The sys.path manipulation using os.path.dirname three times is fragile and inconsistent with how the existing codebase handles imports. Consider using relative imports or setting up the project with proper package structure instead.

Suggested change

	import sys
	import os
	sys.path.append(os.path.dirname(os.path.dirname(os.path.dirname(__file__))))

Using wildcard imports (from config import *) is discouraged as it pollutes the namespace and makes it unclear what names are being imported. Import only what you need explicitly, e.g., from config import LOG_LEVEL, LOG_FORMAT, CAMERA_INDEX, ROI_SIZE, ....

Suggested change

	from config import *
	from config import (
	LOG_LEVEL,
	LOG_FORMAT,
	CAMERA_INDEX,
	SUCCESS_MESSAGES,
	ERROR_MESSAGES,
	ROI_SIZE,
	FACE_SCALE_FACTOR,
	FACE_MIN_NEIGHBORS,
	EMOTIONS,
	)

There's a potential bug in the cache eviction logic. If the cache reaches max_size and all items have been set but never accessed (all have access_count of 0), the min() function will arbitrarily pick one, but after deletion, if a new key is immediately added with access_count=0, there's no issue. However, there's a logical issue: when checking if len(self.cache) >= self.max_size, it should be >= self.max_size before adding, not after. The current logic is correct for this, but the eviction happens before checking if the key already exists in the cache. If the same key is being updated, this will unnecessarily evict an item. Consider checking if the key exists first before eviction.

This hardcoded absolute path is specific to a user's local machine and will not work for other contributors. Replace with a relative path or a more generic instruction like "cd path/to/project".

Suggested change

	cd "/Users/pankajsingh/Movies/OPENSOURCE PROJECT/Music-Recommendation-Using-Facial-Expressions"
	# From your desired directory, clone the repository (if you haven't already)
	# git clone https://github.com/<your-org-or-user>/Music-Recommendation-Using-Facial-Expressions.git
	# Change into the project directory
	cd path/to/Music-Recommendation-Using-Facial-Expressions
