warpctc error: AttributeError: 'module' object has no attribute 'WarpCTC'

[qieaaa]

hello , I tried to run you code about LSTM-CTC, but warpctc doesnt work well .I wonder if you met this problem when run the mxnet with warpctc,I'm looking forward for you help.Here is what I did:

1. I installed mxnet , warp-ctc respectively, totally follow the official guide. Then I run tests. each of them works well.

2. I enabled warpctc in mxnet ,commented out following lines in mxnet/config.mk
   WARPCTC_PATH = $(HOME)/warp-ctc
   MXNET_PLUGINS += plugin/warpctc/warpctc.mk
   rebuilt mxnet after that.

3. then I get the following results,last line shows:
   make[1]: Leaving directory `/home/lab/mxnet/dmlc-core'
   then the make process stopped. I found mxnet still works,but there are no bin and lib files in mxnet. when I run the lstm_ocr demo,it shows:
   Traceback (most recent call last):
   File "lstm_ocr.py", line 157, in
   symbol = sym_gen(SEQ_LENGTH)
   File "lstm_ocr.py", line 148, in sym_gen
   num_label = num_label)
   File "/home/lab/mxnet/example/warpctc/lstm.py", line 77, in lstm_unroll
   sm = mx.sym.WarpCTC(data=pred, label=label, label_length = num_label, input_length = seq_len)
   AttributeError: 'module' object has no attribute 'WarpCTC'

Have you solved this problem? I met the same problem with you.
