Reading Data During Training/
Why the Data Read Efficiency Is Low When a Large Number of Data Files Are Read During Training?
Why the Data Read Efficiency Is Low When a Large Number of Data Files Are Read During Training?
Updated on 2024-06-11 GMT+08:00
If a dataset contains a large number of data files (massive small files) and data is stored in OBS, files need to be repeatedly read from OBS during training. As a result, the training process is waiting for reading files, resulting in low read efficiency.
Solution
- Compress the massive small files into a package on your local PC, for example, a .zip package.
- Upload the package to OBS.
- During training, directly download this package from OBS to the /cache directory of your local PC. Perform this operation only once.
For example, you can use mox.file.copy_parallel to download the .zip package to the /cache directory, decompress the package, and then read files for training.
1 2 3 4 5 6 7 8 9 10 11 12
... tf.flags.DEFINE_string('<obs_file_path>/data.zip', '', 'dataset directory.') FLAGS = tf.flags.FLAGS import os import moxing as mox TMP_CACHE_PATH = '/cache/data' mox.file.copy_parallel('FLAGS.data_url', TMP_CACHE_PATH) zip_data_path = os.path.join(TMP_CACHE_PATH, '*.zip') unzip_data_path = os.path.join(TEMP_CACHE_PATH, 'unzip') # You can also decompress .zip Python packages. os.system('unzip '+ zip_data_path + ' -d ' + unzip_data_path) mnist = input_data.read_data_sets(unzip_data_path, one_hot=True)
