I am preparing a docker image for Ubuntu 20.04 and due to TensorFlow 2.0 requirement, I need Python 3.7. TensorFlow runs on Python 3.5 to 3.7. Running apt install python3 installs Python 3.8 by default and that breaks my TensorFlow installation.
Is there any way I can get an apt package for Python 3.7 for Ubuntu 20.04? Since it is going to be inside docker image, I don't want to get into the business of downloading Python 3.7 source code and compiling. Putting those commands in Dockerfile will be overwhelming for me. Is there any simpler way of getting Python 3.7 for Ubuntu 20.04?
Running
sudo apt-cache madison python3
returns
python3 | 3.8.2-0ubuntu2 | http://in.archive.ubuntu.com/ubuntu focal/main amd64 Packages
Do you need Ubuntu 20.04? Ubuntu 18.04 comes with Python 3.6, and 3.7 available.
If you do, the deadsnakes PPA has Python 3.5-3.7 for Ubuntu 20.04 (Focal). To add it and install:
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.7
P.s. I'm not a dev and have no experience with Tensorflow so take this with a grain of salt.
Tensorflow 2.2 now supports python 3.8 so problem is solved now.
