🚀 Installation

Install from PyPi:

pip install -U clarifai

Install from Source:

git clone https://github.com/Clarifai/clarifai-python.git
cd clarifai-python
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

📝 Getting started

Clarifai uses Personal Access Tokens(PATs) to validate requests. You can create and manage PATs under your Clarifai account security settings.

• 🔗 Create PAT: Log into Portal → Profile Icon → Security Settings → Create Personal Access Token → Set the scopes → Confirm

• 🔗 Get User ID: Log into Portal → Profile Icon → Account → Profile → User-ID

Export your PAT as an environment variable. Then, import and initialize the API Client.

Set PAT as environment variable through terminal:

export CLARIFAI_PAT={your personal access token}

# Note: CLARIFAI_PAT must be set as env variable.
from clarifai.client.user import User
client = User(user_id="user_id")

# Get all apps
apps_generator = client.list_apps()
apps = list(apps_generator)

OR

PAT can be passed as constructor argument

from clarifai.client.user import User
client = User(user_id="user_id", pat="your personal access token")

💾 Interacting with Datasets

Clarifai datasets help in managing datasets used for model training and evaluation. It provides functionalities like creating datasets,uploading datasets, retrying failed uploads from logs and exporting datasets as .zip files.

# Note: CLARIFAI_PAT must be set as env variable.

# Create app and dataset
app = client.create_app(app_id="demo_app", base_workflow="Universal")
dataset = app.create_dataset(dataset_id="demo_dataset")

# execute data upload to Clarifai app dataset
from clarifai.datasets.upload.loaders.coco_detection import COCODetectionDataLoader
coco_dataloader = COCODetectionDataLoader("images_dir", "coco_annotation_filepath")
dataset.upload_dataset(dataloader=coco_dataloader, get_upload_status=True)


#Try upload and record the failed outputs in log file.
from clarifai.datasets.upload.utils import load_module_dataloader
cifar_dataloader = load_module_dataloader('./image_classification/cifar10')
dataset.upload_dataset(dataloader=cifar_dataloader,
                       get_upload_status=True,
                       log_warnings =True)

#Retry upload from logs for `upload_dataset`
# Set retry_duplicates to True if you want to ingest failed inputs due to duplication issues. by default it is set to 'False'.
dataset.retry_upload_from_logs(dataloader=cifar_dataloader, log_file_path='log_file.log',
                               retry_duplicates=True,
                               log_warnings=True)

#upload text from csv
dataset.upload_from_csv(csv_path='csv_path', input_type='text', csv_type='raw', labels=True)

#upload data from folder
dataset.upload_from_folder(folder_path='folder_path', input_type='text', labels=True)

# Export Dataset
dataset.export(save_path='output.zip')

💾 Interacting with Inputs

You can use inputs() for adding and interacting with input data. Inputs can be uploaded directly from a URL or a file. You can also view input annotations and concepts.

Input Upload

# Note: CLARIFAI_PAT must be set as env variable.
from clarifai.client.user import User
app = User(user_id="user_id").app(app_id="app_id")
input_obj = app.inputs()

#input upload from url
input_obj.upload_from_url(input_id = 'demo', image_url='https://samples.clarifai.com/metro-north.jpg')

#input upload from filename
input_obj.upload_from_file(input_id = 'demo', video_file='demo.mp4')

# text upload
input_obj.upload_text(input_id = 'demo', raw_text = 'This is a test')

Input Listing

#listing inputs
input_generator = input_obj.list_inputs(page_no=1,per_page=10,input_type='image')
inputs_list = list(input_generator)

#listing annotations
annotation_generator = input_obj.list_annotations(batch_input=inputs_list)
annotations_list = list(annotation_generator)

#listing concepts
all_concepts = list(app.list_concepts())

Input Download

#listing inputs
input_generator = input_obj.list_inputs(page_no=1,per_page=1,input_type='image')
inputs_list = list(input_generator)

#downloading_inputs
input_bytes = input_obj.download_inputs(inputs_list)
with open('demo.jpg','wb') as f:
  f.write(input_bytes[0])

🧠 Interacting with Models

The Model Class allows you to perform predictions using Clarifai models. You can specify which model to use by providing the model URL or ID. This gives you flexibility in choosing models. The App Class also allows listing of all available Clarifai models for discovery. For greater control over model predictions, you can pass in an output_config to modify the model output as demonstrated below.

Model Predict

# Note: CLARIFAI_PAT must be set as env variable.
from clarifai.client.model import Model

"""
Get Model information on details of model(description, usecases..etc) and info on training or
# other inference parameters(eg: temperature, top_k, max_tokens..etc for LLMs)
"""
gpt_4_model = Model("https://clarifai.com/openai/chat-completion/models/GPT-4")
print(gpt_4_model)


# Model Predict
model_prediction = Model("https://clarifai.com/anthropic/completion/models/claude-v2").predict_by_bytes(b"Write a tweet on future of AI")

# Customizing Model Inference Output
model_prediction = gpt_4_model.predict_by_bytes(b"Write a tweet on future of AI", inference_params=dict(temperature=str(0.7), max_tokens=30))
# Return predictions having prediction confidence > 0.98
model_prediction = model.predict_by_filepath(filepath="local_filepath", output_config={"min_value": 0.98}) # Supports image, text, audio, video

# Supports prediction by url
model_prediction = model.predict_by_url(url="url") # Supports image, text, audio, video

# Return predictions for specified interval of video
video_input_proto = [input_obj.get_input_from_url("Input_id", video_url=BEER_VIDEO_URL)]
model_prediction = model.predict(video_input_proto, output_config={"sample_ms": 2000})

Model Training

# Note: CLARIFAI_PAT must be set as env variable.
from clarifai.client.app import App
from clarifai.client.model import Model

"""
Create model with trainable model_type
"""
app = App(user_id="user_id", app_id="app_id")
model = app.create_model(model_id="model_id", model_type_id="visual-classifier")
               (or)
model = Model('url')

"""
List training templates for the model_type
"""
templates = model.list_training_templates()
print(templates)

"""
Get parameters for the model.
"""
params = model.get_params(template='classification_basemodel_v1', save_to='model_params.yaml')

"""
Update the model params yaml and pass it to model.train()
"""
model_version_id = model.train('model_params.yaml')

"""
Training status and saving logs
"""
status = model.training_status(version_id=model_version_id,training_logs=True)
print(status)

Export your trained model

Model Export feature enables you to package your trained model into a model.tar file. This file enables deploying your model within a Triton Inference Server deployment.

from clarifai.client.model import Model

model = Model('url')
model.export('output/folder/')

Evaluate your trained model

When your model is trained and ready, you can evaluate by the following code

from clarifai.client.model import Model

model = Model('url')
model.evaluate(dataset_id='your-dataset-id')

Compare the evaluation results of your models.

from clarifai.client.model import Model
from clarifai.client.dataset import Dataset
from clarifai.utils.evaluation import EvalResultCompare

models = ['model url1', 'model url2'] # or [Model(url1), Model(url2)]
dataset = 'dataset url' # or Dataset(dataset_url)

compare = EvalResultCompare(
  models=models,
  datasets=dataset,
  attempt_evaluate=True # attempt evaluate when the model is not evaluated with the dataset
  )
compare.all('output/folder/')

Models Listing

# Note: CLARIFAI_PAT must be set as env variable.

# List all model versions
all_model_versions = list(model.list_versions())

# Go to specific model version
model_v1 = client.app("app_id").model(model_id="model_id", model_version_id="model_version_id")

# List all models in an app
all_models = list(app.list_models())

# List all models in community filtered by model_type, description
all_llm_community_models = App().list_models(filter_by={"query": "LLM",
                                                        "model_type_id": "text-to-text"}, only_in_app=False)
all_llm_community_models = list(all_llm_community_models)

🔥 Interacting with Workflows

Workflows offer a versatile framework for constructing the inference pipeline, simplifying the integration of diverse models. You can use the Workflow class to create and manage workflows using YAML configuration. For starting or making quick adjustments to existing Clarifai community workflows using an initial YAML configuration, the SDK provides an export feature.

Workflow Predict

# Note: CLARIFAI_PAT must be set as env variable.
from clarifai.client.workflow import Workflow

# Workflow Predict
workflow = Workflow("workflow_url") # Example: https://clarifai.com/clarifai/main/workflows/Face-Sentiment
workflow_prediction = workflow.predict_by_url(url="url") # Supports image, text, audio, video

# Customizing Workflow Inference Output
workflow = Workflow(user_id="user_id", app_id="app_id", workflow_id="workflow_id",
                  output_config={"min_value": 0.98}) # Return predictions having prediction confidence > 0.98
workflow_prediction = workflow.predict_by_filepath(filepath="local_filepath") # Supports image, text, audio, video

Workflows Listing

# Note: CLARIFAI_PAT must be set as env variable.

# List all workflow versions
all_workflow_versions = list(workflow.list_versions())

# Go to specific workflow version
workflow_v1 = Workflow(workflow_id="workflow_id", workflow_version=dict(id="workflow_version_id"), app_id="app_id", user_id="user_id")

# List all workflow in an app
all_workflow = list(app.list_workflow())

# List all workflow in community filtered by description
all_face_community_workflows = App().list_workflows(filter_by={"query": "face"}, only_in_app=False) # Get all face related workflows
all_face_community_workflows = list(all_face_community_workflows)

Workflow Create

Create a new workflow specified by a yaml config file.

# Note: CLARIFAI_PAT must be set as env variable.
from clarifai.client.app import App
app = App(app_id="app_id", user_id="user_id")
workflow = app.create_workflow(config_filepath="config.yml")

Workflow Export

Export an existing workflow from Clarifai as a local yaml file.

# Note: CLARIFAI_PAT must be set as env variable.
from clarifai.client.workflow import Workflow
workflow = Workflow("https://clarifai.com/clarifai/main/workflows/Demographics")
workflow.export('demographics_workflow.yml')

🔍 Search

Smart Image Search

Clarifai's Smart Search feature leverages vector search capabilities to power the search experience. Vector search is a type of search engine that uses vectors to search and retrieve text, images, and videos.

Instead of traditional keyword-based search, where exact matches are sought, vector search allows for searching based on visual and/or semantic similarity by calculating distances between vector embedding representations of the data.

Here is an example of how to use vector search to find similar images:

# Note: CLARIFAI_PAT must be set as env variable.
from clarifai.client.search import Search
search = Search(user_id="user_id", app_id="app_id", top_k=1, metric="cosine")

# Search by image url
results = search.query(ranks=[{"image_url": "https://samples.clarifai.com/metro-north.jpg"}])

for data in results:
  print(data.hits[0].input.data.image.url)

Smart Text Search

Smart Text Search is our proprietary feature that uses deep learning techniques to sort, rank, and retrieve text data based on their content and semantic similarity.

Here is an example of how to use Smart Text Search to find similar text:

# Note: CLARIFAI_PAT must be set as env variable.

# Search by text
results = search.query(ranks=[{"text_raw": "I love my dog"}])

Filters

You can use filters to narrow down your search results. Filters can be used to filter by concepts, metadata, and Geo Point.

It is possible to add together multiple search parameters to expand your search. You can even combine negated search terms for more advanced tasks.

For example, you can combine two concepts as below.

# query for images that contain concept "deer" or "dog"
results = search.query(ranks=[{"image_url": "https://samples.clarifai.com/metro-north.jpg"}],
                        filters=[{"concepts": [{"name": "deer", "value":1},
                                              {"name": "dog", "value":1}]}])

# query for images that contain concepts "deer" and "dog"
results = search.query(ranks=[{"image_url": "https://samples.clarifai.com/metro-north.jpg"}],
                        filters=[{"concepts": [{"name": "deer", "value":1}],
                                  "concepts": [{"name": "dog", "value":1}]}])

Input filters allows to filter by input_type, status of inputs and by inputs_dataset_id

results = search.query(filters=[{'input_types': ['image', 'text']}])

Pagination

Below is an example of using Search with Pagination.

# Note: CLARIFAI_PAT must be set as env variable.
from clarifai.client.search import Search
search = Search(user_id="user_id", app_id="app_id", metric="cosine", pagination=True)

# Search by image url
results = search.query(ranks=[{"image_url": "https://samples.clarifai.com/metro-north.jpg"}],page_no=2,per_page=5)

for data in results:
  print(data.hits[0].input.data.image.url)

Retrieval Augmented Generation (RAG)

You can setup and start your RAG pipeline in 4 lines of code. The setup method automatically creates a new app and the necessary components under the hood. By default it uses the mistral-7B-Instruct model.

from clarifai.rag import RAG

rag_agent = RAG.setup(user_id="USER_ID")
rag_agent.upload(folder_path="~/docs")
rag_agent.chat(messages=[{"role":"human", "content":"What is Clarifai"}])

If you have previously run the setup method, you can instantiate the RAG class with the prompter workflow URL:

from clarifai.rag import RAG

rag_agent = RAG(workflow_url="WORKFLOW_URL")
