AttributeError: 'module' object has no attribute 'float32' - python-2.7

Question

I am trying to use OpenNMT-py with python 2.7. OpenNMT-py requires torchtext, so I installed it but now when I am running my program, I am getting the following error message.
Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'float32'
I tried to look for a solution to resolve this issue but couldn't find any. Any help would be appreciated.

Answer 1

This is more a guess, as you have not given information about your version. But it seems to me that your torchtext version is not compatible with your PyTorch version.
Probably when you installed torchtext you got the newer version already made for PyTorch 0.4.0. But your PyTorch version installed is still older than 0.4.0 (version 0.3.1 or so).
If that is the case you have two options. Downgrading torchtext to a version compatible to yours (probably the version before). Or upgrading PyTorch to version 0.4.0.
I hope this helps.

Answer 2

What's your pytorch version? As per the readme of the github repo of torchtext :
For PyTorch versions before 0.4.0, please use pip install torchtext==0.2.3.
I was facing this exact problem with pytorch 0.3.1 and torchtext 0.3.0. I uninstalled torchtext and then installed it with
pip install torchtext==0.2.3.
And it worked for me. Let me know if you face any other problems.
