Saya belajar membangun GUI untuk python di PyQt5. Saya mendapat program yang menampilkan webcam dengan deteksi wajah di GUI dengan fungsi mulai dan berhenti menggunakan opencv dan pyqt5. Namun kesalahan berikut terjadi -
mayank@beware-hoax:~/PythonProjects/gui/pyqt5/pyqt5_face_detection$ source /home/mayank/anaconda3/bin/activate
