The steps for combining MLFlow and the TensorFlow 2.x Object Detection API are:
Here are the more detailed steps:
pip install tensorflow==2.4.1
pip install mlflow
pip install pillow lxml Cython contextlib2
pip install matplotlib pandas tf-slim
Download a pre-trained model from TensorFlow Model Zoo. You can choose an object detection model that fits your needs, depending on the trade-offs you want to make between speed, accuracy, and training time. The pre-trained models are available in the TensorFlow Model Zoo.
Create a configuration file for the model. The configuration file should define the details of the model architecture and the training and evaluation settings. You can use a sample configuration file from the TensorFlow Object Detection API, and modify it as needed. Save the configuration file as a .config file.
Create a script to run the training process and log the results to MLFlow. In the training script, import the necessary modules, define the model architecture, read the configuration file, set up the training and evaluation settings, and run the training process. You also need to set up MLFlow logging within the script, so that the metrics and artifacts produced during the training can be tracked in MLFlow. An example script is provided below:
import os
import tensorflow as tf
from object_detection.utils import dataset_util, label_map_util
from object_detection import model_main_tf2
import mlflow
# Set up MLFlow tracking
mlflow.set_tracking_uri("http://localhost:5000")
mlflow.set_experiment("my_experiment")
with mlflow.start_run():
# Set up the model
model_dir = "/path/to/model/directory"
pipeline_config_path = "/path/to/pipeline/config"
model_main_tf2.FLAGS.pipeline_config_path = pipeline_config_path
model_main_tf2.FLAGS.model_dir = model_dir
# Set up the training settings
num_train_steps = 10000
num_eval_steps = 1000
checkpoint_every_n = 5000
eval_interval_secs = 300
# Run the training
model_main_tf2.FLAGS.num_train_steps = num_train_steps
model_main_tf2.FLAGS.num_eval_steps = num_eval_steps
model_main_tf2.FLAGS.checkpoint_every_n = checkpoint_every_n
model_main_tf2.FLAGS.eval_interval_secs = eval_interval_secs
model_main_tf2.main(None)
# Log the metrics and artifacts to MLFlow
mlflow.log_param("model_dir", model_dir)
mlflow.log_param("pipeline_config_path", pipeline_config_path)
mlflow.log_param("num_train_steps", num_train_steps)
mlflow.log_param("num_eval_steps", num_eval_steps)
mlflow.log_param("checkpoint_every_n", checkpoint_every_n)
mlflow.log_param("eval_interval_secs", eval_interval_secs)
mlflow.log_artifacts(model_dir)
python train.py
The training process begins, and the metrics and artifacts produced during the process are logged to MLFlow. You can monitor the training progress in the MLFlow UI, and compare the performance of different models or training settings by organizing the runs in the UI.
