在Selenium Python中web抓取元素时超时异常

Question

我在尝试单击下拉链接时遇到超时异常-我已经尝试了在各种论坛上找到的所有解决方案（例如：将等待时间增加到60秒，使用time.sleep，更改定位器） 但这个错误似乎并没有消失

FWIW：我试图点击的页面和链接在1秒钟内加载，所以不确定发生了什么

有人能帮我做点什么吗

代码片段如下所示：

def __init__(self, driver):  # initialize each WebElement here
    self.driver = driver
    wait = WebDriverWait(self.driver.instance, 10)
    self.data_dropdown = wait.until(
        EC.visibility_of_element_located((
            By.XPATH, '//*[@id="ProjectDataTab"]')))  # Data dropdown
    self.view_all_link = wait.until(
        EC.visibility_of_element_located((
            By.LINK_TEXT, 'View All')))  # View All link
