Python selenium.common.Exception.TimeoutException-谷歌图像抓取

Python selenium.common.Exception.TimeoutException-谷歌图像抓取,python,selenium,web-scraping,Python,Selenium,Web Scraping,我正在使用这段代码从谷歌图像搜索结果中抓取一些图像。但是,有一个try exception块,其中我的代码给出了此错误: selenium.common.Exception.TimeoutException D:\Downloads\google\u images\u downloader-master\google\u images\u downloader-master>[19680:952:0326/213123.951:错误:ssl\u客户端\u套接字\u impl.cc(941)]握手

我正在使用这段代码从谷歌图像搜索结果中抓取一些图像。但是,有一个
try exception
块,其中我的代码给出了此错误:

selenium.common.Exception.TimeoutException

D:\Downloads\google\u images\u downloader-master\google\u images\u downloader-master>[19680:952:0326/213123.951:错误:ssl\u客户端\u套接字\u impl.cc(941)]握手失败;返回-1,SSL错误代码1,网络错误-100

以下是代码块:

number_of_scrolls = int((num_requested / 400) + 10)
for _ in range(number_of_scrolls):
   for __ in range(10):
      driver.execute_script("window.scrollBy(0, 1000000)")
      time.sleep(0.2)
   time.sleep(0.5)
   try: 
      wait = WebDriverWait(driver, 10)
      element = wait.until(EC.element_to_be_clickable((By.XPATH, "//input[@value='Show more results']")))
      element.click()  
   except Exception as e:   
       print ("Less images found:", e)
       break   

另外,我正在使用Chrome作为我的网络驱动程序,你确定你面临这个问题吗?因为我从你提供的链接复制了相同的代码,它对我来说工作正常。只有我做了一些改变

  • 我用的不是firefox,而是chrome
  • 无法在
    https://www.google.com/search?q=Poecile%20montanus%20bird&source=lnms&tbm=isch
    。获取语法错误:驱动程序的非ASCII字符“\xc4”。通过xpath(“//input[@value='Więcej wyników'])查找元素。单击()due ASCII字符。为避免此错误,我已将xpath更改为
    驱动程序。通过\u xpath(“//input[@value='W']”)查找\u元素。单击()
    ,因此我们得到
    ('Less images found:',NoSuchElementException())
    。请查看屏幕截图以了解更多详细信息

    您无法通过以下方式捕获TimeoutException:

    except Exception as e:
    
    你应使用:

    except TimeoutException:
    
    您还必须从Selenium导入该异常:

    from selenium.common.exceptions import TimeoutException
    

    对我来说,我必须用xpath(//input[@value='Show more results'])为英语提供
    find_element\u。此外,在屏幕截图中,我看到下载的总图像显示所有案例的0/0错误
    消息:元素不可交互
    ,这就是为什么它会得到0/0图像,就像在屏幕截图中一样,在输出中,你会得到0图像,因为你在代码中使用的定位器有0个匹配元素。你需要确保你通过了正确的定位器。git上的程序有旧的定位器,现在无效。知道如何让ro用户获得更新的outr校正定位器吗?对Selenium没有太多经验不确定,但我认为可能值得向git所有者核实到底发生了什么变化
