Managing large datasets with pandas is a pretty common issue. As a result, a lot of libraries and tools have been developed to ease that pain. Take, for instance, the pydatatable library mentioned…

Summary

  • Optimizing pandas memory usage by the effective use of datatypes Managing large datasets with pandas is a pretty common issue.
