No Module Named '_ctypes' Issue in Python 3: Exploring a Solution

In Python 3, users may encounter an ImportError when using Value from the multiprocessing module, specifically when they receive "No module named '_ctypes'". This issue arises due to missing dependencies.

To resolve this problem, users should install libffi-dev and reinstall Python 3. This step ensures that Python has the necessary dependencies to successfully import the _ctypes module.

Installation Instructions:

Depending on the operating system, the installation commands will vary:

RHEL/Fedora:

sudo yum install libffi-devel

or

sudo dnf install libffi-devel

Debian/Ubuntu:

sudo apt-get install libffi-dev

After installing libffi-dev, proceed to reinstall Python 3. This action will overwrite any existing installation and ensure that it is properly configured with the required dependencies.

Once Python 3 is reinstalled, the ImportError: No module named '_ctypes' issue should be resolved, and users can successfully utilize the Value variable in the multiprocessing context.
