Hi Kaviya,

These errors might appear for the following reasons:

Potential Reasons

1. NaN or Inf Values: Your labels might contain NaN (Not a Number) or Inf (Infinity) values, which are considered undefined.
2. Missing Values: There might be missing values in your labels that are not properly handled.
3. Incorrect Data Types: The labels might not be in the expected data type (e.g., they are strings instead of numeric values).
4. Normalization Issue: The normalization process might have introduced undefined values into the labels.
