I am a first time user trying to use PyTorch 0.4.0 (installed using anaconda in my custom environment that uses python 3.6 among other things) to generate text. I am running the code found in the GitHub location pytorch/examples/word_language_model by training it on a really small data set (the children’s book Telegraph Boy). I am running it locally on my Mac which does not have an NVIDIA GPU. The command I use is:


python main.py --data <location of data containing test, valid and train files> --epochs 10 --tied


This works fine. When trying to generate new text however (using >> python generate.py), I get an error as below…what is wrong?
