使用MNIST数据集进行联邦学习,MNIST是手写数字识别的数据集。从kaggle下载csv格式的数据集。
FATE训练时需要数据集有id,MNIST数据集里有6w条数据,模拟横向联邦学习。
把数据集分为两个各有3w条记录的数据集。
#第一行最前面加上id,第二行开始加序号,并用逗号作为分隔符。
awk -F'\t' -v OFS=',' '
NR == 1 {print "id",$0; next}
{print (NR-1),$0}' mnist_train.csv > mnist_train_with_id.csv
#将表头的label替换成y,在FATE里label的名字通常为y。
sed -i "s/label/y/g" mnist_train_with_id.csv
#将mnist_train_with_id.csv分割,每一个文件有30001行(一行标题和30000行数据)。会生成两个文件:mnist_train_3w.csvaa和mnist_train_3w.csvab。将两个文件重命名
split -l 30001 mnist_train_with_id.csv mnist_train_3w.csv
mv mnist_train_3w.csvaa mnist_train_3w_a.csv
mv mnist_train_3w.csvab mnist_train_3w_b.csv
sed -i "`cat -n mnist_train_3w_a.csv |head -n 1`" mnist_train_3w_b.csv
将两个文件(a、b)拷贝到两台机器的对应目录里:
/data/projects/fate/confs-
/shared_dir/examples/data
注:
需要替换成自己节点的party id。
#以机器A示例,拷贝文件的命令
cp mnist_train_3w_a.csv /data/projects/fate/confs-10001/shared_dir/examples/data/
可能用到的:
#将文件拷贝到另一台机器的桌面上
scp mnist_train_3w_b.csv [email protected]:/home/xxx/Desktop
进入目录
/data/projects/fate/confs-
/shared_dir/examples/dsl/v2/homo_nn
注:
新建upload_data_host.json
:
{
"file": "examples/data/mnist_train_3w_a.csv",
"head": 1,
"partition": 10,
"work_mode": 1,
"table_name": "homo_mnist_host",
"namespace": "homo_mnist_host"
}
docker exec -it confs-<partyID>_python_1 bash
python fate_flow/fate_flow_client.py -f upload -c /data/projects/fate/examples/dsl/v2/homo_nn/upload_data_host.json

注意file,table_name和namespace的变化
import keras
from keras.models import Sequential
from keras.layers import Dense, Dropout, Flatten
model = Sequential()
model.add(Dense(512,activation='relu',input_shape=(784,)))
model.add(Dense(256,activation='relu'))
model.add(Dense(10,activation='softmax'))
//得到json格式的模型:
json = model.to_json()
print(json)
注:进入python容器之后,没安装tensorflow和keras的话需要进行安装(如:pip install tensorflow),之后输入python,进入python解释器,直接敲上面的代码即可。
获取到模型的json格式,一会要用到
{"class_name": "Sequential", "config": {"name": "sequential", "layers": [{"class_name": "InputLayer", "config": {"batch_input_shape": [null, 784], "dtype": "float32", "sparse": false, "ragged": false, "name": "dense_input"}}, {"class_name": "Dense", "config": {"name": "dense", "trainable": true, "batch_input_shape": [null, 784], "dtype": "float32", "units": 512, "activation": "relu", "use_bias": true, "kernel_initializer": {"class_name": "GlorotUniform", "config": {"seed": null}}, "bias_initializer": {"class_name": "Zeros", "config": {}}, "kernel_regularizer": null, "bias_regularizer": null, "activity_regularizer": null, "kernel_constraint": null, "bias_constraint": null}}, {"class_name": "Dense", "config": {"name": "dense_1", "trainable": true, "dtype": "float32", "units": 256, "activation": "relu", "use_bias": true, "kernel_initializer": {"class_name": "GlorotUniform", "config": {"seed": null}}, "bias_initializer": {"class_name": "Zeros", "config": {}}, "kernel_regularizer": null, "bias_regularizer": null, "activity_regularizer": null, "kernel_constraint": null, "bias_constraint": null}}, {"class_name": "Dense", "config": {"name": "dense_2", "trainable": true, "dtype": "float32", "units": 10, "activation": "softmax", "use_bias": true, "kernel_initializer": {"class_name": "GlorotUniform", "config": {"seed": null}}, "bias_initializer": {"class_name": "Zeros", "config": {}}, "kernel_regularizer": null, "bias_regularizer": null, "activity_regularizer": null, "kernel_constraint": null, "bias_constraint": null}}]}, "keras_version": "2.4.0", "backend": "tensorflow"}
为了让任务模型的构建更加灵活,目前 FATE 使用了一套自定的领域特定语言 (DSL) 来描述任务。在 DSL 中,各种模块(例如数据读写 data_io,特征工程 feature-engineering, 回归 regression,分类 classification)可以通向一个有向无环图 (DAG) 组织起来。通过各种方式,用户可以根据自身的需要,灵活地组合各种算法模块。

说一下要改的和要注意的地方:
initiator,任务发起方,根据自己情况更改
role,角色定义部分,要根据自己部署的party id修改
job_parameters.common.work_mode 0表示单机版,1表示集群版
component_parameters.common.homo_nn_0下面增加"encode_label":true,
,表示使用独热编码,否则一会训练时会发生错误
component_parameters.common.homo_nn_0.nn_define 把刚才模型的json格式放上
component_parameters.role里面guest 和host的name
和namespace
根据上传数据时所定义的名字进行修改,这里按照我之前上传的配置json进行对应修改。
将新建(或修改后)的m_dsl.json
和m_conf.json
文件保存后,进行任务的提交,进入python容器(命令行显示(app-root) bash-4.2# )后,输入下面命令提交任务:
python fate_flow/fate_flow_client.py -f submit_job -c /data/projects/fate/examples/dsl/v2/homo_nn/m_conf.json -d /data/projects/fate/examples/dsl/v2/homo_nn/m_dsl.json
job提交成功截图:
提交后可以在fate board(http://机器IP地址:8080/)可视化的查看任务进度,点击红框标注位置可以看到任务更为详细的信息
进入python容器:
docker exec -it confs-<partyID>_python_1 bash
由于要使用flow命令行来进行模型部署,如果没安装的话,先安装一下fate client
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple/ fate_client
flow初始化
flow init --ip 192.168.xxx.xxx --port 9380
可以使用示例文件test_homo_dnn_multi_layer_predict_dsl.json
,我新建了p_dsl.json
{
"components": {
"dataio_0": {
"input": {
"data": {
"data": [
"reader_0.data"
]
},
"model": [
"pipeline.dataio_0.model"
]
},
"module": "DataIO",
"output": {
"data": [
"data"
]
}
},
"homo_nn_0": {
"input": {
"data": {
"test_data": [
"dataio_0.data"
]
},
"model": [
"pipeline.homo_nn_0.model"
]
},
"module": "HomoNN",
"output": {
"data": [
"data"
]
}
},
"reader_0": {
"module": "Reader",
"output": {
"data": [
"data"
]
}
}
}
}
根据上一次训练的model version
和model id
部署模型,指定新建好的p_dsl.json
文件
flow model deploy --model-id arbiter-10001#guest-10002#host-10001#model --model-version 2021041508244661802531 --dsl-path /data/projects/fate/examples/dsl/v2/homo_nn/p_dsl.json
部署完成截图:
可以参考示例文件test_homo_dnn_multi_layer_predict_conf.json
,我新建了文件p_conf.json
{
"dsl_version": 2,
"initiator": {
"role": "guest",
"party_id": 10002
},
"role": {
"arbiter": [
10001
],
"host": [
10001

"guest": [
10002

},
"job_parameters": {
"common": {
"work_mode": 1,

"job_type": "predict",
"model_id": "arbiter-10001#guest-10002#host-10001#model",

"component_parameters": {
"role": {

"namespace": "homo_mnist_test"
}
}
}
},
"host": {
"0": {
"reader_0": {
"table": {
"name": "homo_mnist_test",
"namespace": "homo_mnist_test"
}
}
}
}
}
}
}
注:
job_parameters.model_id和model_version要根据自己的模型修改,注意是部署之后输出信息中的对应信息!!
component_parameters下host和guest的table name
和namespace
要注意修改,下面给出我的test数据集准备过程:
类似于之前的上传数据,新建upload_data_test.json
,并处理数据集
awk -F'\t' -v OFS=',' '
NR == 1 {print "id",$0; next}
{print (NR-1),$0}' mnist_test.csv > mnist_test_with_id.csv
sed -i "s/label/y/g" mnist_test_with_id.csv
拷贝到这个路径下,然后上传数据
/data/projects/fate/confs-
/shared_dir/examples/data
新建upload_data_test.json
{
"file": "examples/data/mnist_test_with_id.csv",
"head": 1,
"partition": 10,
"work_mode": 1,
"table_name": "homo_mnist_test",
"namespace": "homo_mnist_test"
}
注意file,table_name和namespace的变化
保存文件后上传数据,首先进入host的python容器:
docker exec -it confs-<partyID>_python_1 bash
进入容器后,上传数据
python fate_flow/fate_flow_client.py -f upload -c /data/projects/fate/examples/dsl/v2/homo_nn/upload_data_test.json
注:我在host和guest双方都进行了数据上传工作,貌似不需要这样,host方上传即可
guest方发起模型预测任务
python fate_flow/fate_flow_client.py -f submit_job -c /data/projects/fate/examples/dsl/v2/homo_nn/p_conf.json -d /data/projects/fate/examples/dsl/v2/homo_nn/p_dsl.json
可以在fate board观察到 job 的进度
点击view this job 可以看到更详细的信息
点击模块后,再点击view the outputs
可以看到更加详细的模块输入输出状况
