Instructions to reproduce all numbers in table 1 and table 2 of our paper:

First, download and unpack Visual Genome images: part 2 and part 2

Extract these two zip files and put the images in the same folder.

Then download VG metadata preprocessed by [37]: annotations, class info,and image metadata

Copy those three files in a single folder

Then update config.py to with a path to the aforementioned data, as well as the absolute path to this directory.

Now download the pretrained faster r-cnn checkpoint trained by [42] from https://www.dropbox.com/s/cfyqhskypu7tp0q/vg-24.tar?dl=0 and place in checkpoints/vgdet

The next step is to configure a python environment and install pytorch. To do that, first make sure CUDA 9 is installed, and then download https://download.pytorch.org/whl/cu90/torch-0.3.0.post4-cp36-cp36m-linux_x86_64.whl and pip install the downloaded whl file. Then install the rest of required packages by running pip install -r requirements.txt. This includes jupyter, as you need it to run the notebooks.

Finally, run the following to produce numbers for each table (In some cases order matters):

Table 1, Column 8, Rows 17-24: train: ipynb/train_predcls/0045.ipynb, evaluate: ipynb/eval_predcls/0011.ipynb
Table 1, Column 8, Rows 9-16: train: ipynb/train_sgcls/0051.ipynb, evaluate: ipynb/eval_sgcls/0015.ipynb
Table 1, Column 8, Rows 1-8: train: ipynb/train_predcls/0132.ipynb, evaluate: ipynb/eval_sgdet/0027.ipynb

Table 1, Column 9, Rows 17-24: train: ipynb/train_predcls/0135.ipynb, evaluate: ipynb/eval_predcls/0025.ipynb
Table 1, Column 9, Rows 9-16: train: ipynb/train_sgcls/0145.ipynb, evaluate: ipynb/eval_sgcls/0039.ipynb
Table 1, Column 9, Rows 1-8: train: ipynb/train_predcls/0135.ipynb, evaluate: ipynb/eval_sgdet/0035.ipynb

Table 2, Row 1, Columns 6-9: train: ipynb/train_predcls/0140.ipynb, evaluate: ipynb/eval_predcls/0030.ipynb
Table 2, Row 1, Columns 2-5: train: ipynb/train_predcls/0140.ipynb, evaluate: ipynb/eval_sgdet/0028.ipynb

Table 2, Row 2, Columns 6-9: train: ipynb/train_predcls/0134.ipynb, evaluate: ipynb/eval_predcls/0024.ipynb
Table 2, Row 2, Columns 2-5: train: ipynb/train_predcls/0134.ipynb, evaluate: ipynb/eval_sgdet/0034.ipynb

Table 2, Row 3, Columns 6-9: train: ipynb/train_predcls/0136.ipynb, evaluate: ipynb/eval_predcls/0026.ipynb
Table 2, Row 3, Columns 2-5: train: ipynb/train_predcls/0136.ipynb, evaluate: ipynb/eval_sgdet/0036.ipynb

Table 2, Row 4, Columns 6-9: train: ipynb/train_predcls/0132.ipynb, evaluate: ipynb/eval_predcls/0022.ipynb
Table 2, Row 4, Columns 2-5: train: ipynb/train_predcls/0132.ipynb, evaluate: ipynb/eval_sgdet/0027.ipynb

Moreover, SGCls results for table 2, which is missing from the paper due to space constraint, can be produced by:

Row 1: train: ipynb/train_predcls/0150.ipynb, evaluate: ipynb/eval_predcls/0041.ipynb
Row 2: train: ipynb/train_predcls/0144.ipynb, evaluate: ipynb/eval_predcls/0038.ipynb
Row 3: train: ipynb/train_predcls/0146.ipynb, evaluate: ipynb/eval_predcls/0040.ipynb
Row 4: train: ipynb/train_predcls/0142.ipynb, evaluate: ipynb/eval_predcls/0037.ipynb

To skip training, you may download all our pretrained checkpoints from here and place in the checkpoints/ folder. Then you only need to run notebooks in ipynb/eval_...

If GPU is not available, to skip deploying the model altogether, you may download our pre-computed model outputs from here and place in the caches/ folder. Then if you run any notebook in ipynb/eval_..., it automatically uses the cached results and does not deploy the model. Note that there is no need to run the cell that creates the model (detector = ...) as well as the next one that transfers it to cuda (detector.cuda()) and the next one that loads the checkpoint (ckpt = ...). Only run the rest of the cells.

Finally, to avoid running the code, you may just open the notebooks in ipynb/eval_... and scroll down to see the evaluation results.

Note if you get cuda-related errors, it might be due to the cuda compatibility options that were used to compile this library. In that case, you need to change the compatibility in lib/fpn/nms/src/cuda/Makefile and lib/fpn/roi_align/src/cuda/Makefile and rebuild both by running make clean and then make in both directories. Also note that pytorch 0.3.0 only has pre-built binaries for up to cuda 9. In order to run this with cuda 10 and newer GPUs, you need to build pytorch from source.
