我创建了一个 venv 并尝试安装 tensorflow 1.15 但仍然是同样的错误

Question

Please Help me out. I have installed tensorflow 2.3 globally and am trying to install tensorflow 1.15 but always face this error. I tried uninstalling tensor globally but failed.

(Cardiac) C:\venvCardiac>pip install tensorflow==1.15
Collecting tensorflow==1.15
  ERROR: Could not find a version that satisfies the requirement tensorflow==1.15 (from versions: 2.2.0rc1, 2.2.0rc2, 2.2.0rc3, 2.2.0rc4, 2.2.0, 2.2.1, 2.3.0rc0, 2.3.0rc1, 2.3.0rc2, 2.3.0, 2.3.1, 2.4.0rc0, 2.4.0rc1, 2.4.0rc2, 2.4.0rc3, 2.4.0rc4)

Answer 1

As stated here: https://www.tensorflow.org/install/pip Python3.8 is not compatible with Tensorflow 1.x but only with Tensorflow 2.x.

You should create a new python environment with an older python version (like 3.6.9) and then install Tensorflow 1.15 if that's what you need.

Answer 2

For uninstalling tensorflow:

pip uninstall tensorflow

Upgrade pip using this command:

pip install --upgrade pip

Installing tensorflow 1.15 using this command:

pip install tensorflow==1.15.0
