Pytorch is a very useful machine learning framework for building applications. Using it you can build apps based on computer vision and natural language processing. If you are getting the error modulenotfounderror: no module named torchtext.legacy then this post is for you.
In this entire tutorial, you will know why this is no module named torchtext.legacy error comes and how to solve it.
What is Modulenotfounderror?
