TypeError: load() missing 1 required positional argument: ‘Loader’ in Google Colab

We Are Going To Discuss About TypeError: load() missing 1 required positional argument: ‘Loader’ in Google Colab. So lets Start this Python Article.

TypeError: load() missing 1 required positional argument: ‘Loader’ in Google Colab

  1. How to solve TypeError: load() missing 1 required positional argument: 'Loader' in Google Colab

    Now, the load() function requires parameter loader=Loader.
    If your YAML file contains just simple YAML (str, int, lists), try to use yaml.safe_load() instead of yaml.load().
    And If you need FullLoader, you can use yaml.full_load().
    Starting from pyyaml>=5.4, it doesn't have any discovered critical vulnerabilities, pyyaml status.

    yaml.safe_load() should always be preferred unless you explicitly need
    the arbitrary object serialization/deserialization provided in order
    to avoid introducing the possibility for arbitrary code execution.
    More about yaml.load(input) here.

Solution 2

Found the problem.
I was installing pandas_profiling, and this package updated pyyaml to version 6.0 which is not compatible with the current way Google Colab imports packages.
So just reverting back to pyyaml version 5.4.1 solved the problem.

For more information check versions of pyyaml here.
See this issue and formal answers in GitHub

##################################################################
For reverting back to pyyaml version 5.4.1 in your code, add the next line at the end of your packages installations:

!pip install pyyaml==5.4.1

It is important to put it at the end of the installation, some of the installations will change the pyyaml version.

To Solve TypeError: load() missing 1 required positional argument: ‘Loader’ Error Here error is mentioning that your load() function is required param loader=Loader. So That you need to use safe_load() instead of load(). Second solution is Here pyyaml latest version 6.0 is not compatible with the current way Google Colab imports packages. So just downgrade pyyaml version to 5.4.1 which is compatible with the current way Google Colab imports and It will solve your error. use this command to downgrade pyyaml
and When im loading texthero package i got this error after i install pyyaml version 5.4.1 after i restart google colab i
rectify that Error

Ans:- !pip install pyyaml==5.4.1
