I am trying to run your exercise and i am seeing this issue. Is there a known hack for this ? root@supermicro-2xvega20:~/pytorch-sentiment-analysis# python3 4\ -\ Convolutional\ Sentiment\ Analysis.py Traceback (most recent call last): File "4 - Convolutional Sentiment Analysis.py", line 30, in from torchtext import data File "/usr/local/lib/python3.6/dist-packages/torchtext/init.py", line 40, in _init_extension() File "/usr/local/lib/python3.6/dist-packages/torchtext/init.py", line 36, in _init_extension torch.ops.load_library(ext_specs.origin) File "/root/.local/lib/python3.6/site-packages/torch/_ops.py", line 105, in load_library ctypes.CDLL(path) File "/usr/lib/python3.6/ctypes/init.py", line 348, in init self._handle = _dlopen(self._name, mode) OSError: /usr/local/lib/python3.6/dist-packages/torchtext/_torchtext.so: undefined symbol: _ZN5torch3jit6MethodclESt6vectorIN3c106IValueESaIS4_EERKSt13unordered_mapISsS4_St4hashISsESt8equal_toISsESaISt4pairIKSsS4_EEE

What version of PyTorch and torchtext are you using? You need to ensure they match up, see the version compatibility table in the README of https://github.com/pytorch/text.

I believe this issue is because you need PyTorch >=1.6

[NA-Dev]

I have the latest versions that are supposed to be compatible, but still get this error. PyTorch 1.7.1 and torchtext 0.8.1.

[bentrevett]

@NA-Dev Do you still get the error with PyTorch 1.8 and torchtext 0.9? I think torchtext has had some issues with their binaries.

[adieyal]

I had the same issue - upgraded to PyTorch 1.8 and torchtext 0.9 as suggested above. This fixed the problem.
