Fatal Python error: Aborted #11446

Open rohitlal125555 opened 5 years ago

rohitlal125555 commented 5 years ago

Actual Behavior

Python crashes with Fatal Python error: Aborted

Expected Behavior

Should run continuously forever (at least for months without any restart required) with no crash errors.

Detailed Description

I've developed an image processing script that does gamma correction (on cpu), sobel(on nvidia gpu). But, strangely the program is crashing frequently where the frequency lies anywhere between 4 hours to 14 hours. I've no clue how to debug this error as it gives only one error message in stack trace "Fatal Python Error". Packages/Libraries used: numba.cuda, numpy, sklearn.cluster, cv2, multiprocessing.Pool Any idea how to debug/resolve this python crash error. Please see the below stack trace of the error. ``` ======= Backtrace: ========= INFO:cuda_img_process:53760 /lib64/libc.so.6(+0x816b9)[0x7f7d483f96b9]

This looks like an issue due to numba or features related to numba. The traceback seems to be indicating that memory allocation failed. I'd suggest checking the GPU-memory utilization. Also, try to debug it with environment variable NUMBA_CUDA_MAX_PENDING_DEALLOCS_COUNT=0 to disable the deferring of deallocation (see http://numba.pydata.org/numba-doc/latest/cuda/memory.html?highlight=numba_cuda_max_pending_deallocs_count#deallocation-behavior for details).

If you have further problem with numba, I'd suggest opening a ticket at https://github.com/numba/numba/issues.

Also, it would be useful to know how the threads using the GPUs. Are all threads using the same GPU? Or, is each thread assigned to a GPU?

I've monitored the GPU memory utilization but it is not much. I'm having 4 GPUs of 32GB each on my machine and there is hardly 4 to 5 GBs of memory used & at max 15-20% use in terms of Volatile GPU Utilisation

Output of nvidia-smi below: image

Also, it would be useful to know how the threads using the GPUs. Are all threads using the same GPU? Or, is each thread assigned to a GPU?

I've different threads/processes running on all 4 different GPUs. Although the load is not ideally balanced among the 4 GPUs but it doesn't differ so much between 4 devices.

I'll try and test with equal load distribution among 4 GPUs as well & see if the problem gets resolved.
