Before we begin our tutorial, have a quick overview of Python and AttributeError.

Python is one of the most popular programming languages. It is used for developing a wide range of applications. It is a high-level programming language that is usually used by developers nowadays due to its flexibility.

What is AttributeError?

An attributeerror is an error that appears in our Python codes when we try to access an attribute of a non-existent object. In addition, this occurs when we attempt to perform non-supported operations.

Now that we understand this error and even what Python and an AttributeError are, let’s move on to our “how to fix this error” tutorial.

How to solve “type object ‘callable’ has no attribute ‘_abc_registry’” in Python

Time needed: 2 minutes

Here is the step-by-step guide to resolve the Python error attributeerror: type object 'callable' has no attribute '_abc_registry'.

  1. Upgrade the Python version.


    The first step is to upgrade your Python version to the latest version.

    To upgrade your Python version, go to the Python official website and download the latest version of Python.

  2. Use the typing.Callable[…, Any].


    Instead of using typing.Callable, use the typing.Callable[..., Any] if you can’t upgrade your Python version.

  3. Use the built-in callable() function.


    You must avoid using typing.Callable to check whether an object is callable or not. Instead, use the built-in callable() function.

  4. Check for version compatibility.


    Always check for compatibility of your libraries with the version of Python you’re using. For example, you have a library that relies on typing.Callable, make sure that it is compatible with your Python version.

Alternative Solution

If the above solution does not work, try this alternative solution:

✮ Uninstall the typing module.

To uninstall the typing module, open your command prompt, then enter the command pip uninstall typing.

After inputting the pip uninstall typing command, results will come out, and this question will also appear (Proceed (Y/n)?). Once that appears, just type Y, then click the Enter key.

Example:

C:\Users\pies-pc1>pip uninstall typing
Found existing installation: typing 3.7.4.3
Uninstalling typing-3.7.4.3:
  Would remove:
    c:\users\path\path\lib\site-packages\typing-3.7.4.3.dist-info*
    c:\users\path\path\lib\site-packages\typing.py
Proceed (Y/n)? y
  Successfully uninstalled typing-3.7.4.3

Commands you might need

  • pip list

    This command will display all the packages installed on your system, including their versions.

    Use the !pip list command instead of pip list if you use Jupyter Notebook. However, if you’re using Anaconda, use the command conda list.
  • pip install --upgrade pip

    Use this command to upgrade the pip package manager to its newest version. If your pip is already in the latest version, this will come out: “Requirement already satisfied.”
  • pip --version

    Use this command to check what version of pip you have or have installed on your system.

    Note: If you’re using Jupyter notebook, use the command !pip --version.
  • python --version

    Use this command to check what version of Python you have.

    Note: If you’re using Jupyter notebook, use the command !python --version. However, if you’re using Anaconda, just use the command python --version.
  • pip show (package)

    Use this command to display information about a module or package, including its location and version. For example, pip show typing.

    Note: If you’re using Jupyter Notebook, use the command !pip show typing.

Conclusion

In conclusion, the Python error attributeerror: type object 'callable' has no attribute 'abc_registry' can be easily solved by either upgrading your Python version or uninstalling the typing module.
