howto plt.subplots (projection='3d')?

Any way to use plt.subplots for 3d?

This doesn't work:
  fig, axs = plt.subplots(nrows=opt.rcv_paths, ncols=1, sharex=True,
subplot_kw=dict(projection='3d'))
...
  File "/home/nbecker/.local/lib/python3.6/site-
packages/matplotlib/projections/__init__.py", line 67, in
get_projection_class
    raise ValueError("Unknown projection '%s'" % projection)
ValueError: Unknown projection '3d'

You have to import the mplot3d toolkit first. That causes the 3d projection
to get registered.
