Task:Downgrade NumPy from 2.2.6 to 1.26.4 to restore compatibility with opencv-python==4.9.0.80 and ensure the environment matches

[Anbukannadhasan]

Goal

We are moving back to NumPy 1.26.4 because the newer version (2.2.6) is not compatible with OpenCV 4.9.0.80. By switching to the older NumPy version, we ensure that OpenCV works correctly without any import or compatibility errors. This change restores the environment to a stable, working state.
