LookupError: No gradient defined for operation 'ENet/bottleneck2_0_main_max_pool' (op type: MaxPoolWithArgmax)

When I run ./train.sh, I find this error. Is this because of the Tensorflow version or I need to define the gradient of ENet/bottleneck2_0_main_max_pool myself?
Thx!
Are you using a TF version lesser than r1.2? In r1.1 and below the gradient for this argmax isn't defined but this was fixed in r1.2.
@kwotsin Thx! I did not update TF for a long time ....Let me see it .
