# sr-gpt2
|
||
Test the whole generation capabilities here: https://transformer.huggingface.co/doc/gpt2-large
|
||
Pretrained model on English language using a causal language modeling (CLM) objective. It was introduced in
|
||
[this paper](https://d4mucfpksywv.cloudfront.net/better-language-models/language_models_are_unsupervised_multitask_learners.pdf)
|
||
and first released at [this page](https://openai.com/blog/better-language-models/).
|
||
|
||
## Model description
|
||
sr-gpt2 is a transformers model pretrained on a very large corpus of Serbian data in a self-supervised fashion. This
|
||
means it was pretrained on the raw texts only, with no humans labeling them in any way (which is why it can use lots
|
||
of publicly available data) with an automatic process to generate inputs and labels from those texts. More precisely,
|
||
it was trained to guess the next word in sentences.
|
||
More precisely, inputs are sequences of the continuous text of a certain length and the targets are the same sequence,
|
||
shifted one token (word or piece of the word) to the right. The model uses internally a mask-mechanism to make sure the
|
||
predictions for the token `i` only uses the inputs from `1` to `i` but not the future tokens.
|
||
This way, the model learns an inner representation of the Macedonian language that can then be used to extract features
|
||
useful for downstream tasks. The model is best at what it was pretrained for, however, which is generating texts from a
|
||
prompt.
|
||
|
||
### How to use
|
||
Here is how to use this model to get the features of a given text in PyTorch:
|
||
|
||
import random \
|
||
from transformers import AutoTokenizer, AutoModelWithLMHead
|
||
|
||
tokenizer = AutoTokenizer.from_pretrained('macedonizer/sr-gpt2') \
|
||
model = AutoModelWithLMHead.from_pretrained('macedonizer/sr-gpt2')
|
||
|
||
input_text = 'Ја сам био '
|
||
|
||
if len(input_text) == 0: \
|
||
encoded_input = tokenizer(input_text, return_tensors="pt") \
|
||
output = model.generate( \
|
||
bos_token_id=random.randint(1, 50000), \
|
||
do_sample=True, \
|
||
top_k=50, \
|
||
max_length=1024, \
|
||
top_p=0.95, \
|
||
num_return_sequences=1, \
|
||
) \
|
||
else: \
|
||
encoded_input = tokenizer(input_text, return_tensors="pt") \
|
||
output = model.generate( \
|
||
**encoded_input, \
|
||
bos_token_id=random.randint(1, 50000), \
|
||
do_sample=True, \
|
||
top_k=50, \
|
||
max_length=1024, \
|
||
top_p=0.95, \
|
||
num_return_sequences=1, \
|
||
)
|
||
|
||
decoded_output = [] \
|
||
for sample in output: \
|
||
decoded_output.append(tokenizer.decode(sample, skip_special_tokens=True))
|
||
|
||
print(decoded_output) |
