问题是这个switch_to.frame('trustarcNoticeFrame')没有切换到iframe，iframe有cookie管理器对话框，下面是适合我的代码片段。

btnYes = "//div[@class='pdynamicbutton']/a[@class='call']"
iframe = "//iframe[@title='TrustArc Cookie Consent Manager']"

ifr = driver.find_element(By.XPATH, iframe)
driver.switch_to.frame(ifr)

eleYes= driver.find_element(By.XPATH, btnYes)
eleYes.click()

使用WebDriverWait并等待帧可用，然后切换。

WebDriverWait(driver,10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe.truste_popframe")))
WebDriverWait(driver,10).until(EC.element_to_be_clickable((By.XPATH,"//a[text()='Accept all']"))).click()

您需要等待以下库。

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