Sentiment Analysis on Amazon Reviews

This runs on Python 3.6.8.

This project requires fast.ai version 0.7.

• Use the configuration file to set up the environment. I used conda to manage the packages and environment.
• Note that the code below is for cpu, but I have included the environment file for gpu enviroment.yml.

conda env create -f environment-cpu.yml
conda activate fastai-cpu

Or for updating the environment:

conda env update -f environment-cpu.yml

• Download the file named "amazon_review_full_csv.tar.gz "

Note that you will have to download the pre-trained language model. I have used the wikitext103 language created by Stephen Merity @ Salesforce research. Here is a link from fast.ai, and here is a command for the terminal:

$ wget -nH -r -np -P {PATH} http://files.fast.ai/models/wt103/
