In DataLoader2Iterator:
def __getattr__(self, name):
"""
To delegate operations to ``dataloader._datapipe_iter``.
"""
if self.dataloader._datapipe_iter is None:
raise AttributeError
return getattr(self.dataloader._datapipe_iter, name)I'm not sure exactly how, but this seems to get into some infinite recursion.
This is via the PyCharm debugger. The PyCharm debugger dynamically calls dir and getattr on some objects to visualize them. Likely it tried to access some attrib, which caused this.
