Core dump Illegal Instruction on detectnet_v2 example

amertahir · October 28, 2019, 10:44pm

Hi,

I’m trying to run example detectnet_v2 and facing an Illegal Instruction error when I execute the tlt-train command. I’m running it on RTX 2080 GPU on a Dell R720 server. Here’s the output log:

root@2a9a93f3988b:/workspace# tlt-train detectnet_v2 -e $SPECS_DIR/detectnet_v2_train_resnet18_kitti.txt -r $USER_EXPERIMENT_DIR/experiment_dir_unpruned -k $KEY -n resnet18_detector
Using TensorFlow backend.

[[2548,1],0]: A high-performance Open MPI point-to-point messaging module
was unable to find any relevant network interfaces:

Module: OpenFabrics (openib)
Host: 2a9a93f3988b

Another transport will be used instead, although this may result in
lower performance.

NOTE: You can disable this warning by setting the MCA parameter
btl_base_warn_component_unused to 0.

I actually figured it out, I’m using an old CPU which doesn’t support BMI2 set of instructions. The culprit is SHLX instruction which was added as part of BMI2 in Haswell processors. Mine is Intel(R) Xeon(R) CPU E5-2643 which doesn’t support that instruction.

The SHLX instruction is found at:
0x00007f10743a7327 in _RasterizeBboxOp::Compute(tensorflow::OpKernelContext*) ()
from /usr/local/lib/python2.7/dist-packages/modulus/processors/…/lib/op_rasterize_bbox.so

Hi amertahir,
Thanks for the info. If there is latest result of tlt-train, please let me know.

amertahir · October 30, 2019, 7:09pm

Yes I’m using the latest version of the container: nvcr.io/nvidia/tlt-streamanalytics:v1.0_py2

Morganh · October 31, 2019, 2:28am

Hi amertahir,
If you are getting the error, possibly you are using an incompatible type of CPU that the TensorFlow package in TLT container does not supported. Please try to do training on other machines.

jefflgaol · March 3, 2020, 9:16am

Same thing happened with my Intel Xeon computer. So is there any solution for this? Or using another machine is the final solution?

Morganh · March 3, 2020, 4:24pm

For your computer, could you please try python -c ‘import tensorflow as tf’?

jefflgaol · March 10, 2020, 1:50am

It didn’t show anything actually. The illegal instruction only happened when I ran it inside jupyter. Maybe I’ll take a look at your link. Thank you.

Hi Morganh / all,

i have same issue, and it’s not because of tensorflow!
What i can do now?

Starting to train how explained in the docs:

!tlt-train detectnet_v2 -e $SPECS_DIR/detectnet_v2_train_resnet18_kitti_face.txt \
                    -r $USER_EXPERIMENT_DIR/experiment_dir_unpruned \
                    -k $KEY \
                    -n resnet18_detector


Using TensorFlow backend.

I too not really understand the error, why this happen? i used a suggested size for the training data 960x544:

target/truncation is not updated to match the crop areaif the dataset contains target/truncation.

Thanks for checking and let me know whats the problem here.

Dear Morganh,

tried again the detectnet_v2 training with kitti dataset, without changing config or something and get now following error? Why TLT is so buggy? You write on your website it’s working “out of the box”… i think this is not right and very frustrating.

Using TensorFlow backend.

Firstly, please ignore the warning

target/truncation is not updated to match the crop areaif the dataset contains target/truncation.

For your latest error, please delete the result folder and trigger training again.
What’s your cpu info?
For " Illegal instruction", see Illegal instruction too.

Hi Morganh,

i cleaned everything and start again the “default” kitti-dataset training and ended up again with illegal instruction error.

Using TensorFlow backend.

i will try later on a other PC, but is this error really because of my CPU and what i can do against it?

Morganh · June 15, 2020, 4:41pm

It may be related to missing some instruction of cpu.
See Core dumped on examples - #4 by nikki_dzhurov too.

Hi Morganh,

okay my CPU is missing AVX2, on other machine with AVX2 no errors happen.

Given a solution to use TLT on a CPU with only AVX? Or the only solution is to buy new CPU?

btw. for other, example how to check AVX2 SUPPORTED by CPU:

root@ai:~# grep avx /proc/cpuinfo

`flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc cpuid aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm pcid sse4_1 sse4_2 x2apic popcnt tsc_deadline_timer aes xsave **avx** lahf_lm epb pti ssbd ibrs ibpb stibp tpr_shadow vnmi flexpriority ept vpid xsaveopt dtherm ida arat pln pts md_clear flush_l1d`

if you dont get any results for:
root@ai:~# grep avx2 /proc/cpuinfo

Than your CPU not supporting AVX2

Morganh · June 15, 2020, 5:40pm

Suggest to use cpu which supports AVX2. The i7-2600 may be a little old.
