Insufficient memory problem

[ZiyiZhang0912]

Hi,

I ran into the same problem with #7 when I tried to run the demo:

Begin Training for 5 iterations Traceback (most recent call last): File "C:\ProgramData\Anaconda3\envs\dgp\lib\site-packages\tensorflow\python\client\session.py", line 1334, in _do_call return fn(*args) File "C:\ProgramData\Anaconda3\envs\dgp\lib\site-packages\tensorflow\python\client\session.py", line 1319, in _run_fn options, feed_dict, fetch_list, target_list, run_metadata) File "C:\ProgramData\Anaconda3\envs\dgp\lib\site-packages\tensorflow\python\client\session.py", line 1407, in _call_tf_sessionrun run_metadata) tensorflow.python.framework.errors_impl.ResourceExhaustedError: OOM when allocating tensor with shape[10,512,94,104] and type float on /job:localhost/replica:0/task:0/device:GPU:0 by allocator GPU_0_bfc [[{{node resnet_v1_50/block2/unit_3/bottleneck_v1/conv3/Conv2D}}]] Hint: If you want to see a list of allocated tensors when OOM happens, add report_tensor_allocations_upon_oom to RunOptions for current allocation info.

It is normal to use DLC on my GPU.

I also tried the method mentioned in #7 , adding a few lines of code after line 158 of run_dgp_demo.py:

But the error still did not disappear. I probably understand that the error comes from insufficient memory in CUDA, but I am not sure why this method did not work for me. My understanding of these code is to allow the GPU memory to grow automatically. Did I add it to the correct position?

Hope someone can help me solve this problem, it is very important to me! Thanks for any comments!

Hi,
have you also tried decreasing the batch_size? If not, try adding --batch_size 4 in the console (default is 10).

Thank you very much, I can run after I changed the batch size to 4. But even after I added these lines of code, I still can't use other larger batch sizes, and I still get the same error. But I saw that you mentioned in #7 that after you add these lines of code, you can use batch size =10. So I don't know what caused this result.

Also, have you tried run DLC? you have this memory issue with DLC?

yes，I used DLC and everything goes smoothly without any memory problems.

You mean running DLC with the same data size and the bigger batch size like 10?
