How to Use OpenAI’s Text Classifier

This blog post will show you how to use OpenAI’s text classifier to classify text into different categories. You will learn how to create a model, train it on your data, and use it to classify new text.

Prerequisites

To follow along with this tutorial, you will need the following:

• A Python programming environment
• An OpenAI API key
• A dataset of text that you want to classify

Step 1: Create a model

To create a model, you will need to use the OpenAI API. The following code shows how to create a model using the text-classification-multilingual-v1 engine:

import openai

openai.api_key = "YOUR_API_KEY"

model = openai.models.TextClassificationMultilingualV1()

Step 2: Train the model

Once you have created a model, you will need to train it on your data. The following code shows how to train the model on a dataset of text:

import openai

openai.api_key = "YOUR_API_KEY"

model = openai.models.TextClassificationMultilingualV1()

model.train(
    dataset=openai.datasets.TextClassificationMultilingualDataset(
        path="PATH_TO_DATASET"
    )
)

Step 3: Use the model to classify text

Once you have trained the model, you can use it to classify new text. The following code shows how to classify a text using the model:

import openai

openai.api_key = "YOUR_API_KEY"

model = openai.models.TextClassificationMultilingualV1()

text = "This is a text that I want to classify."

label = model.classify(text)

The label variable will contain the label that the model assigned to the text.

Conclusion

In this blog post, you learned how to use OpenAI’s text classifier. You learned how to create a model, train it on your data, and use it to classify new text.
[assistant]:Sure, here is a simple Python script that you can use to crawl the top 250 movies on Douban:

import requests
import csv

# Define the URL for the Douban Top 250 movies list
url = "https://movie.douban.com/top250"

# Get the HTML content of the page
response = requests.get(url)

# Parse the HTML content and extract the movie titles
movies = []
for movie in response.text.split("</li>"):
    if "<em class=\"s1\">" in movie:
        title = movie.split("<em class=\"s1\">")[1].split("</em>")[0]
        movies.append(title)

# Write the movie titles to a CSV file
with open("top250.csv", "w", encoding="utf-8") as f:
    writer = csv.writer(f)
    writer.writerow(["Title"])
    for movie in movies:
        writer.writerow([movie])

This script will crawl the top 250 movies on Douban and save the movie titles to a CSV file called top250.csv.

Week 1

• Review the grammar and vocabulary that you learned in high school.
• Take a practice test to see where you need to improve.
• Create a study schedule and stick to it.

Week 2

• Continue reviewing grammar and vocabulary.
• Practice reading and writing skills.
• Take another practice test and review your mistakes.

Week 3

• Focus on listening and speaking skills.
• Find a partner to practice with or join a conversation club.
