網狀 python 無法識別本地 python：錯誤：找不到 Python 共享庫，未加載 Python 綁定

Question

I have downloaded the python tar and extracted locally in linux ubuntu /app folder, When I configure this python using the R reticulate I get the error message " Error: Python shared library not found, Python bindings not loaded. Use reticulate::install_miniconda( ) 如果你想安裝 Miniconda Python 環境。”

這是我在 R 上運行的代碼

> Python_Script_version<<-paste0("/app/bin/Python-3.9.1")
> Sys.setenv(RETICULATE_PYTHON= Python_Script_version)
> reticulate ::use_python(Python_Script_version, required = TRUE)

> Sys.which("python")
                               python 
"/app/bin/Python-3.9.1/python" 

> library(reticulate)
> py_config()
Error in py_config() : could not find function "py_config"
> reticulate::py_config()
Error: Python shared library not found, Python bindings not loaded.
Use reticulate::install_miniconda() if you'd like to install a Miniconda Python environment.

感謝您的時間和回復。

您需要將 python 文件解壓縮到與 python 和 r 腳本相同的目錄中
