If you want to add other resource types, please modify def compute_resource(…​) in network_util python files (e.g. network_utils/network_utils_alexnet).

                                        -ir INIT_RESOURCE_REDUCTION, --init_resource_reduction INIT_RESOURCE_REDUCTION: For each iteration, target resource = current resource - init_resource_reduction*(resource_reduction_decay\*\*(iteration-1)).

                                        -st SHORT_TERM_FINE_TUNE_ITERATION, --short_term_fine_tune_iteration SHORT_TERM_FINE_TUNE_ITERATION: Short-term fine-tune iteration (default: 10).

                                        -lt LOOKUP_TABLE_PATH, --lookup_table_path LOOKUP_TABLE_PATH: Path to lookup table.

                                        Training AlexNet on CIFAR-10. Train from scratch: ```bash python train.py data/ --dir models/alexnet/no-pretrain/checkpoint.pth.tar --arch alexnet ``` Use Imagenet-pretrained model: ```bash python train.py data/ --dir models/alexnet/pretrain/checkpoint.pth.tar --pretrained --lr 0.01 --arch alexnet ``` Evaluation: ```bash python eval.py data/ --dir models/alexnet/no-pretrain/checkpoint.pth.tar --arch alexnet ``` ```bash python train.py data/ --dir models/mobilenet/model.pth.tar --arch mobilenet ``` 2. **Measuring Latency** Here we build the latency lookup table for `cuda:0` device: ```bash python build_lookup_table.py --dir latency_lut/lut_alexnet.pkl --arch alexnet ``` It measures latency of different layers contained in the network (i.e. **AlexNet** here). For conv layers, the sampled numbers of feature channels are multiples of `MIN_CONV_FEATURE_SIZE`. For fc layers, the sampled numbers of features are multiples of `MIN_FC_FEATURE_SIZE`.

                                        Applying NetAdapt Modify which GPUs will be utilized (`-gp`) in `netadapt_alexnet.sh` and run the script to apply NetAdapt to a pretrained model: ```bash sh netadapt_alexnet.sh ``` After obtaining the adapted model, we need to finetune the model: ```bash python train.py data/ --arch alexnet --resume models/alexnet/no-pretrain/prune-by-mac/iter_100_best_model.pth.tar --dir models/alexnet/no-pretrain/checkpoint-adapt.pth.tar ``` <p align="center"> <img src="fig/netadapt_algo.png" alt="photo not available" width="90%" height="90%"> </p>

                                        Evaluation Using Adapted Models After applying NetAdapt to a pretrained model, we can evaluate this adapted model using: ```bash python eval.py data/ --dir models/alexnet/no-pretrain/checkpoint-adapt.pth.tar --arch alexnet ``` The adapted model can be restored **without modifying the orignal python file**.

                                        Create your own network_utils python file (said network_utils_yourNetworkOrTask.py) and place it under network_utils.

                                        Implement functions described in [network_utils_abstract.py](network_utils/network_utils_abstract.py).

                                        As we provide an example of applying NetAdapt to AlexNet, you can also build your network_utils based on [network_utils_alexnet.py](network_utils/network_utils_alexnet.py): ```bash cd network_utils cp network_utils_alexnet.py ./network_utils_yourNetworkOrTask.py ```

                                        Add from .network_utils_yourNetworkOrTask import * to init.py, which is under [the same directory](network_utils/init.py).

                                        Modify class networkUtils_alexnet(…​) in [line 44](network_utils/network_utils_alexnet.py#L44) in network_utils_yourNetworkOrTask.py to class networkUtils_yourNetworkOrTask(…​).

                                        Modify def alexnet(…​) in [line 325-326](network_utils/network_utils_alexnet.py#L325-L326) to: bash def yourNetworkOrTask(model, input_data_shape, dataset_path, finetune_lr=1e-3): return networkUtils_yourNetworkOrTask(model, input_data_shape, dataset_path, finetune_lr)

                                        Specify training/validation data loader, loss functions, optimizers, network architecture, training method, and evaluation method in network_utils_yourNetworkOrTask.py if there is any difference from the AlexNet example: Modify data loader and loss functionsin function def init(…​): in [line 52](network_utils/network_utils_alexnet.py#L52-L125). Specify additive skip connections if there is any and modify def simplify_network_def_based_on_constraint(…​) in network_utils_yourNetworkOrTask.py. You can see how our implementation uses additive skip connections [here](functions.py#L543-L549). Modify training method (short-term finetune) in function def fine_tune(…​): in [line 245](network_utils/network_utils_alexnet.py#L245-L288). Modify evaluation method in function def evaluate(…​): in [line 291](network_utils/network_utils_alexnet.py#L291-L322). You can see how these methods are utilized by the framework [here](worker.py#L39-L62).

                                        Our current code base supports pruning Conv2d, ConvTranspose2d, and Linear with additive skip connection. If your network architecture is not supported, please modify [this](network_utils/network_utils_alexnet.py#L142-L199). If you want to use other metrics (resource type) to prune networks, please modify [this](network_utils/network_utils_alexnet.py#L234-L238).

                                        We can apply NetAdapt to different networks or tasks by using --arch yourNetworkOrTask in scripts/netadapt_alexnet-0.5mac.sh. As for the values of other arguments, please see [Usage](#usage). Generally, if you want to apply NetAdapt to a different task, you might change input_data_shape. If your network architecture is very different from that of MobileNet, you would have to modify the values of --init_resource_reduction_ratio and --resource_reduction_decay to get a different resource reduction schedule.

                                        Get lowest mac address

                                        Asked 2022-Apr-08 at 01:42

                                        What is the best way to get the network adapter with the lowest mac address? There are multiple network adapters named Intel(R) I210, just need the one with the lowest mac address.

                                        $adapters = Get-NetAdapter -InterfaceDescription "Intel(R) I210*"
                                        
                                        foreach ($adapter in $adapters) {
                                            Write-Host $adapter.MacAddress
                                            $lastMacSegment = $adapter.MacAddress.Split("-")[-1]
                                            Write-Host "Last segment $lastMacSegment"
                                            $dec = [Convert]::ToInt64($lastMacSegment, 16)
                                            Write-Host $dec
                                        }
                                        
                                        ???

                                        You can use Sort-Object to sort the output from Get-NetAdapter based on the .MacAddress property and then get the lowest Mac Address based on that sort.

                                        Get-NetAdapter "Intel(R) I210*" | Sort-Object MacAddress
                                        

                                        For the lowest you would simply pipe it to Select-Object -First 1.

                                        I was previously using Sort-Object { [PhysicalAddress] $_.MacAddress } however this is not even needed as Lee_Dailey pointed out.
