How to solve TypeError: ‘numpy.float64’ object is not iterable

Posted on February 27, 2023March 1, 2023 By Pythoneo 1 Comment on How to solve TypeError: ‘numpy.float64’ object is not iterable

The error message “TypeError: ‘numpy.float64’ object is not iterable” usually occurs when you try to iterate over a numpy float64 object directly.

To solve this error, you need to ensure that you are not trying to iterate over a single numpy float64 object. Instead, you should iterate over a numpy array or a Python list.

Here is an example of how to fix this error:

How to solve ValueError: setting an array element with a sequence

Posted on February 19, 2023March 1, 2023 By Pythoneo 1 Comment on How to solve ValueError: setting an array element with a sequence

The ValueError: setting an array element with a sequence error typically occurs when you try to assign a sequence (e.g., list, tuple) to an element of a numpy array that expects a scalar value.

To solve this error, you need to make sure that you are assigning a scalar value to the array element, rather than a sequence.

Here are some steps you can take to solve this error:

How to calculate exponential of complex number in Numpy?

Posted on February 13, 2023March 2, 2023 By Pythoneo

In NumPy, you can calculate the exponential of a complex number using numpy.exp. The exponential of a complex number z can be represented as exp(z) = exp(x) * (cos(y) + 1j * sin(y)), where x and y are the real and imaginary parts of the complex number z, respectively.

How to use gradient in Numpy

Posted on February 16, 2022March 2, 2023 By Pythoneo

In NumPy, the gradient of an array can be computed using the numpy.gradient function. This function calculates the gradient of an N-dimensional array, and returns a list of N arrays, each of which gives the gradient along a particular dimension.

Here is an example of how you can use numpy.gradient to calculate the gradient of a 1-dimensional array:
