Installation

1) Clone the repository

gh repo clone serpapi/automatic-images-classifier-generator

2)Open a SerpApi Account (Free Credits Available upon Registration)

3)Download and Install Couchbase

5) Install required Python Libraries

pip install -r requirements.txt

6) Fillcredentials.py file with your server credentials, andSerpApi credentials

7) Run Setup Server File

python setup_server.py

8) Run the FastAPI Server

uvicorn main:app --host 0.0.0.0 --port 8000

or you may simply use a debugging server by clicking onmain.py and running a degugging server:

9) Optionally run the tests:

pytest test_main.py

Basic Usage of Machine Learning Tools

1) Head tolocalhost:8000/docs
2) Useadd_to_db endpoint to call to update image database
3) Usetrain endpoint to train a model. The trained model will be saved onmodels folder when the training is complete. The training is an async process. Keep an eye out for terminal outputs for the progression.
4) Usetest endpoint to test a model.
5) Usefind_attempt endpoint to fetch the data on the training and testing process (losses at each epoch, accuracy etc.)

Adding SERP Images to Storage Server

add_to_db

User can make singular searches withSerpApi Images Scraper API, and automatically add them to local image storage server.

multiple_query

User can make multiple searches with SerpApi Images Scraper API, and automatically add them to local image storage server.

Training a Model

User can train a model with a customized dictionary fromtrain endpoint.

train

Tips for Criterion

• criterion key is responsible for calling a loss function.
• If user only provides the name of the criterion(loss function), it will be used without parameters.
• Some string inputs(especially if the user calls an external class from Pytorch), should be double quoted like"'Parameter Value'".
• User may find the information on the support forLoss Functions later in the documentation.

Tips for Optimizer

• optimizer key is responsible for calling an optimizer.
• If user only provides the name of the optimizer, it will be used without parameters.
• Some string inputs(especially if the user calls an external class from Pytorch), should be double quoted like"'Parameter Value'".
• User may find the information on the support forOptimizers later in the documentation.

Tips for Image Operations (PIL Image Functions)

• image_ops key is responsible for calling PIL operations on the input.
• PIL integration is only supportive for Pytorch Transforms(transform,target_transform keys) integration. It should be used for secondary purposes. Many of the functions PIL supports is already wrapped in Pytorch Transforms.
• Each dictionary represents a separate operation.
• Some string inputs(especially if user calls an external class from PIL), should be double quoted like"'Parameter Value'"
• User may find the information on the support forOptimizers later in the documentation.

Tips for Pytorch Transforms

• transform andtarget_transform keys are both responsible calling Pytorch Transforms. First one is for input, the second one is for label respectively.
• Transforms integration is the main integration responsible for preprocessing images, and labels before training.
• Each key in the dictionary represents a separate operation.
• Order of the keys represent the order of sequential transforms to be applied.
• Transforms without a parameter should be given the valueTrue to be passed.
• Some string inputs(especially if the user calls an external class from Pytorch), should be double quoted like"'Parameter Value'"
• User may find the information on the support forTransforms later in the documentation.

Tips for Label Names

• label_names is responsible for declaring label names.
• Label Names should be present in the Image Database Storage Server created by the user.
• If the user providedheight andwidth of images to be scraped inadd_to_db ormultiple_queries endpoints, the label name should be written with an addendumimagesize:heightxwidth. Otherwise the images without certain classification will be fetched if they are present in the server.
• Vectorized versions of labels could be transformed usingtarget_transform

Tips for Model

• model key is responsible for the calling or creation of a model.
• Ifname key is provided, a previously defined class name withinmodels.py will be called, andlayers key will be ignored.
• Iflayers key is provided, andname key is not provided, a sequential layer creation will follow.
• Each dictionary in thelayers array represents a training layer.
• User may useauto value for the input parameter to automatically get the past output layer in a limited support. For now, it is only supported for same kinds of layers.
• User may usen_labels to indicate the number of labels in the final layer.
• User may find the information on the support forLayers later in the documentation.

Testing a Model

test

User may test the trained model by fetching random images that have the same classifications as labels.

Getting Information on the Training and Testing of the Model

find_attempt

Each time a user usestrain endpoint, anAttempt object is created in the database. This object is also updated on each timetest endpoint is used. Also, user may automatically check the status of the training from this object.

• At the beginning of each training, thestatus of the object will beTraining.
• At the end of each training, thestatus of the object will beTrained
• At the end of each testing, thestatus of the object will beComplete

Support for Various Elements

Below are the different functions, and algorithms supported. Data has been derived from the results oftest_main.py unit tests. Functions, and algorithms not present in the list may or may not work. Feel free to try them out.

Keypoints for the State of the Machine Learning Tool and Its Future Roadmap

• For now, the scope of this software only supports image datasets, and the aim is to create image-classifying machine learning models at scale. The broader purpose is to achieve better computer vision by scalability. Future plans include adding the other basic input tensor types for data science, data analysis, data analytics, or artificial intelligence projects. The open source software could be repurposed to achieve other kinds of tasks such as regression, natural language processing, or any other popular machine learning use cases.

• There are no future plans to support any other programming languages such as Java, Javascript, C/C++, etc. The only supported language will be Python for the foreseeable future. The ability to support other efficient databases on big data such as SQL on Hadoop could be a topic for discussion. Also, the ability to add multiple images from local storage to the storage server is in the future plans.

• The only Machine Learning framework supported is Pytorch. There are plans to extend support for some other machine learning libraries and software such as Tensorflow, Keras, Scikit-Learn, Apache Spark, Scipy, Apache Mahout, Accord.NET, Weka, etc. in the future. Already used libraries such as google-image-results, NumPy, etc. may be utilized further in the future.

• To keep the software user-friendly, the device to train the model on (GPU(CUDA), or CPU) is automatically selected. Also, there are plans to create data visualizations of different models in interactive graphs that can be understood by seasoned data scientists or beginners alike in the future. The drag-and-drop type machine learning software libraries for model creation are not anticipated to be implemented.

• This is open-source software designed for local use. The effects or cost of deployment to cloud servers such as AWS, Google Cloud, etc., or integrating it for machine learning applications with the cloud solutions such as Amazon Sagemaker, IBM Watson, Microsoft’s Azure Machine Learning, and Jupyter Notebook hasn’t been tested yet. Use it at your own discretion. The future plans include some of the large-scale ml tools to be implemented.

• The workflows for future plans above may or may not be implemented depending on the schedule of events, support from other contributors, and its overall use in automation. Multiple machine learning projects with a tutorial will be released explaining machine learning tools.

Conclusion

I am grateful to the readers for their attention, andBrilliant People of SerpApi for making this blog post possible. In the coming weeks, we will embark for a basic open source client tool that is not using any storage database, but usingautomatic-images-classifier-generator at its core.
