Hi,

Do you use the _ssd\_mobilenet\_v2\_fpnlite\_320x320\_coco17\_tpu-8_ model from TensorFlow model zoo?  
Or a customized version?

We have tested the model and it can work correctly with the above instructions.  
If the default version is used, would you mind trying it again with some swap memory?

> Hi, Would you mind to create some swap space to see if help? You will need an extra space for the swap file. Ex. sudo fallocate -l 8G [/media/mySSD/swapfile] sudo chmod 600 [/media/mySSD/swapfile] sudo mkswap [/media/mySSD/swapfile] sudo /bin/sh -c 'echo "[/media/mySSD/swapfile] \t none \t swap \t defaults \t 0 \t 0" \>\> /etc/fstab' sudo swapon -a Thanks.

Thanks.
