instruct prompt

Load a CSV file into a pandas DataFrame and replace the NaN values in numeric columns with the mean of the corresponding column. The resulting DataFrame is returned. If an empty csv is passed, an empty DataFrame is returned.
The function should raise the exception for: FileNotFoundError: If csv_file does not exist.
The function should output with:
    pd.DataFrame: A pandas DataFrame with the processed data.
You should write self-contained code starting with:
