16.11.2018 · DataFrame.astype() method is used to cast a pandas object to a specified dtype. astype() function also provides the capability to convert any suitable existing column to categorical type. DataFrame.astype() function comes very handy when we want to case a particular column data type to another data type.
17.11.2021 · Solution 1. df ['a'] returns a Series object that has astype as a vectorized way to convert all elements in the series into another one. df ['a'] [1] returns the content of one cell of the dataframe, in this case the string '0.123'. This is now returning a str object that doesn’t have this function. To convert it use regular python instruction:

The root issue is confusion of Python lists and NumPy arrays, which are different data types. NumPy methods that are invoked as np.foo(array) usually won't complain if you give them a Python list, they will convert it to an NumPy array silently. But if you try to invoke a method contained in the object, like array.foo() then of course it has to have the appropriate type already.

You can't modify the dtype of a slice only. When you do. images[0:5] = images[0:5].astype(numpy.float32) images[0:5].astype(numpy.float32) creates a float copy of your slice, but the result is converted back to int when assigned back to the images slice since images is of dtype int.
