paddlenlp
安装python3.11版本
conda create -n python311 python=3.11
激活python
conda activate python311
安装paddlepaddle
conda install paddlepaddle==3.0.0b0 -c paddle
pip install paddlenlp==3.0.0b0 -U -i https://pypi.tuna.tsinghua.edu.cn/simple
windows下提示:
AttributeError: module 'mmap' has no attribute 'MAP_PRIVATE'
解决方法:
E:\Anaconda3\envs\python311\Lib\site-packages\paddlenlp\utils\safetensors.py
修改280行:
self.file_mmap = mmap.mmap(self.file.fileno(), 0, access=mmap.MAP_PRIVATE)
为
self.file_mmap = mmap.mmap(self.file.fileno(), 0, access=mmap.ACCESS_READ)
错误提示:RuntimeError: (NotFound) The kernel with key (CPU, Undefined(AnyLayout), float16) of kernel multiply
is not registered. Selected wrong DataType float16
. Paddle support following DataTypes: complex64, bool, bfloat16, complex128, float32, int32, float64, int64
原因:
在CPU环境调用时,模型支持dtype为float32或者float64;
在GPU环境(非Ampere架构)调用时,模型支持dtype为float16、float32或者float64;
在GPU环境(Ampere及后续架构)调用时,模型支持dtype为bfloat16、float16、float32或者float64;
测试代码:

from modelscope import snapshot_download
os.environ["HF_ENDPOINT"] = "https://hf-mirror.com"
os.environ["TF_ENABLE_ONEDNN_OPTS"] = "0"
from paddlenlp.transformers import AutoTokenizer, AutoModelForCausalLM
model_dir = snapshot_download("Qwen/Qwen2-0.5B")
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2-0.5B",trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen2-0.5B", dtype="float32")
input_features = tokenizer("你好!请自我介绍一下。", return_tensors="pd")
outputs = model.generate(**input_features, max_length=128)
tex=tokenizer.batch_decode(outputs[0])
print(tex)
