How can I solve memory issues with pandas?
You can try optimizing your DataFrame by using data types that consume less memory, like 'category' for categorical data.
What about using chunking to handle large datasets?
Yes, chunking is a great approach! You can read large files in smaller chunks using the chunksize
parameter in pandas.read_csv()
.
Are there any other techniques to reduce memory usage?
You can also drop unnecessary columns, use DataFrame.astype()
to convert data types, and consider using Dask for larger-than-memory datasets.
What is Dask and how does it help with pandas?
Dask is a parallel computing library that integrates with pandas, allowing you to work with larger-than-memory datasets by breaking them into smaller, manageable pieces.
