Could not find a version that satisfies the requirement tensorflow~=1.15.0

I solved the issue by switching to Docker builds.

#1 Added heroku.yml to the root of my project:

    web: Dockerfile
  web: python

#2 pip upgrade happens in the Dockerfile:

FROM python:3.7-slim
RUN pip install --upgrade pip
RUN pip install --no-cache-dir -r requirements.txt

#3 Don’t forget to change the type of your Heroku app:

heroku stack:set container --app YOUR_APP_NAME

This way I was able to control both the Python and the pip version. Prior to moving to the Docker deployments I tried upgrading Python to the latest stack in Heroku (through runtime.txt), but to no avail: pip won’t get upgraded beyond 9.0.x.


Below step will help pip3 install tensorflow==1.5 pip3 install rasa-x --extra-index-url --ignore-installed tensorflow

Looks like the problem is with Python 3.8. Use Python 3.7 instead. Steps I took to solve this.

  1. Created a python 3.7 environment with conda
  2. Installed rasa using pip install rasa within the environment.

Worked for me.

  1. Uninstall python-pip
$ sudo apt remove python-pip
  1. Install Python3-pip
$ sudo apt install python3-pip
  1. Upgrade pip using python3 -m
$ python3 -m pip install --user --upgrade pip
  1. Install rasa using python3-m
$ python3 -m pip install --user rasa

This is cos the version of TF (1.15) that the rasa installer requires is pretty old and isn’t compatible with python 3.8. The solution would be to downgrade python to 3.6 (maybe 3.7) and try again.

TF on it’s own works fine with python 3.8:

pip install

this is what I did on a mac: I already had python3.6 installed with brew

brew link --overwrite python
python3.7 --version
virtualenv -p python3.7 venv
source venv/bin/activate

# then this will work
pip install rasa

is --user equally relevant for a virtualenv what versions are you expecting to arrive at?

I thought this problem is the version of TF being used is related to a specific python version? maybe worth posting your exact env that you were able to install with?

I can confirm your solution did NOT work with a python 3.8 virtual env

you have a typo

I faced the same issue. Solved by using python:3.7.4 and pip:20.0.2
