title: Unable to install tensorflow using conda with python 3.8
body: <p>Recently, I upgraded to Anaconda3 2020.07 which uses python 3.8. In past versions of anaconda, tensorflow was installed successfully. Tensorflow failed to be installed successfully in this version.</p>
  <p>I ran the command below;</p>
  <pre><code>conda install tensorflow-gpu
  </code></pre>
  <p>The error message that I received is shown below;</p>
  <pre><code>UnsatisfiableError: The following specifications were found
  to be incompatible with the existing python installation in your environment:
  
  Specifications:
  
    - tensorflow-gpu -&gt; python[version='3.5.*|3.6.*|3.7.*|&gt;=3.7,&lt;3.8.0a0|&gt;=3.6,&lt;3.7.0a0|&gt;=3.5,&lt;3.6.0a0|&gt;=2.7,&lt;2.8.0a0']
  
  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 your CUDA driver:
  
    - feature:/win-64::__cuda==11.0=0
  
  Your installed CUDA driver is: 11.0
  </code></pre>
  <p>Is there a conda command with the right parameters to get tensorflow installed successfully?</p>
