Proposals to improve the examples

idata · ‎11-24-2017

Hi.

I have started testing the sdk and I have verified that there is an example that does not match the version of cpp and python.

The cpp example of googlenet/Alexnet/SqueezeNet has less functionality than phyton example.

This is my proposal.

Insert in line 39 this code

// Labels family
#define LABELS_FILE_NAME "../../../data/ilsvrc12/synset_words.txt"

After de code "fp16tofloat(resultData32, (unsigned char*)resultData16, numResults);", replace from line 213 to the end whit this code.

                // load labels
                char category[100];
                char *content = 0;
                char *labels[1000];
                for(int i = 0; i < 1000; i++){
                    labels[i] = 0;
                }

                FILE *f = fopen(LABELS_FILE_NAME, "rb");
                if(f != NULL){
                    fseek(f, 0, SEEK_END);
                    size_t size = ftell(f);
                    rewind(f);
                    content = (char *)malloc(sizeof(char)*(size + 1));
                    if (content != NULL){
                        size_t read;
                        read = fread(content, sizeof(char), size, f);
                        fclose(f);
                        if(size == read){ 
                            content[size] = 0;
                            char * content2 = content;
                            char *token;
                            int pos = 0;
                            while ((token = strsep(&content2, "\n")) != NULL && pos < 1000){
                                labels[pos++] = token + 10;
                            }
                        } 
                    }
                }

                int *results = NULL;
                int totalSizeResults = 10;
                int sizeResults = 0;
                results = (int *)malloc(sizeof(int) * totalSizeResults);
                if(results != NULL){

                    // we ignore all those that give a value 0
                    for (int index = 0; index < numResults; index++){
                        if (resultData32[index] > 0){
                            if(sizeResults == totalSizeResults){
                                totalSizeResults = sizeResults + 10;
                                results = (int*) realloc (results, totalSizeResults * sizeof(int));
                                if(results == NULL){
                                    --sizeResults;
                                    break;
                                }
                            }

                            }
                        }
                    }                

                    // we show the categories
                    for(int i=0, limiteI = sizeResults; i < limiteI; i++){
                        printf("Category %d - %s is: %f\n", results[i], 1000 > results[i]?labels[results[i]]:"", resultData32[results[i]]);
