@fcholletCan you also please help. I am looking to save the weights so that I can create the image after the convolutions. I used model.save_weights to save a hdf5 file. But I am unable to convert that into a numpy array and save it as an image. ...

访问tensor中的数据类似于NumPy array。torch.cat方法可以将tensor按指定维度进行拼接。单元素tensor可通过其item()方法获取python中的数值。带有后缀"_"的操作为in-place操作,即使用结果来更新操作数,这样可以节省内存空间,但同时会丢失历史数据。 在CPU上,tensor和 Numpy array可以相互转换并共享底层内存,因此,改变其中...
