Traceback. Not sure why it says setting an array element with a sequence. ![]() Xi = np.concatenate((log(np.array(), randn(N)) we can fix this error by matching the data-type of value and array and then assign it as element of array. Here we have seen that this error is cause because we are assigning array as a element to array which accept string data-type. The error also occurs when you work with the NumPy library, and the NumPy array is not in sequence. ValueError: setting an array element with a sequence. Yvec = max(0, yvec + dt * (t4*xvec*yvec - t3*yvec) + sqrt(dt) * sy * u) The ValueError: setting an array element with a sequence occurs when: An array does not have a proper shape, i.e., a multidimensional array has improper dimensions at different levels.
