在尝试将NumPy数组转换为张量(tensor)时遇到“unsupported object type int”错误,通常意味着NumPy数组中的数据类型不是张量库(如PyTorch或TensorFlow)所期望的。基于你提供的提示,我将逐步解释如何解决这个问题。 1. 确认NumPy数组的数据类型 首先,我们需要检查NumPy数组的数据类型。这可以通过numpy.ndarray.dtype属性来...
🐛 Bug I compared the execution time of two codes. Code 1: import torch import numpy as np a = [np.random.randint(0, 10, size=(7, 7, 3)) for _ in range(100000)] b = torch.tensor(np.array(a)) And code 2: import torch import numpy as np a =...
Use Tensor.cpu(),我尝试将 intrinsic_normal 改成 intrinsic_normal.cuda().data.cpu().numpy(),继续报新的错: 'numpy.ndarray' object has no attribute 'cuda' 参考'numpy.ndarray' object has no attribute 'cuda' , 将 intrinsic_normal 转化成tensor类型 intrinsic_normal = torch.tensor(intrinsic_...
'numpy.ndarray' object has no attribute 'cuda' 1. 参考'numpy.ndarray' object has no attribute 'cuda', 将 intrinsic_normal 转化成tensor类型 intrinsic_normal = torch.tensor(intrinsic_normal).cuda().data.cpu().numpy() 1. 成功解决
TypeError:can't convertCUDAtensor to numpy.Use Tensor.cpu()to copy the tensor to host memory first. 意思是:如果想把CUDA tensor格式的数据改成numpy时,需要先将其转换成cpu float-tensor随后再转到numpy格式。 numpy不能读取CUDA tensor 需要将它转化为 CPU tensor 将predict.data.numpy()改为predict.data...
