# Example configuration files

Example configuration files (for use with model\_configurator) are included in
the `SampleConfigurations` sub-directory.

The file `config_8cores_only_smallset.csv` can be used with the
model\_configurator for an 8-core AIC100 SoC to do a shallow search of
parameters values. This configuration file restricts the search space to
combinations that satisfy the following conditions: cores\*instances = 8,
batchsize=1 or 4, mos=1,4, or 8, ols=1,2, or 4. It has 36 parameter
combinations and may be helpful to quickly gauge the parameters to which
a specified network is sensitive and hence worth exploring with a deeper
search.

The file `config_8cores_only.csv` is also suited for use with an
8-core AIC100 SoC; however, it specifies a deeper search over the same
parameters as `config_8cores_only_smallset.csv`. It also targets
configurations that satisfy the criterion cores\*instances = 8; however,
it sweeps a larger range of values for the other parameters.
Specifically, `batchsize=1,2,4,` or `8`, `mos=1,2,4,` or `8`, and `ols = 1,2,` or
`4`. The file has 104 combinations and hence model\_configurator will take
a longer time to finish.

It’s recommended that model\_configurator be invoked with one of the
above configuration files for new networks to determine if there is an
opportunity to tune parameters further. The default parameter values may
not always be optimal.

The file `config_14cores_ref.csv` is provided as a reference that
contains all valid combinations of cores and instances for a 14-core
AIC100 SoC. It sweeps over batchsize=1,2,4,8, or 14, mos=1,2,4, 8, or 14
and ols=1,2, or 4. It has 304 combinations, including some that use
fewer than 14 cores for the combination of cores and instances. The
following command is one example that can generate this configuration
file:

$ python3 /opt/qti-aic/scripts/qaic-model-configurator/model_configurator.py vgg16.onnx onnx -list-configs -save-configs ./config_14cores_ref.csv -iter 500 -cores=1,2,4,8,14 -instances 1,2,4,8,14 -batchsize 1,2,4,8,14 -mos 1,2,4,8,14 -ols 1,2,4

By filtering out just the combinations of interest, other configuration files
can be derived from this reference file. For example,
`config_8cores_only_smallset.csv` can be derived from
`config_14cores_ref.csv` by selecting only combinations for which
cores\*instances=8, batchsize=1 or 4, mos=1,4, or 8, ols=1,2, or 4.

The selected configuration file can be passed to `qaic-model-configurator` to
run a search using the `-load-configs` option. For example:

$ python3 /opt/qti-aic/scripts/qaic-model-configurator/model_configurator.py vgg16.onnx onnx -output-dir int8host -list-configs -load-configs ./config_14cores_ref.csv -iter=500 -quantization-schema-activations=symmetric_with_uint8 -quantization-precision=Int8 -input-list-generate -image-dir ./ -height 640 -width 640 -image-type jpg -reuse-single-file
    Copy to clipboard

**Note:** Options that impact how a model should be executed, such as
quantization and format conversion options should be added to a
`qaic-model-configurator` invocation that performs the actual
measurements, such as the one above.
