*** TypeError: object of type 'numpy.int64' has no len()

	all_risk_scores = np.zeros((len(loader)))
	all_censorships = np.zeros((len(loader)))
	all_event_times = np.zeros((len(loader)))

In pdb,'loader' is the type of 'torch.utils.data.dataloader.DataLoader',but when I use iter to check the content of the 'loader',another error occures: *** TypeError: 'numpy.int64' object is not iterable.How could I solve the problem?Thanks a lot.

在pdb中，'loader'是'torch.utils.data.dataloader. DataLoader'的类型，但是当我使用iter检查'loader'的内容时，另一个错误发生了：* 类型错误：'numpy.int64'对象不可迭代。我如何解决这个问题？谢谢你，我很好

I solve the problem by:

all_risk_scores = np.zeros((len(loader.dataset)))
all_censorships = np.zeros((len(loader.dataset)))
all_event_times = np.zeros((len(loader.dataset)))
