/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/tensorflow/python/ops/gen_array_ops.py
第17行 从tensorflow.python.framework导入op_def_library为 _op_def_library第33行 result = _op_def_lib .apply_op(“BatchMatrixBandPart”,input = input,num_lower = num_lower,num_upper = num_upper,name = name)
第33行如何调用_op_def_lib而第17行定义为_op_def_library?
