Attributeerror: module yaml has no attribute fullloader [SOLVED]

If you are encountering this attributeerror: module yaml has no attribute fullloader error message and you don’t know how to fix it. Don’t worry, because in this article we are going to discuss in detail the solutions.

Continue to read on and discover the solution that may help you to fix the error attributeerror: module ‘yaml’ has no attribute ‘fullloader’ that you are facing right now.

Before we dive into the solution, let us first understand what the error means.

What is “attributeerror: module ‘yaml’ has no attribute ‘fullloader'” error?

AttributeError: module 'yaml' has no attribute 'FullLoader'

The attributeerror: module yaml has no attribute fullloader error message indicates that the module ‘yaml’ doesn’t have the fullloader attribute.

Another thing is that, probably because of an older pyYAML library that you have installed in your system, that doesn’t support the attribute fullloader that you needed.

The reason why this error occurs may be due to a typo in your code or an outdated version of the ‘yaml’ module.

In addition to that, the fullloader attribute is only available in PyYAM version 5.1 and later. Version 5.1 was released on March 13, 2019, so that’s why the older version of pyYAML doesn’t have the fullloader attribute.

Furthermore, the ‘yaml’ module is commonly used in Python for parsing and serializing YAML data.

Solution for “attributeerror: module ‘yaml’ has no attribute ‘fullloader'” error

Here are the possible solutions that will help you fix this error attributeerror: module ‘yaml’ has no attribute ‘fullloader’.

Solution 1: Update yaml module

Updating the ‘yaml’ module to the latest version can fix this error. To upgrade the YaML module, use the following command:

pip install –upgrade pyyaml

pip install -U PyYAML

If you are using Python 3 use the following commands:

pip install –upgrade pyyaml

pip3 install -U PyYAML

import yaml

with open('file.yaml', 'r') as file:
    data = yaml.full_load(file)

By upgrading the module, you should be able to use the fullloader method without getting the attributeError and you can run your Python code perfectly!

Note: When PyYAML is already installed in your system, check the alignment of the file you are trying to parse.

Solution 2: Check the code

The error usually exists because of typos, so it is important to check your code for any typos or syntax errors.

Solution 3: Use SafeLoader

When you still encounter the same error after updating PyYAML, you should try SafeLoader instead of the FullLoader. The SafeLoader is a secure to use and more efficient restrictive YAML parser.

Also, it can be able to load most YAML files. You can use the following code to load a YAML file with the SafeLoader:

import yaml

with open("file.yaml", "r") as f:
    data = yaml.load(f, Loader=yaml.SafeLoader)

By using the SafeLoader, you should be able to load your YAML file without encountering the “AttributeError: module ‘yaml’ has no attribute ‘FullLoader‘” error.

Note: If you have written in your code “file.txt” instead of “file.yaml,” it doesn’t matter as long as you’ve written the same in your Python script.
