### How to use |
|
|
|
You can use this model directly with a pipeline for text generation. Since the generation relies on some randomness, we |
|
set a seed for reproducibility: |
|
|
|
```python |
|
>>> from transformers import pipeline, set_seed |
|
>>> generator = pipeline('text-generation', model='malteos/gpt2-xl-wechsel-german') |
|
>>> set_seed(42) |
|
>>> generator("Hello, I'm a language model,", max_length=30, num_return_sequences=5) |
|
|
|
[{'generated_text': "Hello, I'm a language model, a language for thinking, a language for expressing thoughts."}, |
|
{'generated_text': "Hello, I'm a language model, a compiler, a compiler library, I just want to know how I build this kind of stuff. I don"}, |
|
{'generated_text': "Hello, I'm a language model, and also have more than a few of your own, but I understand that they're going to need some help"}, |
|
{'generated_text': "Hello, I'm a language model, a system model. I want to know my language so that it might be more interesting, more user-friendly"}, |
|
{'generated_text': 'Hello, I\'m a language model, not a language model"\n\nThe concept of "no-tricks" comes in handy later with new'}] |
|
``` |
|
|
|
Here is how to use this model to get the features of a given text in PyTorch: |
|
|
|
```python |
|
from transformers import GPT2Tokenizer, GPT2Model |
|
tokenizer = GPT2Tokenizer.from_pretrained('malteos/gpt2-xl-wechsel-german') |
|
model = GPT2Model.from_pretrained('malteos/gpt2-xl-wechsel-german') |
|
text = "Replace me by any text you'd like." |
|
encoded_input = tokenizer(text, return_tensors='pt') |
|
output = model(**encoded_input) |
|
``` |
|
|
|
