To rectify this error you need to create an array with an equal number of elements having equal dimensions. The below snippet shows the value error generated due to the use of different dimensions: Solution: Create an Array With an Equal/Same Number of Elements lists and tuples) Intrinsic NumPy array creation functions (e.g. The prominent/main reason which causes this error in Python is using different dimensions while initializing the array. There are 6 general mechanisms for creating arrays: Conversion from other Python structures (i.e. Reason 1: Creating an Array With Different Dimensions Reason 3: Using Different Types of Elements import numpy as np create NumPy array data np.array( 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) Now suppose we attempt to cram two numbers into the first position of the array: attempt to cram values '4' and '5' both into first position of NumPy array data 0 np.array( 4,5) ValueError: setting an array element with a sequence. 1 Answer Sorted by: 1 H is a numpy-array with dtypefloat as it's default.Part of the problem is that np.array(df.A) does not correctly create a 2D array: > np.array(df.A) array(10, 15, 12, 14, 20, 30, 10, 43, dtypeobject) >. The other case when you will get this error is when you are creating a multiple-dimensional NumPy array. Notice that it's dtypeobject, and one of these objects is a list, hence 'setting array element with sequence. For example, mixing int with float or int or float with string. ⢠Solution: Replace a Single Value Into the Array In python Valueerror: Setting an Array Element with a Sequence means you are creating a NumPy array of different types of elements in it. import numpy as np a np.array ( 1, 2, 3, 4, 5, 6) b np.array ( 7, 8, 9)Reshape b to match the shape of abreshaped b.reshape ( (1, 3))Add the two arraysc a + breshaped In this example, we reshape the b array to match the shape of the a array using the reshape () function.Reason 2: Replacing a Single Array Element With an Array.Solution: Create an Array With an Equal/Same Number of Elements.Reason 1: Creating an Array With Different Dimensions.This blog will explore the causes of this error and provide tips to rectify the error: The error occurs when you try to assign a sequence of values (such as a list or tuple) to an array element. So, Numpy can successfully create an array.While working with arrays in Python, you may have encountered the error âValueError: setting an array element/items with a sequenceâ. Here, no error is encountered as all the individual sequences or arrays have two elements each. Np.array(,, ],, , ] ], dtype=int) Explanation This two-dimensional array has individual arrays that have two elements each, This is because the structure of the array is not correct. We can see that when this code is executed, the ValueError is raised. ValueError: setting an array element with a sequence. The detected shape was (1000, 2) + inhomogeneous part. The requested array has an inhomogeneous shape after 2 dimensions. Output Traceback (most recent call last): ValueError: setting an array element with a sequence. Let us see the details of this error and also its solution: : File C:\Users\computers\Downloads\he.py, line 13, in nparray numpy.array(array1,dtypeDatatype) ValueError: setting an array element with a sequence.This error usually occurs when the Numpy array is not in sequence. While programming in Python, especially Numpy a library in Python, programmers encounter an error called ValueError: setting an array element with a sequence. I know this is possible with Pythons list since I can append the new array to list and it will work. Im not sure on how to do this since every time I try I get ValueError: setting an array element with a sequence. and saving it into a NumPy array defining. Im trying to set an element of a Numpy array to be another Numpy array. The requested array has an inhomogeneous shape after 1 dimensions. What is ValueError: setting an array element with a sequence? aarray ( 0.2,linspace (1,60,60), 60.8) ValueError: setting an array element with a sequence. ValueError: setting an array element with a sequence.
