NoneType' object is not subscriptable #2

Closed Aliweka2020 closed 2 years ago

Aliweka2020 commented 2 years ago

when running your code on kaggle server this error appears to me

File "/kaggle/input/iter302/Iter-Deformable-DETR-main/detr/deformable_transformer.py", line 395, in forward pred_boxes = self.bbox_embedlid + inverse_sigmoid(reference_points) TypeError: 'NoneType' object is not subscriptable

In your code, you initialize bbox_embed as: self.bbox_embed = None self.class_embed = None

then in the forward pass to try to subscripe it.

when running your code on my own laptop with RTX2060 GPU, this error appears

assert (input_spatial_shapes[:, 0] * input_spatial_shapes[:, 1]).sum() == Len_in

RuntimeError: CUDA error: an illegal memory access was encountered CUDA kernel errors might be asynchronously reported at some other API call,so the stacktrace below might be incorrect. For debugging consider passing CUDA_LAUNCH_BLOCKING=1.

it doesn't work for me

bbox_embed and class_embed are initialized here: https://github.com/zyayoung/Iter-Deformable-DETR/blob/0a1f881c8b2b119fc4248f97df9ec80e0921d685/detr/deformable_detr.py#L98-L99

For the illegal memory access issue, you may follow the instruction "for debugging consider passing CUDA_LAUNCH_BLOCKING=1." You are welcome to post the output if it still doesn't work for you.
