直接pip安装paddlerocr会报错

(paddal_1) C:\Users\Lenovo>pip install "paddleocr>=2.0.1"

报错显示

Installing collected packages: protobuf
  Attempting uninstall: protobuf
    Found existing installation: protobuf 3.20.0
    Uninstalling protobuf-3.20.0:
      Successfully uninstalled protobuf-3.20.0
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
paddlepaddle-gpu 2.4.2.post117 requires protobuf<=3.20.0,>=3.1.0, but you have protobuf 3.20.3 which is incompatible.
Successfully installed protobuf-3.20.3

原因是protobuf这个包与我的paddlepaddle-gpu不兼容

尝试一：降低版本（失败）

(paddal_1) C:\Users\Lenovo>pip install protobuf==3.20.0

还是报错 

尝试二：安装onnx包

(paddal_1) C:\Users\Lenovo>pip install onnx==1.12.0

然后再次执行安装paddle的命令就成功了！
