+You should firstly check the version of fairseq, which should be `1.0.0a0+801a646` when you use `pip list` to show it.
+
+Note that the fairseq dependency is not officially released as `1.0.0`, so the one is not correct if you directly install it from `pip install fairseq`. Our installtion is equalivant to the following command:
+```shell
+pip install git+https://github.com/pytorch/fairseq.git@801a64683164680562c77b688d9ca77fc3e0cea7
+```
+It also requires you to have `Git` installed at first.
