    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 9. Creating system variable) by specifying in the Variable value field the path to the cache location with an arbitrary folder name. For example, D:\IX_GPU_cache. The specified directory will store the cache for all used detection tools and neural networks.

  3. To call the utility, open in the command line: C:\Program Files\Common Files\AxxonSoft\DetectorPack\VTGpuCacheGenerator.exe and press Enter.

As a result, the process of creating cache starts, which will take takes about 30 minutes. The duration of the process depends on the selected types of cache, number of countries and NVIDIA Nvidia GPU model.

Optimizing the operation of the License Plate Recognition VT on GPU is complete.

Note
titleAttention!

Cache must be recreated:

  • if you update the VT LPR add-on (see Installing DetectorPack add-ons),
  • if you change the NVIDIA Nvidia GPU model,
  • if you update NVIDIA update Nvidia GPU drivers.
