报num

train=DataLoader(mydata_train,batch_size=64,shuffle=True)
上面是对数据进行打包的一个片段，但是在对数据进行批量打包时出现以下的错误

Traceback (most recent call last):
  File "D:/project/learn/aa.py", line 81, in 
    main()
  File "D:/project/learn/aa.py", line 76, in main
    train=DataLoader(mydata_train,batch_size=64,shuffle=True)#把数据打包成批量Batchsize
  File "D:ProgramDataAnacondaenvspytorchlibsite-packagestorchutilsdatadataloader.py", line 262, in __init__

    "value, but got num_samples={}".format(self.num_samples))
ValueError: num_samples should be a positive integer value, but got num_samples=0

显示这样的错误，我也不明白为啥会报这样的错误，看到一篇博客说的是将

shuffle=True改成shuffle=False

改了之后就不再报错了
