Question

我想学习使用TensorFlow，当然，我甚至无法安装它！

这些是关于我案例的信息：

Python 3.6 64位
英特尔（R）HD Graphics 520
Intel i7
Windows 7
numpy 1.14.1

我已按照以下步骤操作：

在cmd上：C:\> pip3 install --upgrade tensorflow-gpu
在Python上：import tensorflow

但是我收到以下错误：

Traceback (most recent call last):
  File "C:\Users\VES\AppData\Local\Programs\Python\Python36\lib\site-packages\tensorflow\python\platform\self_check.py", line 62, in preload_check
    ctypes.WinDLL(build_info.nvcuda_dll_name)
  File "C:\Users\VES\AppData\Local\Programs\Python\Python36\lib\ctypes\__init__.py", line 348, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: [WinError 126] The specified module could not be found

During handling of the above exception, another exception occurred:

    import tensorflow

ImportError: Could not find 'nvcuda.dll'. TensorFlow requires that this DLL be installed in a directory that is named in your %PATH% environment variable. Typically it is installed in 'C:\Windows\System32'. If it is not present, ensure that you have a CUDA-capable GPU with the correct driver installed.

Answer 1

要在GPU支持下运行tensorflow，您需要安装NVIDIA显卡并安装CUDA库（请参阅requirements here），遗憾的是您的 Intel（R）HD Graphics 520 不会做。

您可以选择CPU版本（pip3 install --upgrade tensorflow），这仍然可以开始学习。

更新：另一种解决方案是使用在线服务Google Colab，它允许您从Google的云基础架构借用GPU用于学习目的。

import TensorFlow：[WinError 126]找不到指定的模块
