Describe
支持方程初始化时指定
detach_keys，使得梯度不会通过这些key对应的变量反向传播，并添加对应单测。graph TD; x & y-->u & v; x & u-->u__x; y & v-->v__y; u__x & u --> o1; v__y & v --> o2; o1 & o2 --> z;当
detach_keys为("u", "v__y")时，计算关系会变为下图（新增两条detach路径）。graph TD; x & y-->u & v; x & u-->u__x; y & v-->v__y; u --> |detach| u_detach([u_detach]); u__x & u_detach --> o1; v__y --> |detach| v__y_detach([v__y_detach]); v__y_detach & v --> o2; o1 & o2 --> z;
