# Googlenet Example
|
||||
|
||||
## Description
|
||||
|
||||
This example is for Googlenet model training and evaluation.
|
||||
|
||||
## Requirements
|
||||
|
||||
- Install [MindSpore](https://www.mindspore.cn/install/en).
|
||||
|
||||
- Download the CIFAR-10 binary version dataset.
|
||||
|
||||
> Unzip the CIFAR-10 dataset to any path you want and the folder structure should be as follows:
|
||||
> ```
|
||||
> .
|
||||
> ├── cifar-10-batches-bin # train dataset
|
||||
> └── cifar-10-verify-bin # infer dataset
|
||||
> ```
|
||||
|
||||
## Running the Example
|
||||
|
||||
### Training
|
||||
|
||||
```
|
||||
python train.py --data_path=your_data_path --device_id=6 > out.train.log 2>&1 &
|
||||
```
|
||||
The python command above will run in the background, you can view the results through the file `out.train.log`.
|
||||
|
||||
After training, you'll get some checkpoint files under the script folder by default.
|
||||
|
||||
You will get the loss value as following:
|
||||
```
|
||||
# grep "loss is " out.train.log
|
||||
epoch: 1 step: 390, loss is 1.4842823
|
||||
epcoh: 2 step: 390, loss is 1.0897788
|
||||
...
|
||||
```
|
||||
|
||||
### Evaluation
|
||||
|
||||
```
|
||||
python eval.py --data_path=your_data_path --device_id=6 --checkpoint_path=./train_googlenet_cifar10-125-390.ckpt > out.eval.log 2>&1 &
|
||||
```
|
||||
The above python command will run in the background, you can view the results through the file `out.eval.log`.
|
||||
|
||||
You will get the accuracy as following:
|
||||
```
|
||||
# grep "result: " out.eval.log
|
||||
result: {'acc': 0.934}
|
||||
```
|
||||
|
||||
### Distribute Training
|
||||
```
|
||||
sh run_distribute_train.sh rank_table.json your_data_path
|
||||
```
|
||||
The above shell script will run distribute training in the background, you can view the results through the file `train_parallel[X]/log`.
|
||||
|
||||
You will get the loss value as following:
|
||||
```
|
||||
# grep "result: " train_parallel*/log
|
||||
train_parallel0/log:epoch: 1 step: 48, loss is 1.4302931
|
||||
train_parallel0/log:epcoh: 2 step: 48, loss is 1.4023874
|
||||
...
|
||||
train_parallel1/log:epoch: 1 step: 48, loss is 1.3458025
|
||||
train_parallel1/log:epcoh: 2 step: 48, loss is 1.3729336
|
||||
...
|
||||
...
|
||||
```
|
||||

# [GoogleNet Description](#contents)
|
||||
|
||||
GoogleNet, a 22 layers deep network, was proposed in 2014 and won the first place in the ImageNet Large-Scale Visual Recognition Challenge 2014 (ILSVRC14). GoogleNet, also called Inception v1, has significant improvement over ZFNet (The winner in 2013) and AlexNet (The winner in 2012), and has relatively lower error rate compared to VGGNet. Typically deeper deep learning network means larger number of parameters, which makes it more prone to overfitting. Furthermore, the increased network size leads to increased use of computational resources. To tackle these issues, GoogleNet adopts 1*1 convolution middle of the network to reduce dimension, and thus further reduce the computation. Global average pooling is used at the end of the network, instead of using fully connected layers. Another technique, called inception module, is to have different sizes of convolutions for the same input and stacking all the outputs.

# [Model Architecture](#contents)
|
||||
|
||||
The overall network architecture of GoogleNet is shown below:
|
||||
|
||||
![](https://miro.medium.com/max/3780/1*ZFPOSAted10TPd3hBQU8iQ.png)
|
||||
|
||||
Specifically, the GoogleNet contains numerous inception modules, which are connected together to go deeper. In general, an inception module with dimensionality reduction consists of **1×1 conv**, **3×3 conv**, **5×5 conv**, and **3×3 max pooling**, which are done altogether for the previous input, and stack together again at output.

# [Features](#contents)
|
||||
|
||||
## Mixed Precision
|
||||
|
||||
The [mixed precision](https://www.mindspore.cn/tutorial/zh-CN/master/advanced_use/mixed_precision.html) training method accelerates the deep learning neural network training process by using both the single-precision and half-precision data formats, and maintains the network precision achieved by the single-precision training at the same time. Mixed precision training can accelerate the computation process, reduce memory usage, and enable a larger model or batch size to be trained on specific hardware.
|
||||
For FP16 operators, if the input data type is FP32, the backend of MindSpore will automatically handle it with reduced precision. Users could check the reduced-precision operators by enabling INFO log and then searching ‘reduce precision’.

## [Training Process](#contents)
|
||||
|
||||
### Training
|
||||
|
||||
```
|
||||
python train.py > train.log 2>&1 &
|
||||
```
|
||||
|
||||
The python command above will run in the background, you can view the results through the file `train.log`.
|
||||
|
||||
After training, you'll get some checkpoint files under the script folder by default. The loss value will be achieved as follows:
|
||||
|
||||
```
|
||||
# grep "loss is " train.log
|
||||
epoch: 1 step: 390, loss is 1.4842823
|
||||
epcoh: 2 step: 390, loss is 1.0897788
|
||||
...
|
||||
```
|
||||
|
||||
The model checkpoint will be saved in the current directory.
|
||||
|
||||
### Distributed Training
|
||||
|
||||
```
|
||||
sh scripts/run_train.sh rank_table.json
|
||||
```
|
||||
|
||||
The above shell script will run distribute training in the background. You can view the results through the file `train_parallel[X]/log`. The loss value will be achieved as follows:
|
||||
|
||||
```
|
||||
# grep "result: " train_parallel*/log
|
||||
train_parallel0/log:epoch: 1 step: 48, loss is 1.4302931
|
||||
train_parallel0/log:epcoh: 2 step: 48, loss is 1.4023874
|
||||
...
|
||||
train_parallel1/log:epoch: 1 step: 48, loss is 1.3458025
|
||||
train_parallel1/log:epcoh: 2 step: 48, loss is 1.3729336
|
||||
...
|
||||
...
|
||||
```
|
||||
|
||||
|
||||
## [Evaluation Process](#contents)
|
||||
|
||||
### Evaluation
|
||||
|
||||
Before running the command below, please check the checkpoint path used for evaluation. Please set the checkpoint path to be the absolute full path, e.g., "username/googlenet/train_googlenet_cifar10-125_390.ckpt".
|
||||
|
||||
```
|
||||
python eval.py > eval.log 2>&1 &
|
||||
OR
|
||||
sh scripts/run_eval.sh
|
||||
```
|
||||
|
||||
The above python command will run in the background. You can view the results through the file "eval.log". The accuracy of the test dataset will be as follows:
|
||||
|
||||
```
|
||||
# grep "accuracy: " eval.log
|
||||
accuracy: {'acc': 0.934}
|
||||
```
|
||||
|
||||
Note that for evaluation after distributed training, please set the checkpoint_path to be the last saved checkpoint file such as "username/googlenet/train_parallel0/train_googlenet_cifar10-125_48.ckpt". The accuracy of the test dataset will be as follows:
|
||||
|
||||
```
|
||||
# grep "accuracy: " dist.eval.log
|
||||
accuracy: {'acc': 0.9217}
|
||||
```

## [How to use](#contents)
|
||||
### Inference
|
||||
|
||||
If you need to use the trained model to perform inference on multiple hardware platforms, such as GPU, Ascend 910 or Ascend 310, you can refer to this [Link](https://www.mindspore.cn/tutorial/zh-CN/master/advanced_use/network_migration.html). Following the steps below, this is a simple example:
|
||||
|
||||
```
|
||||
# Load unseen dataset for inference
|
||||
dataset = dataset.create_dataset(cfg.data_path, 1, False)
|
||||
|
||||
# Define model
|
||||
net = GoogleNet(num_classes=cfg.num_classes)
|
||||
opt = Momentum(filter(lambda x: x.requires_grad, net.get_parameters()), 0.01,
|
||||
cfg.momentum, weight_decay=cfg.weight_decay)
|
||||
loss = nn.SoftmaxCrossEntropyWithLogits(sparse=True, reduction='mean',
|
||||
is_grad=False)
|
||||
model = Model(net, loss_fn=loss, optimizer=opt, metrics={'acc'})
|
||||
|
||||
# Load pre-trained model
|
||||
param_dict = load_checkpoint(cfg.checkpoint_path)
|
||||
load_param_into_net(net, param_dict)
|
||||
net.set_train(False)
|
||||
|
||||
# Make predictions on the unseen dataset
|
||||
acc = model.eval(dataset)
|
||||
print("accuracy: ", acc)
|
||||
```
|
||||
|
||||
### Continue Training on the Pretrained Model
|
||||
|
||||
```
|
||||
# Load dataset
|
||||
dataset = create_dataset(cfg.data_path, cfg.epoch_size)
|
||||
batch_num = dataset.get_dataset_size()
|
||||
|
||||
# Define model
|
||||
net = GoogleNet(num_classes=cfg.num_classes)
|
||||
# Continue training if set pre_trained to be True
|
||||
if cfg.pre_trained:
|
||||
param_dict = load_checkpoint(cfg.checkpoint_path)
|
||||
load_param_into_net(net, param_dict)
|
||||
lr = lr_steps(0, lr_max=cfg.lr_init, total_epochs=cfg.epoch_size,
|
||||
steps_per_epoch=batch_num)
|
||||
opt = Momentum(filter(lambda x: x.requires_grad, net.get_parameters()),
|
||||
Tensor(lr), cfg.momentum, weight_decay=cfg.weight_decay)
|
||||
loss = nn.SoftmaxCrossEntropyWithLogits(sparse=True, reduction='mean', is_grad=False)
|
||||
model = Model(net, loss_fn=loss, optimizer=opt, metrics={'acc'},
|
||||
amp_level="O2", keep_batchnorm_fp32=False, loss_scale_manager=None)
|
||||
|
||||
# Set callbacks
|
||||
config_ck = CheckpointConfig(save_checkpoint_steps=batch_num * 5,
|
||||
keep_checkpoint_max=cfg.keep_checkpoint_max)
|
||||
time_cb = TimeMonitor(data_size=batch_num)
|
||||
ckpoint_cb = ModelCheckpoint(prefix="train_googlenet_cifar10", directory="./",
|
||||
config=config_ck)
|
||||
loss_cb = LossMonitor()
|
||||
|
||||
# Start training
|
||||
model.train(cfg.epoch_size, dataset, callbacks=[time_cb, ckpoint_cb, loss_cb])
|
||||
print("train success")
|
||||
```
|
||||
|
||||
