I was trying to run Mask rcnn on tensorflow, TF GPU is installed on my jetson nano. This low memory Waring pops up regularly, though I used swapfile to 8G still dint help. ??

Thank you

I tried converting .pb file to Tensor RT on jetson nano, i ran into error which is given below. i have used Accelerating Inference In TF-TRT User Guide :: NVIDIA Deep Learning Frameworks Documentation for this convertion.

I tried with saved model but this jetson nano gives this memory warning n turns off. The main aspect o fmy project is MASK RCNN. It has been 4 weeks we got this jetson nano n couldnt run a MaskRcnn inference even once. Every method we tried failed, we are not able to get any opensource solutions yet. I request you to support us ASAP.!
