ValueError: some of the strides of a given numpy array are negative.

[XinCynthia]

I have successfully run train_text_embedding_flowers.sh, but when I run train_flowers.sh there is an error like following: Traceback (most recent call last): File "/home/xin/PycharmProjects/newcolorchage/train.py", line 149, in preprocess(img, desc, len_desc, txt_encoder) File "/home/xin/PycharmProjects/newcolorchage/train.py", line 68, in preprocess desc[sorted_indices, ...].transpose(0, 1), ValueError: some of the strides of a given numpy array are negative. This is currently not supported, but will be added in future releases.

could you please tell me why this happened? Thank you very much!

I got an IndexError when I tried to run train_text_embedding_flowers.sh, as the raw_desc in read_lua_file.py is NoneType. It has bothered me for a long time.

@rookie-zzw Could you elaborate your issue? e.g. stack traces.. I made this code long time ago, so detailed description would help me understand the issue.

@woozzu Thank you very much for your reply. Stack traces are as follows: Traceback (most recent call last): File "D:/code/code for Semantic Image Synthesis via Adversarial Learning/train_text_embedding.py", line 80, in std=[0.229, 0.224, 0.225]) File "D:\code\code for Semantic Image Synthesis via Adversarial Learning\data.py", line 31, in init self.data = self._load_dataset(img_root, caption_root, classes_fllename, word_embedding) File "D:\code\code for Semantic Image Synthesis via Adversarial Learning\data.py", line 46, in _load_dataset desc, len_desc = self._get_word_vectors(raw_desc, word_embedding) File "D:\code\code for Semantic Image Synthesis via Adversarial Learning\data.py", line 57, in _get_word_vectors for i in range(desc.shape[1]): IndexError: tuple index out of range

@rookie-zzw I have no problem when running it on my machine. Can you describe about your environment? e.g. python/pytorch version. And, did you accurately follow the README?

BTW, if you are interested in related projects like this, please check out our recent paper (TAGAN)

[zhouqzzw]

@woozzu I use python 3.5.2 and pytorch 0.4.1 on my machine, and I do follow the README. Surprising, I just read the paper you mentioned a few days ago! It is very meaningful and it is worth learning.

@rookie-zzw hmm.. that's strange. Can you confirm that raw_desc in this line is None? If so, I think the dataset might be the problem. Please double check the paths in CONFIG, or re-download the dataset.

@woozzu I tried the solution you suggested, but every time I step through that line, I get the following error: Unable to display children: Error resolving variables Trackback(most recent call last): File "C:\Program Files\JetBrains\PyCharm 2017.3\helpers\pydev_pydevd_bundle\pydevd_comm.py", line 1029, in do_it _typeName, val_dict = pydevd_vars.resolve_compound_variable(self.thread_i, self.frame_id, self.scope, self.attributes) TypeError: 'NoneType' object is not iterable

@rookie-zzw I'm sorry but I can't reproduce your error. If you can use pdb or something for debugging, printing any suspicious variables might be helpful to find the culprit.

I had the same error and and was able to fix it by copying the numpy array (the indices are thus turned positive) :

packed_desc = nn.utils.rnn.pack_padded_sequence(
        desc[sorted_indices.copy(), ...].transpose(0, 1),
        len_desc[sorted_indices]
