While this file was originally intended for Python 2 -> 3 transition, it is now used to create a compatibility layer between different minor versions of Python 3. While the active version of numpy may not support a given version of python, we allow downstream libraries to continue to use these shims for forward compatibility with numpy while they transition their code to newer versions of Python. )bytesasbytes isfileobj getexceptionstrcharunicode asunicodeasbytes_nestedasunicode_nestedasstr open_latin1long basestringsixu integer_typesis_pathlib_pathnpy_load_modulePathpicklecontextlib_nullcontext os_fspath os_PathLikeN)rcCt|tr |dSt|SNlatin1 isinstancerdecodestrsr!t|tjtjtjfs dSz|WdStyYdSw)NFT)rr&r'r(r)filenoOSErrorr*r!r!r" _isfileobj4s r.rcCst||ddS)Nz iso-8859-1)modeencoding)open)filenamer0r!r!r"r ?sr cCs|Sr%r!rr!r!r"rBrUcCs tdS)N)sysexc_infor!r!r!r"rGs rcC.t|drt|ttfsdd|DSt|S)N__iter__cSg|]}t|qSr!)r.0yr!r!r" Lz"asbytes_nested..)hasattrrrrrxr!r!r"rJrcCr9)Nr:cSr;r!)r r<r!r!r"r?Rr@z$asunicode_nested..)rArrrrrBr!r!r"r PrDr cCs t|tS)z Check whether obj is a `pathlib.Path` object.
