下载笔记本在本基于笔记本的教程中，我们将创建和运行 TFX 管道以验证输入数据并创建 ML 模型。本笔记本基于我们在 简单 TFX 管道教程 中构建的 TFX 管道。如果您尚未阅读该教程，请在继续本笔记本之前阅读它。
任何数据科学或 ML 项目中的第一个任务是了解和清理数据，其中包括
- 了解每个特征的数据类型、分布和其他信息（例如，平均值或唯一值数量）
- 生成描述数据的初步模式
- 根据给定的模式识别数据中的异常值和缺失值
在本教程中，我们将创建两个 TFX 管道。
首先，我们将创建一个管道来分析数据集并生成给定数据集的初步模式。此管道将包括两个新组件，StatisticsGen 和 SchemaGen。
获得适当的数据模式后，我们将创建一个管道来训练基于先前教程中管道创建的 ML 分类模型。在此管道中，我们将使用第一个管道中的模式和一个新组件 ExampleValidator 来验证输入数据。
三个新组件 StatisticsGen、SchemaGen 和 ExampleValidator 是用于数据分析和验证的 TFX 组件，它们使用 TensorFlow 数据验证 库实现。
请参阅 了解 TFX 管道，以详细了解 TFX 中的各种概念。
设置
首先，我们需要安装 TFX Python 包并下载我们将用于模型的数据集。
升级 Pip
为了避免在本地运行时升级系统中的 Pip，请检查我们是否在 Colab 中运行。本地系统当然可以单独升级。
try:
import colab
!pip install --upgrade pip
except:
pass
安装 TFX
pip install -U tfx
您是否重新启动了运行时？
如果您使用的是 Google Colab，则第一次运行上面的单元格时，必须通过点击上面的“重新启动运行时”按钮或使用“运行时 > 重新启动运行时...”菜单来重新启动运行时。这是因为 Colab 加载包的方式。
检查 TensorFlow 和 TFX 版本。
import tensorflow as tf
print('TensorFlow version: {}'.format(tf.__version__))
from tfx import v1 as tfx
print('TFX version: {}'.format(tfx.__version__))

设置变量
有一些变量用于定义管道。您可以根据需要自定义这些变量。默认情况下，管道的所有输出都将在当前目录下生成。
import os
# We will create two pipelines. One for schema generation and one for training.
SCHEMA_PIPELINE_NAME = "penguin-tfdv-schema"
PIPELINE_NAME = "penguin-tfdv"
# Output directory to store artifacts generated from the pipeline.
SCHEMA_PIPELINE_ROOT = os.path.join('pipelines', SCHEMA_PIPELINE_NAME)
PIPELINE_ROOT = os.path.join('pipelines', PIPELINE_NAME)
# Path to a SQLite DB file to use as an MLMD storage.
SCHEMA_METADATA_PATH = os.path.join('metadata', SCHEMA_PIPELINE_NAME,
'metadata.db')
METADATA_PATH = os.path.join('metadata', PIPELINE_NAME, 'metadata.db')
# Output directory where created models from the pipeline will be exported.
SERVING_MODEL_DIR = os.path.join('serving_model', PIPELINE_NAME)
from absl import logging
logging.set_verbosity(logging.INFO) # Set default logging level.
准备示例数据
我们将下载示例数据集以用于我们的 TFX 管道。我们使用的数据集是 Palmer Penguins 数据集，它也用于其他 TFX 示例。
此数据集中有四个数值特征
- culmen_length_mm
- culmen_depth_mm
- flipper_length_mm
- body_mass_g
所有特征都已归一化到 [0,1] 范围内。我们将构建一个分类模型，用于预测企鹅的 species。
由于 TFX ExampleGen 组件从目录读取输入，因此我们需要创建一个目录并将数据集复制到其中。
import urllib.request
import tempfile
DATA_ROOT = tempfile.mkdtemp(prefix='tfx-data') # Create a temporary directory.
_data_url = 'https://raw.githubusercontent.com/tensorflow/tfx/master/tfx/examples/penguin/data/labelled/penguins_processed.csv'
_data_filepath = os.path.join(DATA_ROOT, "data.csv")
urllib.request.urlretrieve(_data_url, _data_filepath)
('/tmpfs/tmp/tfx-dataj_6ovg52/data.csv',
<http.client.HTTPMessage at 0x7ff39cac30a0>)
快速查看 CSV 文件。
head {_data_filepath}
species,culmen_length_mm,culmen_depth_mm,flipper_length_mm,body_mass_g 0,0.2545454545454545,0.6666666666666666,0.15254237288135594,0.2916666666666667 0,0.26909090909090905,0.5119047619047618,0.23728813559322035,0.3055555555555556 0,0.29818181818181805,0.5833333333333334,0.3898305084745763,0.1527777777777778 0,0.16727272727272732,0.7380952380952381,0.3559322033898305,0.20833333333333334 0,0.26181818181818167,0.892857142857143,0.3050847457627119,0.2638888888888889 0,0.24727272727272717,0.5595238095238096,0.15254237288135594,0.2569444444444444 0,0.25818181818181823,0.773809523809524,0.3898305084745763,0.5486111111111112 0,0.32727272727272727,0.5357142857142859,0.1694915254237288,0.1388888888888889 0,0.23636363636363636,0.9642857142857142,0.3220338983050847,0.3055555555555556
您应该能够看到五个特征列。 species 是 0、1 或 2 之一，所有其他特征的值应在 0 到 1 之间。我们将创建一个 TFX 管道来分析此数据集。
生成初步模式
TFX 管道使用 Python API 定义。我们将创建一个管道，从输入示例自动生成模式。此模式可以由人工审查并根据需要进行调整。模式最终确定后，可用于后续任务中的训练和示例验证。
除了 简单 TFX 管道教程 中使用的 CsvExampleGen 外，我们还将使用 StatisticsGen 和 SchemaGen
- StatisticsGen 计算数据集的统计信息。
- SchemaGen 检查统计信息并创建初始数据模式。
请参阅每个组件的指南或 TFX 组件教程，以详细了解这些组件。
编写管道定义
我们定义一个函数来创建 TFX 管道。一个 Pipeline 对象表示一个 TFX 管道，可以使用 TFX 支持的管道编排系统之一运行。
def _create_schema_pipeline(pipeline_name: str,
pipeline_root: str,
data_root: str,
metadata_path: str) -> tfx.dsl.Pipeline:
"""Creates a pipeline for schema generation."""
# Brings data into the pipeline.
example_gen = tfx.components.CsvExampleGen(input_base=data_root)
# NEW: Computes statistics over data for visualization and schema generation.
statistics_gen = tfx.components.StatisticsGen(
examples=example_gen.outputs['examples'])
# NEW: Generates schema based on the generated statistics.
schema_gen = tfx.components.SchemaGen(
statistics=statistics_gen.outputs['statistics'], infer_feature_shape=True)
components = [
example_gen,
statistics_gen,
schema_gen,
]
return tfx.dsl.Pipeline(
pipeline_name=pipeline_name,
pipeline_root=pipeline_root,
metadata_connection_config=tfx.orchestration.metadata
.sqlite_metadata_connection_config(metadata_path),
components=components)
运行管道
我们将像之前的教程一样使用 LocalDagRunner。
tfx.orchestration.LocalDagRunner().run(
_create_schema_pipeline(
pipeline_name=SCHEMA_PIPELINE_NAME,
pipeline_root=SCHEMA_PIPELINE_ROOT,
data_root=DATA_ROOT,
metadata_path=SCHEMA_METADATA_PATH))

INFO:absl:MetadataStore with DB connection initialized
INFO:absl:Component SchemaGen is finished.
如果管道成功完成，您应该看到“INFO:absl:Component SchemaGen is finished.”。
我们将检查管道的输出，以了解我们的数据集。
查看管道的输出
如之前的教程中所述，TFX 管道会生成两种输出，即工件和 元数据数据库 (MLMD)，其中包含工件和管道执行的元数据。我们在上面的单元格中定义了这些输出的位置。默认情况下，工件存储在 pipelines 目录下，元数据存储为 metadata 目录下的 sqlite 数据库。
您可以使用 MLMD API 以编程方式定位这些输出。首先，我们将定义一些实用程序函数来搜索刚刚生成的输出工件。
from ml_metadata.proto import metadata_store_pb2
# Non-public APIs, just for showcase.
from tfx.orchestration.portable.mlmd import execution_lib
# TODO(b/171447278): Move these functions into the TFX library.
def get_latest_artifacts(metadata, pipeline_name, component_id):
"""Output artifacts of the latest run of the component."""
context = metadata.store.get_context_by_type_and_name(
'node', f'{pipeline_name}.{component_id}')
executions = metadata.store.get_executions_by_context(context.id)
latest_execution = max(executions,
key=lambda e:e.last_update_time_since_epoch)
return execution_lib.get_output_artifacts(metadata, latest_execution.id)
# Non-public APIs, just for showcase.
from tfx.orchestration.experimental.interactive import visualizations
def visualize_artifacts(artifacts):
"""Visualizes artifacts using standard visualization modules."""
for artifact in artifacts:
visualization = visualizations.get_registry().get_visualization(
artifact.type_name)
if visualization:
visualization.display(artifact)
from tfx.orchestration.experimental.interactive import standard_visualizations
standard_visualizations.register_standard_visualizations()
现在我们可以检查管道执行的输出。
# Non-public APIs, just for showcase.
from tfx.orchestration.metadata import Metadata
from tfx.types import standard_component_specs
metadata_connection_config = tfx.orchestration.metadata.sqlite_metadata_connection_config(
SCHEMA_METADATA_PATH)
with Metadata(metadata_connection_config) as metadata_handler:
# Find output artifacts from MLMD.
stat_gen_output = get_latest_artifacts(metadata_handler, SCHEMA_PIPELINE_NAME,
'StatisticsGen')
stats_artifacts = stat_gen_output[standard_component_specs.STATISTICS_KEY]
schema_gen_output = get_latest_artifacts(metadata_handler,
SCHEMA_PIPELINE_NAME, 'SchemaGen')
schema_artifacts = schema_gen_output[standard_component_specs.SCHEMA_KEY]
INFO:absl:MetadataStore with DB connection initialized
现在该检查每个组件的输出。如上所述，Tensorflow 数据验证 (TFDV) 用于 StatisticsGen 和 SchemaGen，TFDV 还提供这些组件输出的可视化。
在本教程中，我们将使用 TFX 中的辅助可视化方法（在内部使用 TFDV）来显示可视化。
检查 StatisticsGen 的输出
# docs-infra: no-execute
visualize_artifacts(stats_artifacts)
您可以看到输入数据的各种统计信息。这些统计信息被提供给 SchemaGen，以自动构建数据的初始模式。
检查 SchemaGen 的输出
visualize_artifacts(schema_artifacts)
此模式是根据 StatisticsGen 的输出自动推断的。您应该能够看到 4 个 FLOAT 特征和 1 个 INT 特征。
导出模式以供将来使用
我们需要审查和细化生成的模式。审查后的模式需要持久化，以便在后续管道中用于 ML 模型训练。换句话说，您可能希望将模式文件添加到您的版本控制系统中以供实际使用。在本教程中，为了简单起见，我们将模式复制到预定义的文件系统路径。
import shutil
_schema_filename = 'schema.pbtxt'
SCHEMA_PATH = 'schema'
os.makedirs(SCHEMA_PATH, exist_ok=True)
_generated_path = os.path.join(schema_artifacts[0].uri, _schema_filename)
# Copy the 'schema.pbtxt' file from the artifact uri to a predefined path.
shutil.copy(_generated_path, SCHEMA_PATH)
'schema/schema.pbtxt'
模式文件使用 Protocol Buffer 文本格式 和 TensorFlow 元数据模式协议 的实例。
print(f'Schema at {SCHEMA_PATH}-----')
!cat {SCHEMA_PATH}/*
Schema at schema-----
feature {
name: "body_mass_g"
type: FLOAT
presence {
min_fraction: 1.0
min_count: 1
}
shape {
dim {
size: 1
}
}
}
feature {
name: "culmen_depth_mm"
type: FLOAT
presence {
min_fraction: 1.0
min_count: 1
}
shape {
dim {
size: 1
}
}
}
feature {
name: "culmen_length_mm"
type: FLOAT
presence {
min_fraction: 1.0
min_count: 1
}
shape {
dim {
size: 1
}
}
}
feature {
name: "flipper_length_mm"
type: FLOAT
presence {
min_fraction: 1.0
min_count: 1
}
shape {
dim {
size: 1
}
}
}
feature {
name: "species"
type: INT
presence {
min_fraction: 1.0
min_count: 1
}
shape {
dim {
size: 1
}
}
}
您应该确保根据需要审查并可能编辑模式定义。在本教程中，我们将直接使用生成的模式，不做任何更改。
验证输入示例并训练 ML 模型
我们将回到我们在 简单 TFX 管道教程 中创建的管道，训练 ML 模型并使用生成的模式编写模型训练代码。
我们还将添加一个 ExampleValidator 组件，该组件将根据模式查找传入数据集中的异常和缺失值。
编写模型训练代码
我们需要像在 简单 TFX 管道教程 中一样编写模型代码。
模型本身与之前的教程相同，但这次我们将使用从上一个管道生成的模式，而不是手动指定特征。大多数代码没有更改。唯一的区别是，我们不需要在此文件中指定特征的名称和类型。相反，我们从 schema 文件中读取它们。

如果管道成功完成，您应该看到“INFO:absl:Component Pusher is finished.”。
检查管道的输出
我们已经训练了企鹅的分类模型，并且还在 ExampleValidator 组件中验证了输入示例。我们可以像分析上一个管道一样分析 ExampleValidator 的输出。
metadata_connection_config = tfx.orchestration.metadata.sqlite_metadata_connection_config(
METADATA_PATH)
with Metadata(metadata_connection_config) as metadata_handler:
ev_output = get_latest_artifacts(metadata_handler, PIPELINE_NAME,
'ExampleValidator')
anomalies_artifacts = ev_output[standard_component_specs.ANOMALIES_KEY]
INFO:absl:MetadataStore with DB connection initialized
ExampleValidator 中的 ExampleAnomalies 也可以可视化。
visualize_artifacts(anomalies_artifacts)
您应该看到每个示例拆分的“未发现异常”。因为我们使用了与在此管道中用于模式生成相同的数据，所以这里预计不会出现异常。如果您使用新的传入数据重复运行此管道，ExampleValidator 应该能够找到新数据与现有模式之间的任何差异。
如果发现任何异常，您可以查看您的数据，以检查是否有任何示例不符合您的假设。来自其他组件（如 StatisticsGen）的输出可能会有用。但是，发现的任何异常都不会阻止进一步的管道执行。
