train = datasets.MNIST("", train=True, download=True,transform = transforms.Compose([transforms.ToTensor()]))
test = datasets.MNIST("", train=False, download=True,transform = transforms.Compose([transforms.ToTensor()]))`

在 colab notebook 上执行此操作后，出现此错误：

Traceback (most recent call last)
<ipython-input-6-b81aa6cf1cbe> in <module>()
----> 1 train = datasets.MNIST("", train=True, download=True,transform = transforms.Compose([transforms.ToTensor()]))
      2 test = datasets.MNIST("", train=False, download=True,transform = transforms.Compose([transforms.ToTensor()]))

NameError: name 'transforms' is not defined*
