Dense Captioning Evaluation on VG Dataset

[Wykay]

Hello,

I am currently tring to reproduce the result of task dense captioning of GRiT. I have trained the model by default setting and got the checkpoint of it. Then I ran inference on VG test set and got the json result by

python train_net.py --num-gpus-per-machine 8 --config-file configs/GRiT_B_DenseCap.yaml --output-dir-name ./output/grit_b_densecap --eval-only MODEL.WEIGHTS models/grit_b_densecap.pth

However, when installing the environment of DenseCap, I was stuck in the installation of torch on my GPU machine which has a CUDA version of 12.0. I always met this error:

Make Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_cublas_device_LIBRARY (ADVANCED)
linked by target "THC" in directory /root/torch/extra/cutorch/lib/THC

Could you tell me what platform you use to install DenseCap and perform evaluation?

Thanks a lot!

To evaluate the result, you can use the docker as provided in jcjohnson/densecap#95

Hi, Jialian.

I have built the environment for densecap using the docker image as provided. Could you please tell me more specifically how you use the output/grit_b_densecap/vg_instances_results.json or checkpoint file to evaluate on it so as to get the mAP result?

Found an evaluator of VG in python

In their Lua evaluation code, there is a place that obtains model inference results. We replace it with our result read from json.

Hi, Jialian!

Have you ever met this problem : "attempt to concatenate a nil value" in eval_utils.lua ?

I met this when evaluating the model on image 63.jpg while reading ground truth

It seems likes that it is a problem caused by nn.LanguageModel.idx_to_token when the idx=10579, the token is "nil", which will cause error when being concatenated.

I only changed the code to read the results json file, and no other changes. I didn't have errors in the evaluation code.

Could you please provide me the evaluation code you edit so i could replace it in my docker? Thanks

Can you show more details on how you hit the issue? For example, share the full error stack.

I found the error: I didn't replace the vocab_size and idx_to_token in LM model, thank you all so much.

@Evenyyy 您好，请问一下您可以提供一下您编辑的用vg_instances_results.json文件在DenseCap评估的代码嘛，非常感谢您！两位大佬上面的聊天我还是没看太懂
