As reported in Debian Bug #1110711, a few tests fail with pyshp 3.0.0:
Traceback (most recent call last):
File "/tmp/autopkgtest-lxc.j0rpiwrc/downtmp/autopkgtest_tmp/hurrtracks.py", line 17, in <module>
shp_info = m.readshapefile('huralll020','hurrtracks',drawbounds=False)
File "/usr/lib/python3/dist-packages/mpl_toolkits/basemap/__init__.py", line 2152, in readshapefile
bbox = shf.bbox.tolist()
^^^^^^^^^^^^^^^
AttributeError: 'tuple' object has no attribute 'tolist'
Full output: https://ci.debian.net/packages/b/basemap/unstable/amd64/62754867/
From the pyshp README:
- bbox, mbox and zbox attributes are all new Namedtuples.
