get_view include aloscene objects

[Johansmm]

In an inference procedure, when we try to use get_view method to show the inference, the inference is ignored if we push it directly inside the method, drawing the GT objects and thus generates 'false views'. The following code try to explain better the idea:

import alonet

detr = alonet.detr.LitDetr(weights = "detr-r50")
data_loader = alonet.detr.CocoDetection2Detr(sample = True, batch_size = 1)

frame = next(iter(data_loader.val_dataloader()))
frame = frame[0].batch_list(frame)

pred_boxes = detr.inference(detr(frame))
pred_boxes[0].labels[:] = 1000 # Change ID to explain better the problem

# Ignore predictions and draw GT
frame.get_view([pred_boxes[0]]).render()

# Correct view
frame.get_view([pred_boxes[0].get_view(frame[0])]).render()

Some of this things to do:

• Launch an error to show the misunderstanding of the use of aloscene.
• Update get_view to enable this feature.
