The body of the with-context is lifted into a function that is compiled in *object-mode*. This transformation process is limited and cannot process all possible Python code. However, users can wrap complicated logic in another Python function, which will then be executed by the interpreter. Use this as a function that takes keyword arguments only. The argument names must correspond to the output variables from the with-block. Their respective values are strings representing the expected types. When exiting the with-context, the output variables are cast to the expected nopython types according to the annotation. This process is the same as passing Python objects into arguments of a nopython function. Example:: import numpy as np from numba import njit, objmode def bar(x): # This code is executed by the interpreter. return np.asarray(list(reversed(x.tolist()))) @njit def foo(): x = np.arange(5) y = np.zeros_like(x) with objmode(y='intp[:]'): # annotate return type # this region is executed by object-mode. y += bar(x) return y .. note:: Known limitations: - with-block cannot use incoming list objects. - with-block cannot use incoming function objects. - with-block cannot ``yield``, ``break``, ``return`` or ``raise`` such that the execution will leave the with-block immediately. - with-block cannot contain `with` statements. - random number generator states do not synchronize; i.e. nopython-mode and object-mode uses different RNG states. .. note:: When used outside of no-python mode, the context-manager has no effect. .. warning:: This feature is experimental. The supported features may change with or without notice. cCs·|dkriSt|dƒdkr8tjdƒ‚n|d}i}xh|jƒD]Z\}}t|tjƒ s‡t|jt ƒ r™tjdƒ‚nt j |jƒ||ês R:R;R<t objectmodet output_types(RXRTR/RR0R=tlisttmapRt TypingErrortformatRtTupleR>R?R@RARBRCR'(RRRRRRRRRVR4RDRERZt stripped_outstextra_annotatedtmsgt not_annotatedRWtouttupRFRGRHRI((Rs1lib/python2.7/site-packages/numba/withcontexts.pyRÅsD   &         cOs|S(N((RRKRL((s1lib/python2.7/site-packages/numba/withcontexts.pyt__call__s(RRRRBRRXRRg(((s1lib/python2.7/site-packages/numba/withcontexts.pyRJxs 2  ;c Csµ||}|j}|j}tjd|d|ƒ}xQ|jƒD]C\}} |jtjd|j|ƒd|j| ƒd|ƒƒqAW|jtjd|d|ƒƒ|||8s       N(tnumbaRRRRRtnumba.typing.typeofRt transformsRtobjectRtregisterRR$R'R(tbypass_contextR6t call_contextRJtobjmode_contextR3RCR>(((s1lib/python2.7/site-packages/numba/withcontexts.pyts(  (
