  ERROR: Cannot install -r requirements.txt (line 17) and tensorboard==2.1.0 because these package versions have conflicting dependencies.
  
  The conflict is caused by:
      The user requested tensorboard==2.1.0
      tensorflow 1.15.4 depends on tensorboard&lt;1.16.0 and &gt;=1.15.0
  
  To fix this you could try to:
  1. loosen the range of package versions you've specified
  2. remove package versions to allow pip attempt to solve the dependency conflict
