Hello Serg,
Well, Datalore currently uses Python 3.8.7, and although you can install or build any specific version you want since you have a sudo access on the agent, I would not recommend doing this due to the following reasons:
- it would be somewhat hard to configure the notebook to use the alternate version
- such configuration will be required each time you start the computation, since the machine is always created with the default image
Why would you want to downgrade Python?
