Python Ubuntu 16.04的Matplotlib错误
我有一个Ubuntu 16.04 LTS实例,我正在尝试运行我在Ubuntu 14.04上用python3.5开发的旧脚本。我使用sudo apt get install安装了matplotlib和basemap。这些是我得到的错误Python Ubuntu 16.04的Matplotlib错误,python,matplotlib,python-3.5,matplotlib-basemap,ubuntu-16.04,Python,Matplotlib,Python 3.5,Matplotlib Basemap,Ubuntu 16.04,我有一个Ubuntu 16.04 LTS实例,我正在尝试运行我在Ubuntu 14.04上用python3.5开发的旧脚本。我使用sudo apt get install安装了matplotlib和basemap。这些是我得到的错误 Traceback (most recent call last): File "contour.py", line 30, in <module> x,y = m(lons,lats) File "/usr/lib/python3/dist-packa

这是我正在执行的代码-
nc_f = './hgt_500_2014_12_5_00Z.nc'
nc_fid = Dataset(nc_f, 'r')
# and create an instance of the ncCDF4 class
lats = nc_fid.variables['lat'][:] # extract/copy the data
lons = nc_fid.variables['lon'][:]
time = nc_fid.variables['time'][:]
hgt = nc_fid.variables['hgt'][:]
m = Basemap(width=5000000,height=3500000,
resolution='l',projection='stere', lat_0 = 0, lon_0 = 0, lat_ts = 40)
lons,lats = np.meshgrid(lons, lats,copy=False)
x,y = m(lons,lats) <----- CODE FAILS HERE
m.drawcoastlines()
m.drawcountries()
nc_f='./hgt_500_2014_12_5_00Z.nc'
nc_fid=数据集(nc_f,'r')
#并创建ncCDF4类的实例
lats=nc_fid.变量['lat'][:]#提取/复制数据
lons=nc_fid.变量['lon'][:]
时间=nc_fid.variables['time'][:]
hgt=nc_fid.variables['hgt'][:]
m=底图(宽=5000000,高=3500000,

lons,lats=np.meshgrid(lons,lats,copy=False)
x、 y=m(lons,lats)可能相关:@edwinksl-我看到了这两个答案,我不确定这将如何适用于我的情况。我没有使用pandasCan,您提供的nc_f
小样本再现了您看到的错误?可能与此相关:@edwinksl-我看到了这两个答案,我不确定这将如何适用于我的情况。我没有使用pandasCan,你能提供一个小样本的nc\u f
,重现你看到的错误吗?
