'Image is None' Problem

[jiyoungAn]

Hello, JiahuiYu.
Thank you for answering me.
However, I got this error again..
[2018-05-25 17:43:37 @data_from_fnames.py:153] image is None, sleep this thread for 0.1s. Exception in thread Thread-16: Traceback (most recent call last): File "/usr/lib/python3.5/threading.py", line 914, in _bootstrap_inner self.run() File "/usr/lib/python3.5/threading.py", line 862, in run self._target(*self._args, **self._kwargs) File "/usr/local/lib/python3.5/dist-packages/neuralgym/data/feeding_queue_runner.py", line 194, in _run data = func() File "/usr/local/lib/python3.5/dist-packages/neuralgym/data/data_from_fnames.py", line 143, in <lambda> feed_dict_op=[lambda: self.next_batch()], File "/usr/local/lib/python3.5/dist-packages/neuralgym/data/data_from_fnames.py", line 182, in next_batch img = cv2.resize(img, tuple(self.shapes[i][:-1])) cv2.error: /io/opencv/modules/imgproc/src/resize.cpp:4044: error: (-215) ssize.width > 0 && ssize.height > 0 in function resize

It seems like there is no image.
I used code in #15 for creating flist.
They are all in "data_flist" file.
At inpaint.yml, I add DATA_FLIST: city: ['data_flist/city/train_shuffled.flist','data_flist/city/validation_shuffled.flist']
and Set dataset as city.

Below is log about my Dataset

What should I do?
Thank you.

It was my mistake.
sorry I solved it! thank you

@jiyoungAn Hi~ How did you solve this problem? I have the same problem

[JiahuiYu]

@Lsiming Please check carefully of your file list locations. Issue #15 is a reference.

New to DL here...

I am also having the same problem. The log information from Dataset Info was all correct (having the correct length, etc.), and the paths in filelist is the absolute path and have been tested (e.g. cv2.imread(path) will work).

Where else could the problem be? Any help is appreciated!

@QishengLi Hi thanks for your interest first.

You can try to print inside the DataFromFNames function in our neuralgym code. I would still believe the problem is the path is incorrect. Double check the file paths especially if you are using Windows.
