这个错误消息表明在使用webdriver对象时调用了find_element_by_xpath方法，但是该对象并没有这个方法。可能是因为没有正确导入webdriver库或者使用了错误的webdriver对象。

AttributeError: WebDriver object has no attribute find_element_by_xpath

这个错误通常发生在使用Selenium时，代码中没有正确导入WebDriver或者WebDriver对象名字不正确导致无法调用find_element_by_xpath方法。

你可以检查代码中的以下几点：

1. 是否正确导入了selenium库；
2. 是否正确创建了WebDriver对象；
3. 是否将WebDriver对象的名字写错了；
4. 是否使用了正确的方法名。

如果以上几点都没有问题，你可以尝试更新selenium库或者重新安装selenium库。另外，你也可以试着使用其他定位元素的方法，例如find_element_by_id、find_element_by_name等方法。

webdriver object has no attribute find_element_by_css_selector

This error message usually indicates that you are trying to use the `find_element_by_css_selector` method on the wrong object.

Most likely, you are trying to use `find_element_by_css_selector` on a `webdriver` object, which does not have this method. Instead, you should use it on a `WebElement` object.

For example, if you want to find an element by its CSS selector, you can first use the `find_element` method to locate the element, and then use the `find_element_by_css_selector` method on the resulting `WebElement` object:

# Find the parent element
parent_element = driver.find_element(By.XPATH, '//div[@class="parent"]')

# Find the child element by CSS selector
child_element = parent_element.find_element_by_css_selector('.child')

Alternatively, you can use the `find_elements_by_css_selector` method on a `webdriver` object to find multiple elements that match the CSS selector:

# Find all elements with class "my-class"
elements = driver.find_elements_by_css_selector('.my-class')
