深度学习--np.meshgrid(a,b)和torch.meshgrid(x,y)

结论：
np.meshgrid(a,b)是按a作为x轴信息，b为y轴信息;
torch.meshgrid(x,y)是按输入x作为y轴信息，输入y作为x轴信息.。

import torch
import numpy as np

# 通过一下代码可以生成一个网格，每一个网格点是对应的一个中心点，数值从32~224，如果是整张图的范围的话是0~256
stride = 8
w = 25
h = 25

# tensor([  0.,   8.,  16.,  24.,  32.,  40.,  48.,  56.,  64.,  72.,  80.,  88.,
#          96., 104., 112., 120., 128., 136., 144., 152., 160., 168., 176., 184.,
#         192.])
x_tensor = torch.arange(0, w * stride, step=stride, dtype=torch.float32)
x_np = np.arange(0, w * stride, step=stride, dtype=np.float32)
y_tensor = torch.arange(0, h * stride, step=stride, dtype=torch.float32)
y_np = np.arange(0, h * stride, step=stride, dtype=np.float32)
print(x_tensor)
print(x_np)
# 生成网格
y_tensor, x_tensor = torch.meshgrid(y_tensor, x_tensor)  # 一行一行
y_np, x_np = np.meshgrid(y_np, x_np)  # 一列一列

# 将矩阵转成向量
x_np = x_np.reshape(-1)
y_np = y_np.reshape(-1)
x_tensor = x_tensor.reshape(-1)
y_tensor = y_tensor.reshape(-1)

# torch.Size([625, 2])
# 网格的坐标从32~224，网格的坐标值的是中心点的坐标每一个网格长度是34
location_tensor = torch.stack((x_tensor, y_tensor), dim=1) + 32
location_np = np.stack((x_np, y_np), axis=1) + 32
print('tensor:', location_tensor.shape, '\n    np:', location_np.shape)

for tensor_xy, np_xy in zip(location_tensor, location_np):
    print('tensor:', tensor_xy, '\tnp:', np_xy)

打印结果：

将y_np, x_np = np.meshgrid(y_np, x_np)修改成x_np, y_np = np.meshgrid(x_np, y_np);这样两个的输出就可以是一样的了
