Introduction

MindWizard is a tool for quickly generating classic network scripts. It collects user preference on the combination of network parameters, such models, hyperparameters and datasets, then automatically generates target network scripts. The generated scripts can be used for training and evaluation in the Ascend or GPU environment.

Installation

This tool is part of MindInsight and accessible to users after installing MindInsight, no extra installation is needed.

Commandline Usage

mindwizard [-h] [--version] name
positional arguments:
  name        Specify the new project name.
optional arguments:
  -h, --help  show this help message and exit
  --version   show program's version number and exit

Generating Network Project

Run the mindwizard command and answer the following questions as prompted：

1. Select a network（LeNet / AlexNet / ResNet50 / ...）

   1.1. Select a Loss Function（SoftmaxCrossEntropyExpand / SoftmaxCrossEntropyWithLogits / ...）

   1.2. Select a Optimizer（Adam / Momentum / SGD ...）

2. Select a Dataset（MNIST / Cifar10 / ImageNet / ...）

After the project is generated, user can perform training and evaluation. For details, see README in the network project.

Example

Generate LeNet project.

$ mindwizard project

>>> Please select a network:
   1: alexnet
   2: lenet
   3: resnet50
 : 2
>>> Please select a loss function:
   1: SoftmaxCrossEntropyExpand
   2: SoftmaxCrossEntropyWithLogits
 [2]: 2
>>> Please select an optimizer:
   1: Adam
   2: Momentum
   3: SGD
 [2]: 2
>>> Please select a dataset:
   1: MNIST
 [1]: 1

lenet is generated in $PWD/project

$ cd $PWD/project/scripts
