Question

How can you downgrade the protobuf package to version 3.20.x or lower?

A) pip install protobuf==3.20.x
B) pip downgrade protobuf==3.20.x
C) pip uninstall protobuf && pip install protobuf==3.20.x
D) pip install --upgrade protobuf==3.20.x

Answer 1

To downgrade the protobuf package to version 3.20.x or lower, use 'pip install protobuf==3.20.x' or 'pip uninstall protobuf && pip install protobuf==3.20.x' to uninstall the current version first. Option C is the most reliable.

Step-by-step explanation:

To downgrade the protobuf package to version 3.20.x or lower using pip, you can use the command:

pip install protobuf==3.20.x

This assumes that you know the specific 3.20.x version you want to install. If you want pip to handle the uninstallation of the current version before installing the older version, you can run:

pip uninstall protobuf && pip install protobuf==3.20.x

Option C from the ones you've provided is the most complete method, as it ensures that the currently installed protobuf is removed before installing the older version. Both of these commands should be executed in the terminal or command prompt.
