BiLSTM-CRF code not working

[mnishant2]

Hi I completed the build_data, but when running train.py the ner_learner throws following error
Traceback (most recent call last): File "/data/storage_hpc_nishant/ade_bench/bilstm_crf/train.py", line 185, in <module> main() File "/data/storage_hpc_nishant/ade_bench/bilstm_crf/train.py", line 181, in main learn.fit(train, dev) File "/data/storage_hpc_nishant/ade_bench/bilstm_crf/model/ner_learner.py", line 186, in fit self.train(epoch, nbatches_train, train_generator, fine_tune=fine_tune) File "/data/storage_hpc_nishant/ade_bench/bilstm_crf/model/ner_learner.py", line 217, in train for batch_idx, (inputs, targets, sequence_lengths) in enumerate(train_generator): File "/data/storage_hpc_nishant/ade_bench/bilstm_crf/model/ner_learner.py", line 139, in data_generator "word_ids": np.asarray(word_ids) ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (5,) + inhomogeneous part.
Any pointers to what could be the reason
