CI workflow pylint error

[AryanNanda17]

Currently, all the CI Workflows are failing becuase of this issue:-

Unable to import 'matplotlib.pyplot`

I did a testing PR #212 to verify the issue.

This failure could be due to one of the following reasons:-

• Transitive Dependency Removed: matplotlib was previously installed indirectly via another package that no longer requires it.
• Upstream PyPI Package Changes: Some PyPI packages may have dropped matplotlib as a default dependency or moved it to optional extras.

PR #213 fixes the issue.

PR #213 is merged now which resolves this issue.
