the update time of iteration is so slow, so i check forward time, calculating loss time and backward time. And i get this.
forward time : 0.09247469902038574
loss time : 0.19421815872192383
backward time : 0.9493999481201172
the backward time is more than 10 times the forward time. Do you know why this is happening?
