Runtime 推理时,我们尝试使用 4x4 的缩放比例: import onnxruntime input_factor = np.array([1, 1, 4, 4], dtype=np.float32) ort_session...= onnxruntime.InferenceSession("srcnn3.onnx") ort_inputs = {'input': input_img, 'factor': input_factor...} ort_output = ort_session.run(None, ort_inputs)[0] ort_output = np.squeeze(ort_output, 0) ort_output...= np.clip(ort_output, 0, 255) ort_output = np.transpose(ort_output, [1, 2, 0]).astype(np.uint8) cv2....imwrite("face_ort_3.png", ort_output) 运行上面的代码,可以得到一个边长放大4倍的超分辨率图片 "face_ort_3.png"。

onnxruntime-inference-examples/blob/main/c_cxx/imagenet/main.cc 有一个特别坑的地方需要特别的注意: ONNX C++的环境必须是全局变量,声明如下: Ort...::Env env = Ort::Env(ORT_LOGGING_LEVEL_ERROR, "YOLOv5"); 只有所有的推理图象执行完成才可以调用release进行释放,否则就会一直卡死,程序崩溃!
接着刚才的脚本,我们可以添加如下代码运行模型: import onnxruntime ort_session = onnxruntime.InferenceSession("srcnn.onnx")...ort_inputs = {'input': input_img} ort_output = ort_session.run(['output'], ort_inputs)[0] ort_output...= np.squeeze(ort_output, 0) ort_output = np.clip(ort_output, 0, 255) ort_output = np.transpose(ort_output..., [1, 2, 0]).astype(np.uint8) cv2.imwrite("face_ort.png", ort_output) 这段代码中,除去后处理操作外,和 ONNX Runtime 相关的代码只有三行...如果代码正常运行的话,另一幅超分辨率照片会保存在"face_ort.png"中。这幅图片和刚刚得到的"face_torch.png"是一模一样的。
