why is there a problem "AttributeError: 'BatchGenerator' object has no attribute 'next'? about brats2019

[JohnleeHIT]

As a hint told: "BatchGenerator' object has no attribute 'next'" BatchGenerator is a iterator, we can get the data by calling next(BatchGenerator ) but not BatchGenerator.next()

这两种都试了，都是报这个错误。我严重怀疑是不是tensorflow版本问题，我用的1.12

I have solved this problem!
adding the next method in class BatchGenerator(Iterator):
def next(self):
"""For python 2.x.
# Returns
The next batch.
"""
with self.lock:
index_array = next(self.index_generator)
# The transformation of images is not under thread lock
# so it can be done in parallel
return self._get_batches_of_transformed_samples(index_array)
