To solve this error, you can follow the steps below:

1. Check your Python version: The scikit-image package requires a Python version of 3.5 or higher.

If you are using a version lower than 3.5, you need to upgrade your Python version. 2.

Check your virtual environment: If you are working in a virtual environment, make sure that the scikit-image package is installed in that environment. To check if the package is installed, activate your virtual environment, and run the command “pip show scikit-image” in the terminal.

If the package is not installed, install it using “pip install scikit-image”. 3.

Check your IDE: If you are using an IDE, make sure that the scikit-image package is installed in the IDE. You can install the package by using the terminal in the IDE or using the package manager.

4. Reinstall or upgrade the package: If the scikit-image package is already installed but you still encounter the error, try reinstalling the package or upgrading it to the latest version.

Installing scikit-image (skimage) on Windows:

Scikit-image is a popular Python package for image processing and analysis. To install scikit-image on Windows, you can follow the steps below:

1.

Open the Command Prompt (CMD) or PowerShell: To open the Command Prompt, press the Windows key + R, type “cmd”, and press enter. To open PowerShell, press the Windows key + X, and select “Windows PowerShell (Admin)”.

2. Create a virtual environment: Create a new virtual environment for your Python project using the command “python -m venv myenv” or “py -m venv myenv”.

Make sure to replace “myenv” with the name of your virtual environment. 3.

Activate the virtual environment: Activate the virtual environment using the command “myenvScriptsactivate” in the CMD or “myenvScriptsActivate.ps1” in the PowerShell. 4.

Install scikit-image: Use the command “pip install scikit-image” to install the scikit-image package in your virtual environment. 5.

Check if the package is installed: To check if the package is installed, use the command “pip show scikit-image”. Alternative Installation of scikit-image:

If you are using Debian or a Linux-based system, the installation process for scikit-image might be different.

In some cases, you might encounter a permissions error while installing the package. To solve this error, you can install the “build-essential” package using the command “apt-get install build-essential”.

This package contains the necessary tools to build and install Python packages.
