How to Visualize Clarifai Data in Python with pandas
The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData API Driver for Python, the pandas & Matplotlib modules, and the SQLAlchemy toolkit, you can build Clarifai-connected Python applications and scripts for visualizing Clarifai data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to Clarifai data, execute queries, and visualize the results.
With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Clarifai data in Python. When you issue complex SQL queries from Clarifai, the driver pushes supported SQL operations, like filters and aggregations, directly to Clarifai and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).
Connecting to Clarifai Data
Connecting to Clarifai data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.
Start by setting the Profile connection property to the location of the Clarifai Profile on disk (e.g. C:\profiles\Clarifai.apip). Next, set the ProfileSettings connection property to the connection string for Clarifai (see below).
Clarifai API Profile Settings
Clarifai uses Personal Access Tokens (PATs) for authentication. To obtain a PAT:
- Log in to your Clarifai account at https://clarifai.com.
- Navigate to your profile settings and select Security.
- Click Create Personal Access Token.
- Select the required scopes and click Create Token.
- Copy the generated token (it will only be shown once).
After obtaining your Personal Access Token, set the following connection properties:
- AuthScheme: Set this to APIKey.
Set the following in the ProfileSettings connection property:
- APIKey: Set this to your Clarifai Personal Access Token (PAT).
Follow the procedure below to install the required modules and start accessing Clarifai through Python objects.
Install Required Modules
Use the pip utility to install the pandas & Matplotlib modules and the SQLAlchemy toolkit:
pip install pandas pip install matplotlib pip install sqlalchemy
Be sure to import the module with the following:
import pandas import matplotlib.pyplot as plt from sqlalchemy import create_engine
Visualize Clarifai Data in Python
You can now connect with a connection string. Use the create_engine function to create an Engine for working with Clarifai data.
engine = create_engine("api:///?Profile=C:\profiles\Clarifai.apip&AuthScheme=APIKey&ProfileSettings='APIKey=your_personal_access_token'")
Execute SQL to Clarifai
Use the read_sql function from pandas to execute any SQL statement and store the resultset in a DataFrame.
df = pandas.read_sql("SELECT Id, Name FROM Apps WHERE UserId = 'my-user-id'", engine)
Visualize Clarifai Data
With the query results stored in a DataFrame, use the plot function to build a chart to display the Clarifai data. The show method displays the chart in a new window.
df.plot(kind="bar", x="Id", y="Name") plt.show()
