ImportError: cannot import name 'MyLibrary'

I watched a tutorial which was coded in Python about OpenCV. I get an error when I try to import a class. The error is below.

 Traceback (most recent call last):
  File "webstreaming.py", line 1, in <module>
    from pyimagesearch.motion_detection import SingleMotionDetector
ImportError: cannot import name 'SingleMotionDetector' from 'pyimagesearch.motion_detection' (/home/pi/Desktop/Denemeler/pyimagesearch/motion_detection/__init__.py)

Here is my directory tree.

.
├── pyimagesearch
│   ├── __init__.py
│   └── motion_detection
│       ├── __init__.py
│       └── singlemotiondetector.py
├── templates
│   └── index.html
└── webstreaming.py

I checked stackoverflow but none of the answers worked for me. Thanks.

When a regular package is imported, this init.py file is implicitly executed, and the objects it defines are bound to names in the package’s namespace.

Since __init__.py doesn't have module imports, We'll have to manually import the required sub modelues from the respective file. SingleMotionDetector is in singlemotiondetector.py, the import should look like

from pyimagesearch.motion_detection.singlemotiondetector import SingleMotionDetector
