/Users/jgongac/miniforge3/envs/deeplearning/lib/python3.8/site-packages/torch/_C.cpython-38-darwin.so: mach-o, but wrong architecture 这是咋回事。我用的是miniforge创的3.8.8的环境。 感谢 2021-04-10 回复喜欢 托亚 transformers是不是并不支持GPU版的tensorflow?import tensorflow as tf,...
模型本身是一个常规的Pytorchnn.Module或TensorFlowtf.keras.Model(取决于你的后端),可以常规方式使用。这个教程解释了如何将这样的模型整合到经典的 PyTorch 或 TensorFlow 训练循环中,或是如何使用我们的Trainer训练器)API 来在一个新的数据集上快速微调。 为什么要用 transformers? 便于使用的先进模型: NLU 和 NLG ...
Transformers works with Python 3.9+PyTorch2.1+,TensorFlow2.6+, andFlax0.4.1+. Create and activate a virtual environment withvenvoruv, a fast Rust-based Python package and project manager. # venvpython-mvenv.my-envsource.my-env/bin/activate# uvuvvenv.my-envsource.my-env/bin/activate ...
tokens in the right way for each model.with torch.no_grad(): last_hidden_states = model(input_ids)[0] # Models outputs are now tuples #Each architecture is provided with several class for fine-tuning on down-stream tasks, e.g.BERT_MODEL_CLASSES = [BertModel, BertForPreTraining, Ber...
有时会遇到将学习到的模型在这两个框架间进行迁移的问题,所以需要对Transformers的pytoch_model.bin和TensorFlow的bert_model.ckpt预训练模型进行互转。Transformers库是提供了相关py文件,但是一些细节需要根据自己的模型和需求来改写代码,以免出错。 原始的Roberta-Large的参数分析 ...

We provide examples for each architecture to reproduce the results published by its original authors. Model internals are exposed as consistently as possible. Model files can be used independently of the library for quick experiments. Why shouldn't I use Transformers?
一般正常,因为if you are initializing BertModel from the checkpoint of a model trained on another task or with another architecture。 示例1: 通过BertForMaskedLM finetune 加载bert-base-uncased或者bert-base-chinese模型 进行预训练时,提示Some weights of the model checkpoint at ./models/bert-base-unca...
