Pyotb 1.4.1 has introduced a bug

from scenes import spot

sc = spot.Spot67Scene(dimap_file_xs='DIM_SPOT6_MS_201503261014386_ORT_SPOT6_20170524_1422391k0ha487979cy_1.XML', dimap_file_pan='DIM_SPOT6_P_201503261014386_ORT_SPOT6_20170524_1422391k0ha487979cy_1.XML')
xs = sc.get_xs()
print(hasattr(xs, 'shape'))  # prints False
xs.shape  # Raises exception

Exception raised:

Traceback (most recent call last):
  File "/home/otbuser/.local/lib/python3.8/site-packages/pyotb/core.py", line 245, in __getattr__
    res = getattr(self.app, name)
  File "/opt/otbtf/lib/otb/python/otbApplication.py", line 2833, in __getattr__
    raise AttributeError("'%s' object has no attribute '%s'" % (Application.__name__, name))
AttributeError: 'Application' object has no attribute 'shape'

The above exception was the direct cause of the following exception:
