.8 requires msgpack, which is not installed.
tensorflow-gpu 1.14.0 has requirement numpy<2.0,>=1.14.5, but you have numpy 1.14.3.
tensorflow-gpu 1.14.0 has requirement wrapt>=1.11.1, but you have wrapt 1.10.11.

我认为WHL软件包具有所有必要的依赖关系

不。车轮不包含所有依赖关系，也不应该包含所有依赖关系，否则每个车轮都会极度膨胀。如果必须在无法访问互联网的计算机上安装tensorflow-gpu（或其他轮子），请执行以下步骤：

在具有互联网访问权限的计算机上，运行：
```
\> pip download tensorflow-gpu --dest some\dir
```
（您可以通过运行包含包含已下载的--dest的目录作为tensorflow_gpu-1.14.0-cp36-cp36m-win_amd64.whl来运行此命令，因此不必再次下载它）

这将下载tensorflow-gpu及其所有依赖项树。
现在将目录（包含所有下载的文件）传输到计算机上，而无需访问Internet并运行：
```
\> pip install tensorflow-gpu --no-index --find-links some\dir
```
--no-index将指示pip不要在线查找软件包，--find-links将指向本地目录，可以在其中找到要安装的软件包。

TensorFlow WHL文件为什么不包含所有必需的依赖项？
