General information

It can take several minutes to launch neural analytics algorithms on NVIDIA GPU after Server restart. MeanwhileAt this time, the neural models are optimized for the current GPU type.

...

Starting with DetectorPack 3.9, a utility was added to the Neuro Pack add-ons (see Installing DetectorPack add-ons), which allows you to create GPU neural network caches without using Axxon One. The presence of the cache speeds up the initialization and optimizes video memory consumption.

Optimizing the operation of neural analytics on GPU

To optimize the operation of the neural analytics on GPU, do the following:

1. Stop the Server (see Shutting down a Server).
   

   Note
   title Attention!
   If the system has the software running on GPU, it is necessary to stop its operation.

2. Create the GPU_CACHE_DIR system variable (see Appendix 10. Creating system variable) by specifying in the Variable value field the path to the cache location with an arbitrary folder name. For example, D:\GPU_cache. The specified directory will store the cache for all used detection tools and neural networks.
   The cache size depends on the number of neural networks used and their type, the . The minimum size is 70 MB.
   

3. Note

   title	Attention!

   This function works in beta mode for all detection tools that use neural analytics (see General information on Neural Analytics), except Face detection. To optimize Face detection operation using the GPU_CACHE_DIR system variable, you need to perform additional actions (see Optimizing the operation of Face detection on GPU). Run the command prompt as administrator.

4. To call the utility, open in the command line: prompt, enter C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroPackGpuCacheGenerator.exe and press .

5. Press Enter.

6. Specify the ID of the required GPU (see General Information on Configuring DetectionSelecting Nvidia GPU when configuring detection tools).
7. Press) and press Enter.

Optimizing the operation of the neural analytics on GPU is complete. The utility will create the caches of four neural networks included in the Neuro Pack add-ons:

• GeneralNMHuman_v1.0GPU_onnx.ann—human;
• smokeScanned_v1_onnx.ann—smoke detection;
• fireScanned_v1_onnx.ann—fire detection;
• reid_15_0_256__osnetfpn_segmentation_noise_20_common_29_onnx.ann—search for the similar in the Neural Tracker neurotracker (see Image search).
  
  

Creating GPU neural network caches using parameters

...

1. -p is a parameter to create a cache for a particular neural network.
   Command example:
   

   Code Block
   C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroPackGpuCacheGenerator.exe -p "<System disk>\<Neural network location directory>\Neural_network_name.ann"

   To create a cache for multiple neural networks, list the paths to the selected neural networks, separated by a space.
   Command example:

   Code Block
   C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroPackGpuCacheGenerator.exe -p "<System disk>\<Neural network location directory>\Neural_network_name.ann" "C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroSDK\WaterLevelRuleNet_origin_onnx.ann"

   
   

2. -v is a parameter to output the procedure log to the console during cache generation.
   Command example to automatically create caches of four neural networks included in the Neuro Pack add-ons with log output:
   

   Code Block
   C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroPackGpuCacheGenerator.exe -v

   Command example:
   

   Code Block
   C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroPackGpuCacheGenerator.exe -p "<System disk>\<Neural network location directory>\Neural_network_name.ann" -v

   
   

3. --int8=1 is a parameter to create a quantized version of the cache for those neural networks for which quantization is available. By default, the --int8=0 parameter is disabled.
   Command example:
   

   Attention!

   Code Block
   C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroPackGpuCacheGenerator.exe --int8=1
   Note
   title

   The neural networks for which the quantization mode is available

   are included in the Neuro Pack add-ons together with the *.info file.

   The neural networks for which the quantization mode is available (see Configuring (see Neurotracker):

   • GeneralNMCar_v1.0GPU_onnx.ann—vehicles.
   • GeneralNMHuman_v1.0GPU_onnx.ann—human.
   • GeneralNMHumanTopView_v0.8GPU_onnx.ann—human, top view.
