"import tensorflow as tf" ImportError: Could not find 'cudart64_90.dll'

I am trying to learn Python and specifically TensorFlow. I have followed the instructions and have overcome several problems so far and have successfully installed TensorFlow (pip install), CUDA(9.1.85 win10), Python(3.6.3 amd64), and CUDNN(8.0 win10x64) as I have a GPU (GTX 1080) and want to be able to train networks with it. My computer has an intel i7, and Windows 10. I started with CUDA(8.0.61 win10) but it caused an error that said it needed version 9.

When I try to test with

>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> print(sess.run(hello))

I get this error on the first line

>>> import tensorflow as tf
Traceback (most recent call last):
  File "C:\Program Files\Python36\lib\site-packages\tensorflow\python\platform\self_check.py", line 75, in preload_check
    ctypes.WinDLL(build_info.cudart_dll_name)
  File "C:\Program Files\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:

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import tensorflow as tf
  File "C:\Program Files\Python36\lib\site-packages\tensorflow\__init__.py", line 24, in <module>

    % (build_info.cudart_dll_name, build_info.cuda_version_number))
ImportError: Could not find 'cudart64_90.dll'. TensorFlow requires that this DLL be installed in a directory that is named in your %PATH% environment variable. Download and install CUDA 9.0 from this URL: https://developer.nvidia.com/cuda-toolkit

How can I fix this?

PS: I have read all other questions about this on this site and have also read the common problems page. I'm sorry the errors don't seem to match my specific problem but obviously I am lost here.

Tensorflow does not currently support CUDA 9.1 see (may change soon though): https://github.com/tensorflow/tensorflow/issues/15656

You can download and install CUDA 9.0 from this URL: https://developer.nvidia.com/cuda-toolkit
