Hello,

When got TX2 module, installed all software via jetpack, and apt-get install python-opencv, i checked the python-opncv version is 2.4.9, and complied py-faster-rcnn successfully, and I change tool/demo.py:

capture = cv2.VideoCapture(1)
ret, im = capture.read()
im_detect(net, im)
then got this problem as below message:

GHGUI ERROR: V4L/V4L2: VIDIOC_S_CROP
The camera found!

Traceback (most recent call last):
File “demo_video.py”, line 195, in

scores, boxes = im_detect(net, im)

im_orig = im.astype(np.float32, copy=True)
AttributeError: ‘tuple’ object has no attribute ‘astype’

Is somebody can help me?
