[fastback407]

Hi guys,

It'll be great help if you could support user documents about capi.

Thanks.

Can this README.md help you?

Is there any documents about the apis such as paddle_matrix_create_sparse()?
If I have 2 slot, and 1 is binary, how to combine them, and how to get the predict result?

Sorry, there is no document at present, but most api has annotations. paddle_matrix_create_sparse

Here is an example of how to use capi inference. Where the ./trainer_config.bin file is converted from the training file by convert_protobin.sh.

Thanks, but what does '10' means in this loop:
printf("Prob: ");
for (int i = 0; i < 10; ++i) {
printf("%.2f ", array[i]);
}
Where could I get it?

[hedaoyuan]

The number 10 comes from here, is the output size of the trainer_config.py.
And the trainer_config.bin in the demo is converted from trainer_config.py.

how to config trainer_config.py?

[hedaoyuan]

trainer_config.py is the configuration file used for training.
You can refer to the example inside tutorials.
