Keras猫狗大战十:输出Resnet50分类热力图 图像分类识别中,可以根据热力图来观察模型根据图片的哪部分决定图片属于一个分类。 以前面的Resnet50模型为例:https://www.cnblogs.com/zhengbiqing/p/11964301.html 输出模型结构为: model
model = ImageRetrievalNet() # # 定义一个 PyTorch 张量来模拟输入数据 # batch_size = 4 # 定义批处理大小 # input_shape = (batch_size, 3, 224, 224) # input_data = torch.randn(input_shape) # # 将模型转换为 ONNX 格式 # output_path = "resnet50.onnx" ...
Code Issues Pull requests This project uses a pre-trained ResNet50 model from the FastAI library to detect pneumonia in chest X-rays. The dataset which is available on kaggle is used for training the model which classifies the chest xray as NORMAL, VIRAL or BACTERIAL and this project is dep...
