🚀 How to build a dummy model

This guide shows you how to build a dummy model using the transformers library. It demonstrates the process of creating a model, saving it, and converting it to a TensorFlow model.

🚀 Quick Start

Prerequisites

Make sure you have the transformers library installed.

Building the Dummy Model

The following code snippet shows how to build a dummy model:

from transformers import BertConfig, BertForMaskedLM, BertTokenizer, TFBertForMaskedLM

SMALL_MODEL_IDENTIFIER = "julien-c/bert-xsmall-dummy"
DIRNAME = "./bert-xsmall-dummy"

config = BertConfig(10, 20, 1, 1, 40)

model = BertForMaskedLM(config)
model.save_pretrained(DIRNAME)

tf_model = TFBertForMaskedLM.from_pretrained(DIRNAME, from_pt=True)
tf_model.save_pretrained(DIRNAME)

# Slightly different for tokenizer.
# tokenizer = BertTokenizer.from_pretrained(DIRNAME)
# tokenizer.save_pretrained()

Explanation

Import necessary libraries: Import the required classes from the transformers library.
Set model identifier and directory: Define the model identifier and the directory where the model will be saved.
Configure the model: Create a BertConfig object with the desired parameters.
Create the model: Instantiate a BertForMaskedLM model with the configuration.
Save the PyTorch model: Save the PyTorch model to the specified directory.
Convert to TensorFlow model: Load the saved PyTorch model and convert it to a TensorFlow model.
Save the TensorFlow model: Save the TensorFlow model to the same directory.

💻 Usage Examples

Basic Usage

The provided code above is a basic example of building a dummy model. You can use it as a starting point for your own projects.

Advanced Usage

You can modify the BertConfig parameters to customize the model architecture. For example, you can change the number of layers, hidden size, etc.

# Example of customizing the model configuration
config = BertConfig(num_hidden_layers=2, hidden_size=128, num_attention_heads=4, intermediate_size=512)
model = BertForMaskedLM(config)
# Rest of the code remains the same
