我正在尝试在 TVM 中运行第一个示例，但在一开始我就遇到了这些错误。我已经使用LLVM ON和OpenCL On构建了 tvm(安装了用于 opencl 应用程序的英特尔 sdk - opencl 2.1(。构建过程顺利进行，所以我想一切都到位了。
但是，当我尝试从此示例中运行此代码片段时，我收到这些错误： 编译深度学习模型的快速入门教程：

我还尝试发送图形模型以查看这是否是原因，但无济于事！我仍然收到相同的错误消息，这次使用我提供的模型，即：

我什至尝试更改op_level，这不会影响任何事情。我应该怎么做才能摆脱这个问题？
您看到的不是错误，而是警告。由于 TVM 找不到包含优化计划的日志文件，因此它将仅使用默认(回退(计划。
要消除警告，您需要使用 AutoTVM(如本例所示(来查找优化的计划。之后，您可以继续编译。
