Hi Jinkai,

When I try to use the SMPLGait to apply on other dataset, during the training process, the smplgait.py throws the error that: smpls = ipts[1][0] # [n, s, d] IndexError: list index out of range It is also interesting that I used 4 GPUs in the training. 3 of them could detect the the ipts[1][0] tensor with size 1. However, the fourth one failed to do so. Could I know how I can solve this?

Hi. Im jjun. I read your paper impressively.

We don't currently live in China, so it is difficult to use dataset on baidu disk.

If you don't mind, is there a way to download the dataset to another disk (e.g Google drive)?

Your work promotes the application of gait recognition in real scenes, can you provide the topology diagram of the SMPL 3D skeleton in Gait3D? Because the specific meaning of the 24 joint points is not stated in your data description document.

When I try to use the ROMP to generate out the 3D mesh, I detect there is a version conflict with the ROMP used by SMPLGait. Could I know which version of the ROMP the SMPLGait used? In this way I could use the SMPLGait to run on other ReID dataset.

Hi! The total iteration in your code is set to 180000, and you report the total epoch as 1200 in your paper. What's the relationship between iteration and epoch?

Hi! I 'd like to know some details about data generation in NPZ files.

In npz file: 1 What's the order of "pose"? SMPL pose parameter should be [24,3] dim, how did you convert it to [72,]? The order is [keypoint1_angel1, keypoint1_angle2, keypoint1_angle3, keypoint2_angel1, keypoint2_angle2, keypoint2_angle3...] or [keypoint1_angle1, keypoint2_angle1... keypoint1_angle2, keypoint2_angle2... keypoint1_angle3, keypoint1_angle3... ] ?

2 How did you generate pose into SMPL format,SPIN format , and OpenPose format? What's the order of the second dim? Is the keypoint order the same with SMPL model?

3 In pkl file: For example, dim of data in './0000/camid0_videoid2/seq0/seq0.pkl' is [48,85]. What's the order of dim 1? Is it ordered by time order or shuffled?

I'm trying to run GREW pretreatment code but it generates no GREW-pkl folder at the end of the process. I debugged myself and checked if the --dataset flag is set properly and the to_pickle list size before saving the pickle file. The flag is well set but the size of the list is always 0.

I downloaded the GREW dataset from the link you guys sent me and made de GREW-rearranged folder using the code provided. I'll keep investigating what is causing such an error and if I find I'll set a fixing PR.

Can you make a detailed description of the pose data? This is the path of one frame pose and the corresponding content of the txt file Gait3D/2D_Poses/0000/camid9_videoid2/seq0/human_crop_f17279.txt '311,438,89.201164,62.87694,0.57074964,89.201164,54.322254,0.47146344,84.92382,62.87694,0.63443935,42.150383....' I have 3 questions. Q1: what does 'f17279' means? Q2: what does the first number (e.g. 311) in the txt file mean? Q3: which number('f17279' or '311') should I regard as a base when I order the sequence? Thank you very much!
