[IMP-users] IMP.atom.read_pdb confusing error message when not finding file

When trying to read a pdb file that does not exist on my disk I get a puzzling message :

mh = IMP.atom.read_pdb(pdbFilePath,m,sel) NotImplementedError: Wrong number of arguments for overloaded function 'read_pdb'. Possible C/C++ prototypes are: IMP::atom::read_pdb(IMP::TextInput,IMP::Model *) IMP::atom::read_pdb(IMP::TextInput,IMP::Model *,IMP::atom::PDBSelector const &,bool) IMP::atom::read_pdb(IMP::TextInput,IMP::Model *,IMP::atom::PDBSelector const &)
