Hello, I experienced this problem in installing this package. I am not sure how to resolve it.
`> library(flaiR)
flaiR: An R Wrapper for Accessing Flair NLP Tagging Features
Python : ✗
Flair: ✗
Flair is installing from Python
Error: 套件或命名空間載入失敗 ‘flaiR’:
attachNamespace() 裡算 'flaiR' 時 .onAttach 失敗了，詳細內容：
呼叫: stop_no_virtualenv_starter(version)
錯誤: Suitable Python installation for creating a venv not found.
Please install Python with one of following methods:

• https://www.python.org/downloads/
• reticulate::install_python(version = '')
  In addition: Warning message:
  R graphics engine version 16 is not supported by this version of RStudio. The Plots tab will be disabled until a newer version of RStudio is installed. `

Thank you for your @joufeihuang .
I believe you've successfully downloaded it. From what I can tell, you've installed Python. However, I suspect your Python version might need to be 3.7 or higher. Otherwise, the Python Flair NLP may not automatically integrate when you load the flaiR package in R.

There are a few steps you can take:

1. update Python to 3.7. Then, you can directly use the reticulate package in R to install the Flair Python library. Use the following commands:

library(reticulate)
# This will tell you where Python is installed. py_config() 
# Activate the Python environment.
reticulate::use_python(reticulate::py_config()$python) 
# Install the Flair library in the specified Python environment.
reticulate::py_install("flair") 

After that, reload the flaiR package in R again.
Hope it works

Hi, after re-installing Python on my Windows PC, the flaiR installation via GitHub repo went straightforward. No issues at all!
When re-installing Python, make sure to add Python to the path.
Cool work!
