install tensorflow with specific version on Anaconda

Question

Tensorflow has multiple versions, if I want to install a specific version in Anaconda, which command should I use.

Answer 1

I find the existing answers unsatisfying, as the OP asked specifically about Anaconda but the answers are just pip installs.

You can list the available versions for install doing

conda search tensorflow-gpu

which should give you some output that looks like

Loading channels: done
# Name                       Version           Build  Channel             
tensorflow-gpu                 1.4.1               0  pkgs/main           
tensorflow-gpu                 1.5.0               0  pkgs/main           
tensorflow-gpu                 1.6.0               0  pkgs/main           
tensorflow-gpu                 1.7.0               0  pkgs/main           
tensorflow-gpu                 1.8.0      h7b35bdc_0  pkgs/main           
tensorflow-gpu                 1.9.0      hf154084_0  pkgs/main           
tensorflow-gpu                1.10.0      hf154084_0  pkgs/main           
tensorflow-gpu                1.11.0      h0d30ee6_0  pkgs/main           
tensorflow-gpu                1.12.0      h0d30ee6_0  pkgs/main           
tensorflow-gpu                1.13.1      h0d30ee6_0  pkgs/main           
tensorflow-gpu                1.14.0      h0d30ee6_0  pkgs/main           
tensorflow-gpu                1.15.0      h0d30ee6_0  pkgs/main           
tensorflow-gpu                 2.0.0      h0d30ee6_0  pkgs/main           
tensorflow-gpu                 2.1.0      h0d30ee6_0  pkgs/main           
tensorflow-gpu                 2.2.0      h0d30ee6_0  pkgs/main

Then you can select your version by passing it to the install command, for example:

conda install tensorflow-gpu==2.0.0

Note this will work the same for tensorflow (i.e. not the GPU version), just change the package name accordingly.

If you use YAML environment configuration files, you can do the same thing:

# environment.yml
name: my_conda_env
channels:
  - conda-forge
dependencies:
  - tensorflow-gpu=2.0.0

Create your environment with command:

conda env create -f environment.yml

or if you change the version of an already created environment:

conda env update -f environment.yml
