    lstm problem

    There's  a line in     lstm.py  .    
    

    last_states.append(LSTMState(c=mx.sym.Variable("l%d_init_c" % i), h=mx.sym.Variable("l%d_init_h" % i)))

    I found Variable c & h are not initialized or setted. So why the symbol is right?

  • Unable to train insightocr on VGG_Text data

    Unable to train insightocr on VGG_Text data

    Hi, I am not able to train insightocr using train_crnn.py file. I have downloaded the Synthetic Word Dataset(10GB) from VGG_Text. Then i have made following changes-

    • In config.py, default.dataset = 'vgg' dataset.vgg.dataset_path = 'path of vgg dataset'

    • In train_crnn.py, In line 70- image_set='annotation_train' In line 71- image_set='annotation_val'

    annotation_train file contains data in following format-

    ./2425/1/115_Lube_45484.jpg 45484 image_name index

    These index are mapped to label in lexicon.txt file. But in the entire script, we have not passed the path of lexicon.txt file. So how the model is going to train.

    Kindly provide some solution to train it on VGG_text dataset.

    Also what is config.image_path in config.py?
