Aug 27, 2017 · But astype() fails: day.astype('timedelta64[h]') # AttributeError: 'Timedelta' object has no attribute 'astype' The example in the documentation doesn't actually use pd.Timedelta(), and that seems to be part of the issue.
AttributeError is raised in Python when you attempt to call the attribute of an object whose type does not support the method. For example, attempting to utilize the append () method on a string returns an AttributeError as lists use the append() function and strings don’t support it. Example: # A set of strings names = {"John", "Rashi"}
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.
It will display the built-in functions, exceptions, and other objects as a list.>>>dir(__builtins ) ['ArithmeticError', 'AssertionError', 'AttributeError', ...

y =y.values().astype(int) y is a list and lists do not have a method values() (but dictionaries and DataFrames do). If you would like to convert y to a list of integers you can use list comprehension: y = [int(x) for x in y] Or alternatively use map (but I'd prefer the list comprehension): y = list(map(int, y))

AttributeError: 'list' object has no attribute 'dtype'. I have trouble with Bollinger Band algorithm. I want to apply this algorithm to my time series data.
I would suggest using. data = np.array (data, dtype=np.float32) so that the type of an array is known to NumPy at once. This avoids unnecessary work where you first create an array and then cast it to another type. NumPy recommends using dtype objects instead of strings like "float32". Share.
