How to use root='./data'?

E:\Python35>python work\train.py
After executing the above code, there is the following bug.
My system is windows, and My cifar data is in the file folder, E:\Python35\work\data
The error is as follows: Thank you in advance.
Traceback (most recent call last):
File “work\train.py”, line 39, in
trainset = torchvision.datasets.CIFAR10(root=‘E:\Python35\work\data’, train=True, download=False, transform=transform_train) #训练数据集
File “E:\Python35\lib\site-packages\torchvision\datasets\cifar.py”, line 62, in init
’ You can use download=True to download it’)
RuntimeError: Dataset not found or corrupted. You can use download=True to download it
Exception ignored in: <function WeakValueDictionary.init..remove at 0x0000027BF28DAF28>

TypeError: ‘NoneType’ object is not callable

You might have to use \\ or / in the path, since \ might be understood as an escape sequence.
If the error is still raised, you could try to download it again via download=True.
