why TypeError？

[yindahu87]

Why am I running Word. py,the following error occurred：
Traceback (most recent call last):
File "C:\GithubProjects\Diffusion-BERT-main\word_freq.py", line 18, in
for iid in data['input_ids']:
TypeError: string indices must be integers

I suspect that train_data should be a datasets.Dataset object but somehow it is a dict now. Did you modify the code around there?

[yindahu87]

我怀疑那应该是一个数据集。数据集对象，但不知何故它现在是一个字典。你修改了那里的代码吗？train_data

不小心对train_data做了点改动 您是对的 谢谢您
