Spresense SDK - Tensorflow : Flatbuffers missing

[Arco]

@KamilTomaszewski Thank for your help I own you one

Do you think that another solutions like CircuitPython or MicroEJ would be better for using TensorFlow ?

Thank you again

[KamilTomaszewski]

@Arco You're welcome.

Unfortunately, TensorFlow is currently only supported on the NuttX SDK.

Hello @KamilTomaszewski

after a while I came back to this issue.
I tried to create new project inside of /spresense/examples (same as tf_examples). I was following whole structure of tf_examples from Makefile, Kconfig to creating configuration files in /spresense/sdk/examples/.

I have launched ( hlasove_povely is name of the project )

$ tools/config.py hlasove_povely

and after that

$ make

But I am getting this output :

make[6]: *** No rule to make target `context'.  Stop.
make[5]: *** [hlasove_povely_context] Error 2
make[4]: *** [../examples/_context] Error 2
make[3]: *** [/Users/arcius/C++/Sony-Spresense/spresense/sdk/apps/.._context] Error 2
make[2]: *** [context_serialize] Error 2
make[1]: *** [context] Error 2
make: *** [all] Error 2

Am I something missing thanks

Right now after calling :

tools/config.py hlasove_povely

the response is :

make[6]: *** No rule to make target `preconfig'.  Stop.
make[5]: *** [Kconfig] Error 2
make[4]: *** [../examples/_preconfig] Error 2
make[3]: *** [preconfig] Error 2
make[2]: *** [Kconfig] Error 2
make[1]: *** [apps_preconfig] Error 2
make: *** [olddefconfig] Error 2
Post process failed. 512
Try 'make distclean' first.

(I tried 'make distclean' but didn't help)

Thanks

Hi @Arco

Do you include in your Makefile: include $(APPDIR)/Application.mk

The error could be because it is missing.

[Arco]

@KamilTomaszewski
Yes I do.

Makefile :

-include $(TOPDIR)/Make.defs
-include $(SDKDIR)/Make.defs

PROGNAME = $(CONFIG_EXAMPLES_HLASOVE_POVELY_PROGNAME)
PRIORITY = $(CONFIG_EXAMPLES_HLASOVE_POVELY_PRIORITY)
STACKSIZE = $(CONFIG_EXAMPLES_HLASOVE_POVELY_STACKSIZE)
MODULE = $(CONFIG_EXAMPLES_HLASOVE_POVELY)

MAINSRC = hlasove_povely_main.c

include $(APPDIR)/Application.mk

Make.defs :

ifneq ($(CONFIG_EXAMPLES_HLASOVE_POVELY),y)
CONFIGURED_APPS += hlasove_povely
endif

Kconfig :

config EXAMPLES_HLASOVE_POVELY
	tristate "Tensorflow Example app"
	default n
	---help---
		Enable the NuttX command line application for executing example of
		Tensorflow lite micro.

if EXAMPLES_HLASOVE_POVELY

config EXAMPLES_HLASOVE_POVELY_PROGNAME
	string "Program name"
	default "hlasove_povely"
	---help---
		This is the name of the program that will be use when the NSH ELF
		program is installed.

config EXAMPLES_HLASOVE_POVELY_PRIORITY
	int "hlasove_povely task priority"
	default 100

config EXAMPLES_HLASOVE_POVELY_STACKSIZE
	int "hlasove_povely stack size"
	default 32768

endif

Hi @Arco

Could you try to create a new example using this command:

sdk$ ./tools/mkcmd.py hlasove_povely

[Arco]

@KamilTomaszewski

Response is :

hlasove_povely already exists

[KamilTomaszewski]

@Arco

Delete or move your old example out of sdk and create a new one using this command.

[KamilTomaszewski]

@Arco Another thing I noticed in your example is incorrect code in Make.defs:

ifneq ($(CONFIG_EXAMPLES_HLASOVE_POVELY),y)
CONFIGURED_APPS += hlasove_povely
endif

It should be:

ifeq ($(CONFIG_EXAMPLES_HLASOVE_POVELY),y)
CONFIGURED_APPS += hlasove_povely
endif

ifneq -> ifeq

[Arco]

Thanks @KamilTomaszewski, you saved me once again !
Have a nice day ! ( make is working )

Hey @arco

I am trying to create a new Tensorflow lite micro application based on image classification similar to the (/spresense/examples/tflmrt_lenet application) and deploy it on Spresense. Could you please share the steps to be followed to create the application?

Any kind of help is highly appreciated

Thanks in advance

Can you share the structure (the make, kconfig and so on..) (or any link/resource that mentions it) that you followed (which you have mentioned here) ?

Thanks
