demo.py error!

[lfdeep]

Hello, Excuse me, your demo.py can only test videos, can't test pictures？

hi, i have build target pycaffe successfully.But when i run the demo,no module named cmp_trie.
Do you have this problem?

[MichalBusta]

installation step 3 ?

installation step 3 ?

Hi MichalBusta,

I add some layers in both model_cz.prototxt and tiny.prototxt, when I train the model by python train.py, one error occur: valueError: cannot reshape array of size 6204 into shape(22,1,141).This error happens in 260th line in validation.py, that is ctc_f = ctc_f.reshape(ctc_f.shape[0], ctc_f.shape[1], ctc_f.shape[3]). As we know, 6204=2221141, so I want to know than can I change ctc_f = ctc_f.reshape(ctc_f.shape[0], ctc_f.shape[1], ctc_f.shape[3]) to ctc_f = ctc_f.reshape(ctc_f.shape[0], 2ctc_f.shape[1], ctc_f.shape[3]) so that the result is (22,2,141)?
Can you help me? Thank you very much.

I had the same problem. Did you solve the problem ?

How if I want to run demo.py in python3 ?
