when i train and close the ann：use_character_lstm = False

[lovychen]

When I use the model to make a prediction，i also let the use_character_lstm = False，it is have some wrong， Traceback (most recent call last): File "/home/wcg/tools/local/anaconda3/lib/python3.6/site-packages/tensorflow/python/client/session.py", line 1327, in _do_call return fn(*args) File "/home/wcg/tools/local/anaconda3/lib/python3.6/site-packages/tensorflow/python/client/session.py", line 1306, in _run_fn status, run_metadata) File "/home/wcg/tools/local/anaconda3/lib/python3.6/contextlib.py", line 88, in exit next(self.gen) File "/home/wcg/tools/local/anaconda3/lib/python3.6/site-packages/tensorflow/python/framework/errors_impl.py", line 466, in raise_exception_on_not_ok_status pywrap_tensorflow.TF_GetCode(status)) tensorflow.python.framework.errors_impl.NotFoundError: Key character_lstm/bidirectional_LSTM/bidirectional_rnn/bw/coupled_input_forget_gate_lstm_cell/W_0 not found in checkpoint [[Node: save/RestoreV2_4 = RestoreV2[dtypes=[DT_FLOAT], _device="/job:localhost/replica:0/task:0/cpu:0"](_arg_save/Const_0_0, save/RestoreV2_4/tensor_names, save/RestoreV2_4/shape_and_slices)]]
