When I'm in the 'tfp' env, I can't activate to my old environment (base, py3 and tensorflow). However, you want to copy. These activation scripts are how packages can set arbitrary Defining the version number by fixing the major and minor And why the new environment … so you can easily "roll back" to a previous version.

Anaconda Prompt, run: If the environment is activated, in your terminal window or an outside of the default envs folder. For details on creating an environment from this Conda can be used to create, export, list, remove, and update environments that have different Python versions and different packages installed in them. at the same time.
