Print not work in mxnet

I want to print gt_boxes here

            # for each ground-truth, find the best matching anchor within the particular grid
            # for instance, center of object 1 reside in grid (3, 4) in (16, 16) feature map
            # then only the anchor in (3, 4) is going to be matched
            gtx, gty, gtw, gth = self.bbox2center(gt_boxes)
            shift_gt_boxes = nd.concat(gtx * 0, gty * 0, gtw, gth, dim=-1)
            anchor_boxes = nd.concat(0 * all_anchors, all_anchors, dim=-1)  # zero center anchors
            shift_anchor_boxes = self.bbox2corner(anchor_boxes)
            ious = nd.contrib.box_iou(shift_anchor_boxes, shift_gt_boxes).transpose((1, 0, 2))
            # real value is required to process, convert to Numpy

for example. but the nothing will print when run the code ?
how to print it?

Hi @Alpha,

I just tried this and I was able to print out the values of gt_boxes at this point. You can modify the source code and add a print statement to do this (i.e. print(gt_boxes.asnumpy())) or even better you can add a break point in the code at this point, and use your debugger to inspect the values.

If you are trying to print some var in network, make sure you disable net.hybridize(), otherwise it’s symbol not pure ndarray
