运行我的网页抓取 python 脚本时出现错误

Question

我有一个 python 脚本，它根据从 Excel 工作簿中获取的值从网站下载图像。但是，我不断收到此错误：

信息：为 CPU 创建了 TensorFlow Lite XNNPACK 委托。 警告：尝试使用仅支持静态大小张量的委托和具有动态大小张量的图（张量#141 是动态大小张量）。

它以前从未出现过，代码只会运行并完成执行。但出现这个错误后，程序就突然结束了。

我已将我的代码粘贴在下面。 我不知道原因是什么，但它也不会从 Excel 工作簿中删除行。知道为什么吗？

主要问题是您通过

(By.CLASS_NAME, "button-2")

找到的元素不再存在。因为您检查它是否存在，所以您的大部分代码都不会运行。我已根据当前站点和您提供的信息更新了代码。

此代码将搜索 ID，打开第一个找到的产品，然后下载其图像。我没有测试任何Excel相关代码。
