[zcx9112040]

At first i put 1000 photos in data/train ,then i run "python train_nn.py --cnf configs/c_128_5x5_32.py",there is nothing wrong, but when i put 35000 photos in data/train, i got error, I sure i have changed the labels too,failed as this: Traceback (most recent call last): File "train_nn.py", line 41, in main() File "/usr/local/lib/python2.7/dist-packages/click/core.py", line 716, in call return self.main(*args, **kwargs) File "/usr/local/lib/python2.7/dist-packages/click/core.py", line 696, in main rv = self.invoke(ctx) File "/usr/local/lib/python2.7/dist-packages/click/core.py", line 889, in invoke return ctx.invoke(self.callback, **ctx.params) File "/usr/local/lib/python2.7/dist-packages/click/core.py", line 534, in invoke return callback(*args, **kwargs) File "train_nn.py", line 38, in main net.fit(files, labels) File "/usr/local/lib/python2.7/dist-packages/nolearn-0.6a0.dev0-py2.7.egg/nolearn/lasagne/base.py", line 416, in fit self.train_loop(X, y) File "/home/zcx/kaggle_diabetic-deterministic/nn.py", line 219, in train_loop X, y, self.eval_size) File "/home/zcx/kaggle_diabetic-deterministic/nn.py", line 126, in train_test_split X, y, test_size=eval_size) File "/home/zcx/kaggle_diabetic-deterministic/data.py", line 293, in split train, test = split_indices(files, labels, test_size, random_state) File "/home/zcx/kaggle_diabetic-deterministic/data.py", line 281, in split_indices labels = get_labels(names, per_patient=True) File "/home/zcx/kaggle_diabetic-deterministic/data.py", line 222, in get_labels return np.vstack([labels[left], labels[~left]]).T File "/usr/local/lib/python2.7/dist-packages/numpy/core/shape_base.py", line 228, in vstack return _nx.concatenate([atleast_2d(_m) for _m in tup], 0) ValueError: all the input array dimensions except for the concatenation axis must match exactly what should i do? can you give me some advice?
