I would like to learn to use TensorFlow but, of course, I am not even able to install it!

These are the info about my case:

• Python 3.6 64-bit


• Intel(R) HD Graphics 520


• Intel i7


• Windows 7


• numpy 1.14.1

I have followed these steps:

1. On cmd: C:> pip3 install --upgrade tensorflow-gpu
   


2. On Python: import tensorflow
   

But I get the following error:

Traceback (most recent call last):
 File "C:UsersVESAppDataLocalProgramsPythonPython36libsite-packagestensorflowpythonplatformself_check.py", line 62, in preload_check
 ctypes.WinDLL(build_info.nvcuda_dll_name)

 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:

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:WindowsSystem32'. If it is not present, ensure that you have a CUDA-capable GPU with the correct driver installed.

To run tensorflow with GPU support you'll need a NVIDIA graphic card and the CUDA libraries installed (see requirements here), unfortunately your Intel(R) HD Graphics 520 won't do.

You can settle for the CPU version (pip3 install --upgrade tensorflow), which is still good to start learning.

UPDATE: another solution is to use the online service Google Colab, which allows you to borrow a GPU from Google's cloud infrastructure for learning purposes.
