尝试 Example 时 ModuleNotFoundError: No module named 'paddle'

尝试 Example 时遇到问题，按 https://github.com/PaddlePaddle/PaddleNLP/tree/develop/examples/code_generation/codegen#githubcopilot%E6%8F%92%E4%BB%B6%E9%85%8D%E7%BD%AE

先 clone 代码，然后

cd /examples/code_generation/codegen
pip3 install -r requirements.txt # 注意是 pip3 ，否则报 ModuleNotFoundError: No module named 'uvicorn'
python3 codegen_server.py # 注意是 python3 ，否则报 command not found: python

之后报错

Traceback (most recent call last):
  File "/Users/lindongwu/Desktop/github/PaddleNLP/examples/code_generation/codegen/codegen_server.py", line 18, in <module>
    import paddle
ModuleNotFoundError: No module named 'paddle'

pip3 install --upgrade paddlenlp

也无效

[linonetwo]

先按照 https://www.paddlepaddle.org.cn/install/quick 安装 paddlepaddle ，再按照本仓库 readme 装 paddlenlp 即可

pip3 install paddlepaddle==2.3.2 -i https://pypi.tuna.tsinghua.edu.cn/simple
pip3 install --upgrade paddlenlp

上面这样安的 paddlepaddle 会报错：

    raise ValueError("The device should not be 'gpu', "
ValueError: The device should not be 'gpu', since PaddlePaddle is not compiled with CUDA

将 codegen_server.py 脚本里的配置改为 CPU 执行即可：

class DefaultConfig:
    model_name_or_path = "Salesforce/codegen-350M-mono"
    device = "cpu"

这样会报错

    re = try_import("regex")
  File "/usr/local/lib/python3.9/site-packages/paddle/utils/lazy_import.py", line 40, in try_import
    raise ImportError(err_msg)
ImportError: Failed importing regex. This likely means that some paddle modules require additional dependencies that have to be manually installed (usually with `pip install regex`). 

需要

pip3 install regex

之后再次 python3 codegen_server.py 就会自动下很多模型，然后就可以运行了

。。。

还有注意 python 各版本之间已安装依赖不互通，例如 brew upgrade 升级了 py 后，需要重新走一遍上面的步骤。
