运行med2image脚本时遇ImportError，求解决方法

Hey there! Let's work through that ImportError you're hitting with med2image version 1.1.1. Here are the most common fixes to try:

1. Verify you're using the correct Python environment #

It's super easy to install packages in one environment (like a global Python or a virtual env) and run your script in another—this mismatch is a top cause of ImportErrors.

• Check which Python version you're running your script with:

  python --version  # or python3 --version, depending on your setup
  

• Check where med2image is installed:

  pip show med2image  # or pip3 show med2image
  

Look for the "Location" field in the output—this path should match the site-packages directory of the Python version you're using to run your script. If not, activate the correct virtual environment or reinstall med2image in the environment you're working in.

2. Reinstall med2image and its dependencies #

Sometimes the initial installation gets corrupted, or required dependencies fail to install properly. Force a fresh reinstall to ensure everything is set up correctly:

pip install med2image==1.1.1 --force-reinstall --no-cache-dir

The --no-cache-dir flag ensures you pull fresh copies of the package and its dependencies, skipping any potentially broken cached files.

3. Install missing required dependencies explicitly #

med2image v1.1.1 relies on libraries like pydicom, numpy, Pillow, and SimpleITK. If any of these didn't install during the initial setup, you'll get an ImportError. Install them directly with:

pip install pydicom numpy pillow SimpleITK

Then try running your script again.

4. Double-check your import statement #

Make sure your script uses the correct import syntax for med2image v1.1.1. The standard import looks like this:

from med2image import med2image

If you're trying to import a specific submodule, confirm it exists in this older version—module structures can change between releases.

5. Fix permission-related installation issues #

If you installed med2image system-wide without admin rights, some files might not have been installed properly. Try installing it to your user directory instead:

pip install --user med2image==1.1.1

This avoids permission hurdles and ensures the package is placed in a location your user account can access.
