Training the belief tracker:**NameError: name 'self' is not defined**

[ramartya]

I am training the belief tracker. I am getting the error in the very last stage of training:

. . . Finishing 202 dialog in epoch 1 Finishing 203 dialog in epoch 1 Epoch 1, Alpha 0.002000, TRAIN entropy:95.17, Time:14.06 mins, VALID entropy:74.52 saving net to file ... Traceback (most recent call last): File "nndial.py", line 22, in model.trainNet() File "C:\Users\MY DELL\Desktop\Course\6th sem\UGP\data\NNDIAL-master\nn\NNDialogue.py", line 590, in trainNet self.saveNet() File "C:\Users\MY DELL\Desktop\Course\6th sem\UGP\data\NNDIAL-master\nn\NNDialogue.py", line 999, in saveNet 'file' :dict( [(name,eval(name)) for name in self.file_vars]), File "C:\Users\MY DELL\Desktop\Course\6th sem\UGP\data\NNDIAL-master\nn\NNDialogue.py", line 999, in 'file' :dict( [(name,eval(name)) for name in self.file_vars]), File "", line 1, in NameError: name 'self' is not defined

I am not able to understand why this error is coming

Could anyone please help with this. I would be really grateful. Thanks
