Cannot import name plots

Part 1 (2017)

为什么我在第一次运行的时候就出错了，
import keras
import utils
from utils import plots

错误提示
ImportError Traceback (most recent call last)
in ()
1 import keras
2 import utils
----> 3 from utils import plots

ImportError: cannot import name plots

I don’t know if this will solve your problem, but maybe you need to reload utils before you can import plots?

import utils; reload(utils)
from utils import plots

#3

No, it’s still the same problem
