Pandas ValueError: Non-numeric Value Encountered During Calculation

This error occurs when Pandas encounters a non-numeric value in a calculation where numeric values are expected. The error message suggests that the code is trying to convert a non-numeric value to a float using the 'float()' function, but the value cannot be converted because it is not a valid numeric value. This could be caused by a variety of issues, such as missing or corrupted data, unexpected data formats, or errors in data processing or manipulation.
