尝试将 Tensorflow Lite Micro 集成到我的 ESP32 Arduino 项目时，在 Tensorflow Lite Micro 框架中编译错误

Question

嗨，Whosebug 社区，

我正在尝试使用 PlatformIO 和 Arduino 框架（不是 ESP-IDF）在我的 ESP32 上运行获得一个利用 Tensorflow Lite Micro 的项目。基本上，我遵循了这个媒介 post https://towardsdatascience.com/tensorflow-meet-the-esp32-3ac36d7f32c7 中的指南，然后将所有内容都包含在我现有的 ESP32 项目中。

我的项目在集成 Tensorflow Lite Micro 之前编译正常，但自从集成它后，我收到以下似乎与 Tensorflow 框架本身有关的编译错误。当我取消注释与 Tensorflow 相关的所有内容时，它编译正常。但是就在只包含以下头文件时，它会中断：

#include "tensorflow/lite/micro/kernels/micro_ops.h"
#include "tensorflow/lite/micro/micro_error_reporter.h"
#include "tensorflow/lite/micro/micro_interpreter.h"
#include "tensorflow/lite/micro/micro_mutable_op_resolver.h"
#include "tensorflow/lite/schema/schema_generated.h"
#include "tensorflow/lite/version.h"

有人知道这些错误是从哪里来的吗？我能做些什么来解决这些错误？

这是错误跟踪：

Answer 1

我暂时解决了这个问题，方法是从 Arduino 框架切换到 ESP-IDF 框架。有了这个，它就像一个魅力。

Answer 2

今天我遇到了类似的问题。我使用 TensorFlowLite_ESP32 库而不是 Arduino_TensorFlowLite 解决了这个问题。您需要下载此库并添加 #include 行。希望对你也有帮助
