When training Mnist data set with LeNet , the following error occurs

How to solve this problem??

It’s true that the version is a bit old – the above use case needs to be modified if implemented on a newer version – from the current implementation of Iterator’s code, it no longer has the get_next method: https://gitee.com/mindspore/mindspore/blob/master/mindspore/python/mindspore/dataset/engine/iterators.py#L59

But it has __next__ method, so the above line can be modified, you can try it: > original: data = ds.get_next() > modified: data = next(ds)
