pip could not find tensorflow 2.0 or 2.1-CodePudding

Silly me to ask such a question (asked here as well 1, 2 ). I tried to install TensorFlow 2.0 or 2.1 on a Ubuntu system for mask-rcnn package, but pip could not find the version of TensorFlow that I desperate need. Could you please let me know why pip could not find tf2.0 or tf2.1? Then how to install tf2.0 or tf2.2?

albert@GIGABYTE:~$ pip install tensorflow==2.0

CodePudding user response：

tensorflow 2.0 and tensorflow 2.1 require Python 2.7 and 3.4-3.7 but not higher. Your Python seems to be higher version (from the list of tensorflow versions I think you use 3.8). Either downgrade Python or use higher version of tensorflow.
