I am training a pretty intensive ML model using a GPU and what will often happen that if I start training the model, then let it train for a couple of epochs and notice that my changes have not made a significant difference in the loss/accuracy, I will make edits, re-initialize the model and re-start training from epoch 0. In this case, I often get OOM errors.
My guess is that despite me overriding all the model variables something is still taking up space in-memory.
Is there a way to clear the memory of the GPU in Tensorflow 1.15 so that I don't have to keep restarting the kernel each time I want to start training from scratch?
It depends on exactly what GPUs you're using. I'm assuming you're using NVIDIA, but even then depending on the exact GPU there are three ways to do this-
nvidia-smi -r
works on TESLA and other modern variants. nvidia-smi --gpu-reset
works on a variety of older GPUs.
