It expects whatever you give it to evaluate to a single number, if it doesn't, Numpy responds that it doesn't know how to set an array element with a sequence. you index in nested list, therefore obtain a list and put this list into a cell which holds a float putting a sequence/list into array element ERROR. A numpy array is being created, and numpy doesnt know how to cram multivalued tuples or arrays into single element slots. you convert wyjscie to a list, but this list will be a nested list because original dim is 2d. Then when you try to set a list as the value, it errors out, due to the dtype. X = np.array() #Fail, can't convert the numpy array to fitĪ numpy array is being created, and numpy doesn't know how to cram multivalued tuples or arrays into single element slots. H is a numpy-array with dtypefloat as it's default. If you really want to set a list as the value for the element, the issue is with the dtype of the column, when you create the DataFrame, the dtype gets inferred as float64, since it only contains numeric values. By trying to cram a numpy array length > 1 into a numpy array element: x = np.array() Introduction to Statistics is our premier online video course that teaches you all of the topics covered in introductory statistics.Get started with our course today. Numpy.array() #Fail, can't convert a list into a numpyĢ. an() #Fail, can't convert a tuple into a numpy Numpy.array() #Fail, can't convert a tuple into a numpy When you pass a python tuple or list to be interpreted as a numpy array element: import numpy It can be thrown under various circumstances.ġ. The following example shows how to fix this error in practice. This error typically occurs when you attempt to cram several numbers into a single position in a NumPy array. Means exactly what it says, you're trying to cram a sequence of numbers into a single number slot. In python Valueerror: Setting an Array Element with a Sequence means you are creating a NumPy array of different types of elements in it. ValueError: setting an array element with a sequence. A set is an unordered collection with no duplicate. Sets Python also includes a data type for sets. Note that multiple assignment is really just a combination of tuple packing and sequence unpacking. The Python ValueError: ValueError: setting an array element with a sequence. Sequence unpacking requires that there are as many variables on the left side of the equals sign as there are elements in the sequence.
