Question

我收到了错误：

TypeError: 'float' object cannot be interpreted as an integer

当我致电maskoceans时。为什么是这样？我正在运行python3。

from mpl_toolkits.basemap import Basemap
from mpl_toolkits.basemap import maskoceans
from mpl_toolkits.basemap import interp
from scipy.interpolate import griddata
import matplotlib.pyplot as plt
import numpy as np

places = {
(-8.91508040128176, 52.23826465): 0,
(-6.45854802816101, 52.64127685): 21,
(-9.03867527891856, 52.78809005): 0,
(-8.70926037608263, 53.717247): 0,
(-6.8217677, 54.3303964): 0,
(-6.1658125, 53.5255827): 4
}

m = Basemap(llcrnrlon=-10.56, llcrnrlat=51.39, urcrnrlon=-5.34, urcrnrlat=55.43,
               lat_1=30., lat_2=60., lat_0=53.41, lon_0=-7.95, 
              resolution="i")

x, y, values = np.array([(x, y, v) for (x, y), v in places.items()]).T
coords = np.stack((x, y)).T

x, y = np.mgrid[-11:-4:10j, 51:56:10j]
z = griddata(coords, values, (x, y), method='nearest')

mdata = maskoceans(x, y, z, resolution = 'h', grid = 10, inlands=True)

plt.contour(x[:,0], x[0,:], mdata.T,linewidths=0.5,colors='k',z=99)
plt.contourf(x[:,0], y[0,:], mdata.T,cmap=plt.cm.Purples, z=100)

这是完整的堆栈跟踪：

    mdata = maskoceans(x, y, z, resolution = 'h', grid = 10, inlands=True)

如果您使用Python3，则需要对此文件进行简单的更改：

“your_python3_install_directory / LIB / python3.x /站点包/ mpl_toolkits /底图/的初始化 py” 为

在第5125行和第5130行之间，找到“nlats = nlons / 2”并将其更改为“nlats = nlons // 2”。

这应该可以解决问题。
