from transformers import T5Tokenizer, T5ForConditionalGeneration
tokenizer = T5Tokenizer.from_pretrained("AlexWortega/Flan_base_translated")
model = T5ForConditionalGeneration.from_pretrained("AlexWortega/Flan_base_translated")
input_text = "translate English to German: How old are you?"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids
outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0]))
Running the model on a GPU

Uses
Direct Use and Downstream Use
The authors write in the original paper's model card that:
The primary use is research on language models, including: research on zero-shot NLP tasks and in-context few-shot learning NLP tasks, such as reasoning, and question answering; advancing fairness and safety research, and understanding limitations of current large language models
See the research paper for further details.
Out-of-Scope Use

Bias, Risks, and Limitations
The information below in this section are copied from the model's official model card:
Language models, including Flan-T5, can potentially be used for language generation in a harmful way, according to Rae et al. (2021). Flan-T5 should not be used directly in any application, without a prior assessment of safety and fairness concerns specific to the application.
Ethical considerations and risks
Flan-T5 is fine-tuned on a large corpus of text data that was not filtered for explicit content or assessed for existing biases. As a result the model itself is potentially vulnerable to generating equivalently inappropriate content or replicating inherent biases in the underlying data.
Known Limitations
Flan-T5 has not been tested in real world applications.
Sensitive Use:
Flan-T5 should not be applied for any unacceptable use cases, e.g., generation of abusive speech.
