when I run pip install keras numpy matportlib mnist in google colab it shows:
Looking in indexes: https://pypi.org/simple, https://us-python.pkg.dev/colab-wheels/public/simple/
Requirement already satisfied: keras in /usr/local/lib/python3.7/dist-packages (2.8.0)
Requirement already satisfied: numpy in /usr/local/lib/python3.7/dist-packages (1.21.6)
ERROR: Could not find a version that satisfies the requirement matportlib (from versions: none) ERROR: No matching distribution found for matportlib
How I can fix this error?
