Fix DatatypeMismatchError

in Arize Phoenix

Solution

DatatypeMismatchError in Phoenix often arises when filtering or comparing columns with incompatible data types (e.g., comparing a string to a number). To fix this, ensure the data types are consistent before applying filters or comparisons, using explicit type conversions if necessary (e.g., converting a string representation of a number to an integer/float using `astype`). Validate your data schema to confirm the correct data types are assigned to each column.
