我正在按照 Github 上的 CNTK 教程使用 CTF 阅读器功能。
def create_reader(path, is_training, input_dim, label_dim):
return MinibatchSource(CTFDeserializer(path, StreamDefs(
features = StreamDef(field='x', shape=input_dim, is_sparse=True),
labels = StreamDef(field='y', shape=label_dim, is_sparse=False)
)), randomize=is_training, epoch_size= INFINITELY_REPEAT if is_training else FULL_DATA_SWEEP)
除非输入文件大小大于某个大小(未知),否则这完全可以正常工作。然后它会抛出这样的错误:
WARNING: Sparse index value (269) at offset 8923303 in the input file (C:\local\CNTK-2-0-beta6-0-Windows-64bit-CPU-Only\cntk\Examples\common\data_pos_train_balanced_ctf.txt) exceeds the maximum expected value (268).

我发现在文件 TextParser.cpp https://github.com/Microsoft/CNTK/blob/5633e79febe1dc5147149af9190ad1944742328a/Source/Readers/CNTKTextFormatReader/TextParser.cpp中引发了这种错误
对此有什么解决方案或解决方法?
