Fine Tune on COCO about open-groundingdino HOT 7 CLOSED

I see two main issues:

1. "/content/Open-GroundingDino/models/GroundingDINO/ms_deform_attn.py:31: UserWarning: Failed to load custom C++ ops. Running on CPU mode Only!
   warnings.warn("Failed to load custom C++ ops. Running on CPU mode Only!")"

2. "NameError: name '_C' is not defined" which is possibly related to a cuda issue per the official grounding dino github

Hi, @nicholasprimiano

• I think this may be caused by the CUDA operator not being compiled correctly.
• Is it possible to compile the operator before executing it in colab?
• #7

from open-groundingdino.

This PR fixed this issue

#10

from open-groundingdino.

For the following problems:
1. UserWarning: Failed to load custom C++ ops. Running on CPU mode Only!
2."NameError: name '_C' is not defined"
I solved this by installing groundingdino-0.1.0 via the official code for Grounding-DINO.

I found that "ms_deform_attn.py" contains "from groundingdino import_C ", but groundingdino is not installed.

This PR fixed your issue #10 by change
"from groundingdino import_C " to "import MultiScaleDeformableAttention as _C"

from open-groundingdino.

Oops, you updated the code of "ms_deform_attn.py", I still use the previous version.
