Conda Install Downgrade Python Version

I'm trying to downgrade python version of anaconda via conda install python=3.3, but have following error: ~/anaconda3/bin$ ./conda install python=3.3 Fetching package metadata ...

Solution 1:

If you want to set specific version, use it like this:

WARNING: This command will overwrite the default python version system-wise

conda install python=3.6

To create environment with a specific version, you can do:

conda create -n $PYTHON36_ENV_NAME python=3.6 anaconda  # set custom env name

The anaconda at the end allows the env to use all anaconda packages

For more information refere to Anaconda documentation

Solution 2:

You can make environments with other versions of Python using this command:

conda create --name py33 python=3.3
source activate py33

Solution 3:

Very firstly check the current version using command python --version. Then on anaconda prompt type the command conda search python which will list all the python versions available till date. Then from that list select your version and type conda install python=3.5.2 or any of your choice
