如果您使用 C++,您可能需要使用 C++ API。这标签图像示例 https://github.com/tensorflow/tensorflow/tree/master/tensorflow/examples/label_image可能是帮助您开始的一个很好的示例。
如果您确实只想使用 C API,请使用TF_GraphImportGraphDef https://github.com/tensorflow/tensorflow/blob/e8f2aad/tensorflow/c/c_api.h#L805加载图表。请注意,C API 使用起来并不是特别方便(它旨在用其他语言(例如 Go、Java、Rust、Haskell 等)构建绑定。)例如:
#include <stdio.h>
#include <stdlib.h>
#include <tensorflow/c/c_api.h>
TF_Buffer* read_file(const char* file);
void free_buffer(void* data, size_t length) {
free(data);
}
int main() {
// Graph definition from unzipped https://storage.googleapis.com/download.tensorflow.org/models/inception5h.zip
// which is used in the Go, Java and Android examples
TF_Buffer* graph_def = read_file("tensorflow_inception_graph.pb");
TF_Graph* graph = TF_NewGraph();
// Import graph_def into graph
TF_Status* status = TF_NewStatus();
TF_ImportGraphDefOptions* opts = TF_NewImportGraphDefOptions();
TF_GraphImportGraphDef(graph, graph_def, opts, status);
TF_DeleteImportGraphDefOptions(opts);
if (TF_GetCode(status) != TF_OK) {
fprintf(stderr, "ERROR: Unable to import graph %s", TF_Message(status));
return 1;
}
fprintf(stdout, "Successfully imported graph");
TF_DeleteStatus(status);
TF_DeleteBuffer(graph_def);
// Use the graph
TF_DeleteGraph(graph);
return 0;
}
TF_Buffer* read_file(const char* file) {
FILE *f = fopen(file, "rb");
fseek(f, 0, SEEK_END);
long fsize = ftell(f);
fseek(f, 0, SEEK_SET); //same as rewind(f);
void* data = malloc(fsize);
fread(data, fsize, 1, f);
fclose(f);
TF_Buffer* buf = TF_NewBuffer();
buf->data = data;
buf->length = fsize;
buf->data_deallocator = free_buffer;
return buf;
}
