ImportError: Error while finding loader for 'tensorflow' in ENV2

[cvonholly]

When installing all dependencies according to ENV 2, i get the following error:

Using TensorFlow backend.
Traceback (most recent call last):
  File "C:\PATH\Python\Python37\lib\pkgutil.py", line 493, in find_loader
    spec = importlib.util.find_spec(fullname)
  File "C:\PATH\Python\Python37\lib\importlib\util.py", line 114, in find_spec
    raise ValueError('{}.__spec__ is None'.format(name))
ValueError: tensorflow.__spec__ is None

The above exception was the direct cause of the following exception:
