A issues about memory leak

[gxl2024595]

i add a viewcontroller which as the first vc in MobileNetsDemo.Then present the cameracontroller in demo ,and then dismiss the cameracontroller .But i find that when i do this ,there is about 10M memory is not released.And everytime i present the cameracontroller ,there is more 10M in memory which is not released. i guess the issues is everytime createNeuralNetwork the memory will in increase，but i cannot solve the problem.How could i solve this problem??

You can use Instruments with the Allocations instrument to find out exactly where that extra 10MB comes from.

when call this function ,the memory will increase,and when i dismiss the cameracontroller ,the extra 10MB would not be released

Could you try to add a viewcontroller in your demo(MobileNets) ,and you can present the cameratroller and dismiss the cameratroller for sereval times.You will find the same issues.Please help me Great God^^

It's definitely not a good idea to create the neural network every time. Just create it once and keep re-using it.

But,if i want to swich the training model ,i have to create the neural network again.Is there any way to swich the training model without creating the neural network again？

[hollance]

At this point, no. There is no way to change the weights after you've created the model. So in that case you do have to create the neural network again.

Ok, i get it.Thanks.

@gxl2024595 I fixed the memory leak. Give it a try and see if it works for you.
