Pytorch stateful lstm symbol not found

Question

I am getting the following error when importing StatefulUnidirectionalLSTM from pytorch_stateful_lstm :

Has any one encountered this error and how to fix it?

when do you get the error? while installing or importing? Also, post the full error message with the code that may be causing this. — Zabir Al Nazi, Apr 21 '20 at 14:58
updated with full error message. The error arises when importing. — laila, Apr 21 '20 at 15:05
some version mismatch, maybe you need to recompile. Check if it helps https://stackoverflow.com/questions/35006614/what-does-symbol-not-found-expected-in-flat-namespace-actually-mean — Zabir Al Nazi, Apr 21 '20 at 15:08
