Anaconda Integration with Cuda 9.0 shows Incompatible Package Error
I am trying to install CUDA 9.0  with NVIDIA-SMI: 445.75 in Windows 10. 

My Cuda 9.0 installation is successful, as shown from Command-prompt   

*(DL) C:\Users\User&gt;nvcc --version

**Cuda compilation tools, release **9.0**, V9.0.176***


(1) I downloaded cudnn-9.0-windows10-x64-v7.zip, extracted it, and moved it to the fold, which was created when Cuda was installed.    

(2) In the terminal prompt of the Anaconda,
I input conda install pytorch=1.1.0 torchvision=0.3.0 cudatoolkit=9.0 –c pytorch.    

However, Anaconda prompt gives the following error    

**Error messages**

UnsatisfiableError: The following specifications were found to be incompatible with the existing python installation in your environment:    

Specifications:

Your python: python=3.8    


If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow not available for the python version you are constrained to. Note that conda will not change your python version to a different minor version unless you explicitly specify that.    

The following specifications were found to be incompatible with each other:

I got solved this issue as follows.


Open Anaconda Powershell Prompt by searching it on the start menu.
then run conda install -c anaconda tensorflow-gpu command.
it may be asked to your acceptance.


finally tensorflow-gpu listed on the installed list.
