要在C语言中调用TensorFlow模型,可以使用TensorFlow C API。以下是一个简单的示例代码:
#include <stdio.h> #include <tensorflow/c/c_api.h> int main() { TF_Graph* graph = TF_NewGraph(); TF_Status* status = TF_NewStatus(); // Load the SavedModel TF_SessionOptions* session_options = TF_NewSessionOptions(); TF_Buffer* run_options = NULL; const char* tags = "serve"; int ntags = 1; TF_Session* session = TF_LoadSessionFromSavedModel(session_options, run_options, "path_to_saved_model", &tags, ntags, graph, NULL, status); if (TF_GetCode(status) != TF_OK) { fprintf(stderr, "Error loading model: %s\n", TF_Message(status)); return -1; } // Create input tensor const int64_t dims[2] = {1, 784}; TF_Tensor* input_tensor = TF_AllocateTensor(TF_FLOAT, dims, 2, 784 * sizeof(float)); // Fill input tensor with data // Create output tensor TF_Output output; output.oper = TF_GraphOperationByName(graph, "output"); output.index = 0; TF_Tensor* output_tensor = TF_NewTensor(TF_FLOAT, dims, 2, 10 * sizeof(float), data, 10, &noop_deallocator, 0); // Run the session TF_Tensor* outputs[1] = {output_tensor}; TF_SessionRun(session, NULL, NULL, &input_tensor, outputs, 1, NULL, 0, NULL, 0, NULL, status); if (TF_GetCode(status) != TF_OK) { fprintf(stderr, "Error running model: %s\n", TF_Message(status)); return -1; } // Get the output values float* output_data = TF_TensorData(output_tensor); for (int i = 0; i < 10; i++) { printf("Output value %d: %f\n", i, output_data[i]); } // Clean up TF_CloseSession(session, status); TF_DeleteSession(session, status); TF_DeleteSessionOptions(session_options); TF_DeleteGraph(graph); TF_DeleteStatus(status); return 0; }
请注意,这只是一个简单的示例代码,实际使用时需要根据自己的模型和数据进行适当的修改。另外,需要确保正确链接TensorFlow C库和头文件。
