Basemap issue for Debian 11 testing

[Bu Kun]

I have been used Debian as GIS platform for years. Thanks to Debian.

Yesterday I began to test the codes of my book (Python and Open Source GIS) 
under Debian 11 testing.  https://github.com/bukun/book_python_gis
Now I found an issue.  And a similar link 
: https://stackoverflow.com/questions/65668542/projerror-x-y-z-and-time-must-be-same-size 


As follows codes:


-------------------------------------------------------------------------------------------------------
>>> from mpl_toolkits.basemap import Basemap
>>> para = {'projection': 'tmerc','lat_0': 0,'lon_0': 3,
...     'llcrnrlon': 1.81,
...     'llcrnrlat': 41.58,
...     'urcrnrlon': 1.84,
...     'urcrnrlat': 41.59}
>>>
>>> mymap = Basemap(**para)
Traceback (most recent call last):

Furthermore, i test some other paras. Seems very strange.


Following got same error:


-------------------------------------------------------------------------------------------------------
para = {'projection': 'tmerc','lat_0': 0,'lon_0': 3,
&nbsp; &nbsp; 'llcrnrlon': 1.8,
&nbsp; &nbsp; 'llcrnrlat': 41.5,
&nbsp; &nbsp; 'urcrnrlon': 1.9,
&nbsp; &nbsp; 'urcrnrlat': 41.6}

-------------------------------------------------------------------------------------------------------


Following got no error:


-------------------------------------------------------------------------------------------------------
para = {'projection': 'tmerc','lat_0': 0,'lon_0': 3,
&nbsp; &nbsp; 'llcrnrlon': 1,
&nbsp; &nbsp; 'llcrnrlat': 41,
&nbsp; &nbsp; 'urcrnrlon': 2,
&nbsp; &nbsp; 'urcrnrlat': 42}
para = {'projection': 'tmerc','lat_0': 0,'lon_0': 3,
&nbsp; &nbsp; 'llcrnrlon': 1.8,

&nbsp; &nbsp; 'urcrnrlon': 1.9,
