Can you please try this locally:
Replace the Line 12 in rasa_core/setup.py with:

with io.open('README.md', encoding='utf-8') as f:
    readme = f.read()

It seems, windows is assuming the wrong encoding.

I cloned the repo and first run pip install -r requirements.txt. Now I get the following:

Could not find a version that satisfies the requirement tensorflow==1.1.0 (from -r requirements.txt (line 14)) (from versions: 1.2.0rc2, 1.2.0, 1.2.1, 1.3.0rc0, 1.3.0rc1, 1.3.0rc2, 1.3.0, 1.4.0rc0, 1.4.0rc1, 1.4.0)
No matching distribution found for tensorflow==1.1.0 (from -r requirements.txt (line 14))

Didn't have any issues when installing rasa-core (0.7.6) on the same machine in virtualenv.

Any update or workaround on this? I am facing the same issue. Operating System : Windows 7,64 bit.

@PreranaPolekar I am simply using an older version from a month ago for now. Hopefully this will be fixed in a future version. Try pip install rasa_core==0.7.6.

[PreranaPolekar]

I used tensorflow cpu only version, downgraded to Python 3.5 to get all pieces work together.

[tmbo]

I think there is just no tensorflow version for the combination of windows+python3.5+tensorflow==1.1.0
I'd suggest updating to python 3.6

Let me know if there are still issues with this.
