pandas data frame to_parquet - Don't know how to convert data type: Int64

615 Views Asked by At

Does anyone know if the issue in the title has been solved ? The issue is that pandas needs a column to be of type Int64 (not int64) to handle null values, but then trying to convert the data frame to a parquet file gets this error: Don't know how to convert data type: Int64

If not solved, is there a known workaround ?
