code for generating data set ES-ImageNet with corresponding training code

dataset generator

some codes of ODG algorithm
The variables to be modified include datapath (data storage path after transformation, which needs to be created before transformation) and root_Path (root directory of training set before transformation)

file name	function
traconvert.py	converting training set of ISLVRC 2012 into event stream using ODG
trainlabel_dir.txt	It stores the corresponding relationship between the class name and label of the original Imagenet file
trainlabel.txt	It is generated during transformation and stores the label of training set
valconvert.py	Transformation code for test set.
valorigin.txt	Original test label of ImageNet-1K. Put it in the same folder with valconvert.py if you need.
vallabel.txt	It is generated during transformation and stores the label of training set.

dataset usage

codes are in ./datasets
some traing examples are provided for ES-imagenet in ./example An example code for easily using this dataset based on Pytorch

from __future__ import print_function
import sys
sys.path.append("..")
from datasets.es_imagenet_new import ESImagenet_Dataset
import torch.nn as nn
import torch

data_path = None #TODO:modify 
train_dataset = ESImagenet_Dataset(mode='train',data_set_path=data_path)
test_dataset = ESImagenet_Dataset(mode='test',data_set_path=data_path)

train_sampler = torch.utils.data.distributed.DistributedSampler(train_dataset)
test_sampler  = torch.utils.data.distributed.DistributedSampler(test_dataset)
train_loader = torch.utils.data.DataLoader(train_dataset, batch_size=batch_size, shuffle=False, num_workers=1,pin_memory=True,drop_last=True,sampler=train_sampler)
test_loader = torch.utils.data.DataLoader(test_dataset, batch_size=batch_size, shuffle=False, num_workers=1,pin_memory=True)

for batch_idx, (inputs, targets) in enumerate(train_loader)
  pass
  # input = [batchsize,time,channel,width,height]
  
for batch_idx, (inputs, targets) in enumerate(test_loader):
  pass
  # input = [batchsize,time,channel,width,height]

Note: model (a), (b) and (c) are stored in ./pretrained_model Some problems related to model loading can be referred to the issue. If you want to test 2D-CNN with reconstructed gray set, you can use this notebook

Download

The datasets ES-ImageNet (100GB) for this study can be download in the Tsinghua Cloud1 or Openl
The converted event-frame version (40GB, events are organized as 8 event-frames instead of lists) can be found in Tsinghua Cloud2, IT MAY BE BUGGY, STILL NEED TO BE CHECKED
If you only need the validation set, you can download it in Tsinghua Cloud3 separately
