Best answer by mohammedkh 29 April , Try to comment out the third line and add the following to see what the value actually is while the workspace is running:. If you're happy to ignore cases where the list doesn't exist you could use. Or you could just test to exclude prior to the pythoncaller. I'm guessing you have more than one feature? Do they all have a list of values, or does one or several of them not have a list value?

Screen Shot at Thank you in advance. Yes, I get that. But I just followed the fastai notebook. Why would this happen? Did I not download the images correctly? It may be worth to check whether you have images in the folder where path is pointing. You can do something like [f for f in path. If there are not images, of if path is not a proper path, then it means there was problem higher in the loading of images. I had the same issue and the solution was an incomplete creation of the bears folder, just delete the folder and rerun the cell blocks to create them properly. However running the cells again never properly remade it or added the other 2 folders and was returning a non type, super weird, took me like a week to notice after I was comparing running it in a fresh environment just by chance and noticed that the folders where off and looking through the files presuming the error came from the code block above the error containing mkdir.

It is an object that can record and store operations performed on it as a "script" that can be replayed.

Explore your training options in 10 minutes Get Started. With Python, you can only iterate over an object if that object has a value. This is because iterable objects only have a next item which can be accessed if their value is not equal to None. In this guide, we talk about what this error means and why you may encounter it. We walk through an example to help you solve how to solve this common Python error. For an object to be iterable , it must contain a value.

For an object to be iterable in Python, it must contain a value. Some of the most common sources of None values are:. In the above example, mylist is attempted to be added to be iterated over. This can help ensure that only objects that have a value are iterated over, which avoids the error. Here, a check is performed to ensure that mylist is not None before it is iterated over, which helps avoid the error. Managing errors and exceptions in your code is challenging. It can make deploying production code an unnerving experience.

Nonetype object is not iterable

None and iterables are distinct types of objects in Python. None is the return value of a function that does not return anything, and we can use None to represent the absence of a value. An iterable is an object capable of returning elements one at a time, for example, a list. This tutorial will go through the error in detail. We will go through an example scenario and learn how to solve the error. TypeError occurs in Python when you perform an illegal operation for a specific data type. You cannot iterate over an object that is not iterable. Another example of a non-iterable object is an integer. An iterable is a Python object that you can use as a sequence.
