What am i doing wrong ?

Answer 1 · 2022-09-13T08:22:31.000Z

Please make sure you're:

using a C++14-compatible compiler (and have enabled that language version).
using the latest version of FunctionalPlus (and frugally-deep).

Answer 2 · 2022-09-13T08:24:38.000Z

Ok, in your command (clang++ [...] -std=c++20 [...]), the C++ version seems ok. So please try updating FunctionalPlus, and let know if that helped. 🙂

Answer 3 · 2022-09-13T08:47:19.000Z

Both fplus and frugally-deep, are up to date.

Answer 4 · 2022-09-13T08:52:48.000Z

-I../libs/fplus/fplus/include might be wrong (double fplus). But I of course don't know where you have your files. 🙂

I suggest you try to minimize the problem, by throwing everything out which is not essential to reproducing this compilation error, e.g., your custom code, and other libs like OpenCV, etc.

And then maybe try to compile manually, i.e., without ninja, also for example with -std=c++14 instead of -std=c++20, or with g++ instead of clang.

I guess somewhere on this path, you'll find the cause.

Answer 5 · 2022-09-14T15:08:10.000Z

ok my bad. i was using wrong repo for functional plus. it was some outdated fork that came up in google search.

Answer 6 · 2022-09-15T05:30:20.000Z

i used a premade .h5 model from teachablemachine and converted it to .json in colaboratory

When trying to use it with fdeep :

Loading json ... done. elapsed time: 0.008460 s
[json.exception.type_error.302] type must be string, but is null

here is the model i used : test_model.zip

Answer 7 · 2022-09-15T06:12:37.000Z

Please make sure you are using the latest versions of TensorFlow and Keras, and then re-run the convert_model call. 🙂

Answer 8 · 2022-09-17T07:39:59.000Z

@0xb00b Ah, I just see you tried to load some arbitrary .json file using frugally-deep. This won't work. It has to be a .json file that was created using convert_model.py from frugally-deep/keras_export (as described in the docs).

Answer 9 · 2022-09-17T12:17:09.000Z

oh! thanks, it works now. I had mistaken .json file as tensorflow.js model, since both use json.

fdeep really removes the pain of linking to tensorflow. thanks for this project again.
