Python 无法抓取动态加载的文本文件

我想收集美国农业部的数据，特别是https://mymarketnews.ams.usda.gov/viewReport/2960，我收集了2020年9月14日至7月的所有最新数据.他们似乎改变了存储数据的方式，所以从2020年7月到2017年10月，他们以文本文件的形式存储，我想挖掘这些文件，但我找不到可靠的方法来做到这一点.

我已经try 了多种方法，到目前为止，我的selenium导入出现了问题，无法使用ChromeDriver，这可能会解决我的问题

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

URL = 'https://mymarketnews.ams.usda.gov/viewReport/2960'

def extract_text_file_links(driver):
    # Modify the selector as necessary
    elements = driver.find_elements(By.CSS_SELECTOR, 'a[href$=".txt"]')
    return [element.get_attribute('href') for element in elements]

def main():
    # Set up the webdriver
    options = webdriver.ChromeOptions()
    options.headless = True  # This runs Chrome in the background
    driver = webdriver.Chrome(executable_path='changed path', options=options)

    try:
        driver.get(URL)
    
        # Waiting for a specific element to ensure the page has loaded.
        # Adjust the selector and timeout as necessary.
        WebDriverWait(driver, 30).until(EC.presence_of_element_located((By.CSS_SELECTOR, 'a[href$=".txt"]')))
    
        text_file_links = extract_text_file_links(driver)
        for link in text_file_links:
            print(link)
        # You can then download these files as demonstrated in previous answers.

    finally:
        driver.quit()

if __name__ == "__main__":
    main()

ValueError: Timeout value connect was <object object at 0x0000020075CC4820>, but it must be an int, float or None.

不管怎样，我都不能让这个刮刀工作，文件都在网站上的一个文件夹里，我不知道如何正确地刮掉这样的东西
