Cannot run train_IMDN.py

[mangoerya]

Shouldn't the Line 8 in train_IMDN.py be "import utils" instead of "from utils import utils"? And where does the function "utils.adjust_learning_rate()" used in Line 123 in train_IMDN.py first defined? Thank you.

@mangoerya Hello, I have updated the utils.py. The new utils.py contains adjust_learning_rate().

Hello, I would like to ask why there is such a mistake?Hello, Thank you. File "train_IMDN.py", line 8, in from utils import utils ImportError: cannot import name 'utils'

将from utils import utils 改为 import utils

好的，感谢您的回复，请问您这个python用的是3.5~3.7版本，还是2.7版本的呢？

你好，冒昧打扰您，我在运行train_IMDN.py时出现了这样的错误，

===> Loading datasets Traceback (most recent call last):   File "train_IMDN.py", line 74, in <module>     trainset = DIV2K.div2k(args)   File "/data1/home/chensiyu/IMDN-master/data/DIV2K.py", line 41, in init     self.images_hr, self.images_lr = self._scan()   File "/data1/home/chensiyu/IMDN-master/data/DIV2K.py", line 78, in _scan     list_hr = sorted(make_dataset(self.dir_hr))   File "/data1/home/chensiyu/IMDN-master/data/DIV2K.py", line 22, in make_dataset     assert os.path.isdir(dir), '%s is not a valid directory' % dir AssertionError: /data1/home/chensiyu/IMDN-master/training_data//DIV2K_decoded/DIV2K_HR is not a valid directory

       def _set_filesystem(self, dir_data):         self.root = dir_data + '/DIV2K_decoded'         self.dir_hr = os.path.join(self.root, 'DIV2K_HR')         self.dir_lr = os.path.join(self.root, 'DIV2K_LR_bicubic/x' + str(self.scale))

但是我将DIV2K.py文件里面的43~46行中的/DIV2K_decoded， 'DIV2K_HR' 'DIV2K_LR_bicubic/x'去掉，他就可以正常运行了，但是后面还是会出现这样的错误，还麻烦您帮我看一下，是因为什么原因。
