TypeError: 'value' Must Be a String or Bytes in Python - NumPy Float64 Error

This error occurs when you try to pass a value that is of type 'numpy.float64' to a function or method that expects a string or bytes type.

To resolve this error, you can convert the 'numpy.float64' value to a string using the 'str()' function. Here's an example:

import numpy as np

value = np.float64(3.14)
str_value = str(value)

In this example, 'value' is a 'numpy.float64' value and 'str_value' is a string representation of 'value'. You can then use 'str_value' in functions or methods that expect a string or bytes type.
