转换成onnx用c++会报错

[Jialeen]

我自己转换模型，然后用c++实现前向会报错：
Non-zero status code returned while running Split node. Name:'/roi_heads/Split_3' Status Message: Cannot split using values in 'split' attribute. Axis=0 Input shape={240,7} NumOutputs=1 Num entries in 'split' (must equal number of outputs) was 1 Sum of sizes in 'split' (must equal size of selected axis) was 256

请问下你这是怎么转的？
