Anyone know where this library is, which can only be used on esp32s3 cam lcd?

Arduino/libraries/EloquentEsp32cam/src/eloquent_esp32cam/face/detection.h:4:10: fatal error: human_face_detect_mnp01.hpp: No such file or directory
    #include "human_face_detect_mnp01.hpp"

I have a "portable" installation of IDE v1.8.19. Those files are in:
D:\arduino-1.8.19\portable\packages\esp32\tools\esp32-arduino-libs\idf-release_v5.1-632e0c2a\esp32s3\include\espressif__esp-dl\include\model_zoo

@gfvalvo

Could that depend on the version of the ESP32 board package? I have version 3.1.0 installed and the path for the idf_release_vxx is slightly different (C:\Users\bugge\AppData\Local\Arduino15\packages\esp32\tools\esp32-arduino-libs\idf-release_v5.3-083aad99-v2\esp32s3\include) and in there is no directory espressif__esp-dl.

And in my portable install (ESP32 version 2.0.7) the tools\esp-arduino-libs does not exist.

Note:
Just asking for OP.

Can the library be found, I've searched for information but can't find anything

5

I wouldn't doubt it.

Which brings the question which version you have installed :wink:

7

there is no this folder

8

The operating system of your computer will have these down as "hidden" folders. You need to enable the feature in your computer that shows hidden stuff.

idf-release_v5.1-632e0c2a is v3.0.7. On Linux

~$ cd ~/.arduino15/packages/esp32
~/.arduino15/packages/esp32$ ls hardware/esp32
3.0.7
~/.arduino15/packages/esp32$ ls tools/esp32-arduino-libs/
idf-release_v5.1-632e0c2a
~/.arduino15/packages/esp32$ find tools/esp32-arduino-libs -name human_face_detect_mnp01.hpp

Files are available for three variants: ESP32, -S2, and -S3

All files and folders that start with a dot are hidden by default. On Mac, the Arduino15 directory is under ~/Library, also a hidden folder. So instead you start with

$ cd ~/Library/Arduino15/packages/esp32

On Windows, it's under the hidden AppData directory in your home folder. And there's no find; instead

PS > cd $env:LOCALAPPDATA\Arduino15\packages\esp32
PS > Get-ChildItem tools\esp32-arduino-libs -Recurse -Filter human_face_detect_mnp01.hpp

It seems that in v3.0.7 these files were there, then starting from 3.1.0 they disappeared for some reasons. I have the same issue. Reverting to 3.0.7 solved the problem. I don't know if there is a patch to use the latest lib version which is 3.3.1.
