📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The session aimed to troubleshoot and resolve various issues encountered during DataFrame manipulation using Pandas and NumPy in Python.

Key Activities

  • Investigated potential causes for errors when adding new columns to a DataFrame, focusing on conflicts with NumPy and memory issues.
  • Explored solutions for unusual errors in Pandas DataFrame column creation, including checks for corrupted data and library conflicts.
  • Addressed compatibility issues between NumPy 2.x and libraries compiled with NumPy 1.x by downgrading NumPy and rebuilding the environment.
  • Updated the Pandas stack method to avoid FutureWarning by including the future_stack=True parameter.
  • Implemented robust handling of NaN values in DataFrame indexing using idxmax().
  • Utilized Pandas for selecting rows with the latest timestamp for each group, simplifying the process with groupby and transform.
  • Resolved SettingWithCopyWarning and FutureWarning in Pandas by using .loc for DataFrame assignments.

Achievements

  • Successfully resolved compatibility issues between Pandas and NumPy.
  • Improved DataFrame manipulation techniques to avoid common warnings and errors.

Pending Tasks

  • Continuous monitoring for any further compatibility issues with future library updates.
  • Review and optimize DataFrame operations for performance improvements.
