在尝试将Tensorflow Lite Micro集成到我的ESP32 Arduino项目时，在Tensorflow L

Question

Hi-stackkoverflow社区，

我正试图让一个利用Tensorflow Lite Micro的项目在我的ESP32上运行，使用PlatformIO和Arduino框架(而不是ESP-IDF(。基本上，我遵循了这篇媒体文章中的指南https://towardsdatascience.com/tensorflow-meet-the-esp32-3ac36d7f32c7然后将所有内容都包含在我现有的ESP32项目中。

在集成Tensorflow Lite Micro之前，我的项目编译得很好，但自从集成之后，我遇到了以下编译错误，这些错误似乎与Tensorflow框架本身有关。当我取消注释与Tensorflow相关的所有内容时，它编译得很好。但当只包括以下头文件时，它就崩溃了：

#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"

有人知道这些错误来自哪里吗？我能做些什么来解决这些错误？

以下是错误跟踪：

Answer 1

今天我遇到了类似的问题。我使用TensorFlowLite_ES32库而不是Arduino_TensorFlowLite解决了这个问题。您需要下载此库并添加#include<TensorFlowLite_ES32.h>。我希望这也能帮助你

Answer 2

我现在通过从Arduino框架切换到ESP-IDF框架来解决这个问题。有了这个，它就像一种魅力。
