Resuelva instalando openCV-Python explícitamente primero usando !pip install opencv-python==4.2.0.34 antes de ejecutar !pip install imgaug Como la versión anterior de opencv-python no requiere compilación de ruedas.

intente usar la versión anterior de python. por ejemplo, python3.7

Tuve el mismo problema, todo salió bien:
pip install --upgrade pip setuptools wheel0
También me sucedió mientras descargaba pip install opencv-python Simplemente vaya a las preferencias, vaya al intérprete de python y luego verifique el paquete de ruedas y elimínelo haciendo clic en él y presionando la marca menos junto a la marca de agregar. Este error se debe a que, para descargarlo, el paquete primero debe generar miles de dependencias para las ruedas, ya que opencv es un paquete grande. Si desinstala las ruedas, no es necesario que creen dependencias. Tenga en cuenta que desinstalar ruedas no afectará nada en el código . Tengo una Mac y uso pycharm como IDE, así que no estoy seguro de si funciona en otros dispositivos.
Esta es una imagen del intérprete que está después de desinstalar las ruedas.

Si está usando Raspberry pi, use el comando pip install opencv-python==4.5.3.56 , luego actualice numpy usando pip install -U numpy y luego instale el paquete que necesita instalar que tiene dependencia de OpenCV.
