当python出现
“ Attempt to start a new process before the current process
This probably means that you are on Windows and you have
forgotten to use the proper idiom in the main module:
if __name__ == '__main__':
freeze_support()
...
The "freeze_support()" line can be omitted if the program
is not going to be frozen to produce a Windows executable.”
这是因为多进程原因，解决办法，在你使用多进程的模块前添加 if __name__ == '__main__':
例如：
detector = MtcnnDetector(model_folder='model', ctx=mx.cpu(0), num_worker = 4 , accurate_landmark = False)
img = cv2.imread('test.jpg')
# run detector
results = detector.detect_face(img)
if results is not None:
total_boxes = results[0]
points = results[1]
# extract aligned face chips
chips = detector.extract_image_chips(img, points, 144, 0.37)
for i, chip in enumerate(chips):
cv2.imshow('chip_'+str(i), chip)
cv2.imwrite('chip_'+str(i)+'.png', chip)
draw = img.copy()
for b in total_boxes:
cv2.rectangle(draw, (int(b[0]), int(b[1])), (int(b[2]), int(b[3])), (255, 255, 255))
for p in points:
for i in range(5):
cv2.circle(draw, (p[i], p[i + 5]), 1, (0, 0, 255), 2)
cv2.imshow("detection result", draw)
cv2.waitKey(0)if __name__ == '__main__':
detector = MtcnnDetector(model_folder='model', ctx=mx.cpu(0), num_worker = 4 , accurate_landmark = False)
img = cv2.imread('test.jpg')
# run detector
results = detector.detect_face(img)
if results is not None:
total_boxes = results[0]
points = results[1]
# extract aligned face chips
chips = detector.extract_image_chips(img, points, 144, 0.37)
for i, chip in enumerate(chips):
cv2.imshow('chip_'+str(i), chip)
cv2.imwrite('chip_'+str(i)+'.png', chip)
draw = img.copy()
for b in total_boxes:
cv2.rectangle(draw, (int(b[0]), int(b[1])), (int(b[2]), int(b[3])), (255, 255, 255))
for p in points:
for i in range(5):
cv2.circle(draw, (p[i], p[i + 5]), 1, (0, 0, 255), 2)
cv2.imshow("detection result", draw)
