Hi Zhengzheng,
I don’t know python either, but maybe you just need to get a newer Chimera.  I tried the production release (1.13) and a recent daily build (1.14) and I did not see any error message when opening your PDB file.  

I do see some warnings in Reply Log (open from Favorites menu) like this:
warning: cannot find LINK/SSBOND residue  ZN (953 )

… but it is probably just because the header information in the first part of the file refers to the other chains that I assume you had deleted from the structure.  In that case the warning messages are expected and could be ignored.
