用python画风场图时出现如下错误
import numpy
from metpy.units import units
from scipy.ndimage import gaussian_filter
data = xr.open_dataset('presure2020.nc').metpy.parse_cf()
u=data['u'][0,0,:,:]
v=data['v'][0,0,:,:]
q1=data['r'][0,:,:,:]
lon = data['longitude']
lat= data['latitude']
lon,lat =np.meshgrid(lon,lat)
fig = plt.figure(figsize=(10, 5))
ax = fig.add_subplot(1, 1, 1, projection=ccrs.PlateCarree())
ax.set_extent([0, 140, 10, 85], crs=ccrs.PlateCarree())
ax.coastlines()
magnitude = (u ** 2 + v ** 2) ** 0.5
ax.streamplot(lon, lat, u, v, transform=ccrs.PlateCarree(),
linewidth=2, density=2, color=magnitude)
plt.show()
fig = plt.figure(figsize=(10, 5))
ax = fig.add_subplot(1, 1, 1, projection=ccrs.PlateCarree())
ax.set_extent([0, 140, 10, 85], crs=ccrs.PlateCarree())
ax.coastlines()
# x, y, u, v, vector_crs = sample_data(shape=(80, 100))
magnitude = (u ** 2 + v ** 2) ** 0.5
ax.streamplot(lon, lat, u, v, transform=ccrs.PlateCarree(),
linewidth=2, density=2, color=magnitude)
plt.show()
错误如下:
AttributeError: 'DataArray' object has no attribute 'ravel'求助,我找了好久就是不知道问题出在哪里了。求助
