Replicate Hello World with Cog 🌍
Welcome to the replicate-hello-world
project! This is a simple “Hello World” function designed to help me get started with Cog and Replicate.
If you’re also new to Cog and Replicate you should check out the code!
Project Overview 🔮
This project contains a Python script that defines a greeting predictor. The predictor is a simple function that takes a name as input and returns a greeting message.
If you’d like details on how to push your own HelloWorld model, read on! ⚙️
Otherwise, just type in a "name"
into the Replicate instance! 🖍️
Predictor Class Overview 🚀
The Predictor
class in our script extends the BasePredictor
class from the Cog library. It consists of two main methods:
-
setup()
: This method is called once during the initialization of thePredictor
instance. It’s used to set up any necessary attributes or data for thePredictor
. In our case, we’re initializing agreetings
attribute with the string “Hello”. -
predict(name: str)
: This method is the core of our model. It’s called to make predictions based on the providedname
. It uses thegreetings
attribute of the instance and the providedname
to create a greeting message. Thename
is passed as an argument to thepredict
method.
Here’s a simple example of how to use the Predictor
:
> p = Predictor()
> print(p.predict("Sakib"))
Hello, Sakib!
Running the Model Locally 🏡
To run the model locally, you will first need to build it using Cog. You can do this by running the following command in your terminal:
$ cog build
This command will build a Docker image of the model.
After building the model, you can make a prediction by running the following command:
$ cog predict -i name="Sakib"
This command will start a Docker container of the model and make a prediction using the input you provided ("Sakib"
in this case). You should see output similar to the following:
Running prediction...
Hello, Sakib!
This indicates that the model successfully made a prediction.
Note that the specifics of how to use the cog
command may depend on your setup and environment, so be sure to consult the Cog documentation for more detailed information.
