module collections has no attribute mutablemapping


Attributeerror: module collections has no attribute mutablemapping error is because of internal code changes in the 3.10 version. If you are using any syntax related to the collections module which is compatible with the 3.9 version over the python 3.10-based python environment, you will get this error. In this article, we will explore the best ways to fix module collections has no attribute mutablemapping error.

Attributeerror: module collections has no attribute mutablemapping ( Solution ) –

There are multiple approaches to fixing these issues. In this section, we will address them one by one.

Solution 1: Downgrading the python version to 3.9 version or less –

Since this error is specific to python 3.10 version. Hence we will downgrade our python version version to 3.9 or any compatible lower version. All you need to install the lower version successfully. It will replace the older python version. It means you do not have to explicitly uninstall the current python version.

python release 3.9 version
python release 3.9 version

Solution 2: Changing the import statement –

Actually, since the internal structure is changed in the 3.10 version so have to use two different ways for importing this mutablemapping module. Here is the syntax difference-

For version 3.10 or above –

from collections.abc import MutableMapping

For version 3.9 or lower –

from collections import MutableMapping

If you want this environment completely dynamic then call the below code.

import collections 
if sys.version_info.major == 3 and sys.version_info.minor >= 10

    from collections.abc import MutableMapping
else 
    from collections import MutableMapping

The above code will check the current python major and minor versions. On the basis of the available configuration, it will flow with the correct syntax. This is a standard way to make code version independent.

`Solution 3: Upgrading related package –

In some scenarios, upgrading the below setup packages along with the requests module, etc has resolved this error. Hence if the above two have not resolved the error completely then firstly we should try these set of commands. After this, we should again try solution 2.

pip install --upgrade pip
pip install --upgrade wheel
pip install --upgrade setuptools
pip install --upgrade requests

Hope now you are able to fix the error collection that has no attribute mutablemapping. In case of any query please comment below.
