Iloc._setitem_with_indexer(indexer, value, self.name)įile "C:\Users\SHUBHAM SAYON\PycharmProjects\Finxer\venv\lib\site-packages\pandas\core\indexing.py", line 1732, in _setitem_with_indexer The above exception was the direct cause of the following exception:įile "C:\Users\SHUBHAM SAYON\PycharmProjects\Finxer\Errors\ValueError-array_sequence.py", line 7, in įile "C:\Users\SHUBHAM SAYON\PycharmProjects\Finxer\venv\lib\site-packages\pandas\core\indexing.py", line 723, in _setitem_ TypeError: float() argument must be a string or a number, not 'list' Output = pd.DataFrame(data=], columns=, index=) Now, consider the following example that leads to the occurrence of the ValueError: You need to import the Pandas library to utilize it. In Python, Pandas is an open-source library that provides high performance with easy-to-use data structures and data analysis tools. ] Solution 2: Dealing with Pandas Library So, you must ensure that the first dimension also has 4 elements. As this is a 2D array having 4 elements in the second dimension. Solution: To eliminate the occurrence of the above error, you have to rectify the shape of the array. In this case, has a dimension of 3, while has dimension 4. The detected shape was (2,) + inhomogeneous part.Įxplanation: Here, the ValueError occurred because the array improper dimensions, i.e. The requested array has an inhomogeneous shape after 1 dimensions. ValueError: setting an array element with a sequence. Output: Traceback (most recent call last):įile "C:\Users\SHUBHAM SAYON\PycharmProjects\Finxer\Errors\ValueError-array_sequence.py", line 4, in Solution 1: Using Proper Array DimensionsĬonsider the following example where we have a certain NumPy array with dimensions as shown below. Now that you know what ValueError is let’s look at the different ways to solve ValueError: setting an array element with a sequence. If you want to learn more about the dimensions of arrays in Python, please refer to this tutorial. The number of indices required to specify an individual array element is its dimension. Note: The number of elements in each dimension of an array is known as its shape.

The error also occurs when you work with the NumPy library, and the NumPy array is not in sequence.

An array does not have a proper shape, i.e., a multidimensional array has improper dimensions at different levels.

The ValueError: setting an array element with a sequence occurs when: e.g., when you define an integer array and insert the string values.

In Python, the ValueError generally gets raised when a function gets the argument of the right type yet an improper value.

In this article, we will look at how you can set an array element with a sequence, and then we will also learn the ways to solve the error – “ ValueError: setting an array element with a sequence“.
