How to automatically use a conda environment?

[spring-haru]

I am trying to automatically set a conda environment if a .py file is opened. I wonder if you can help me out. I tried the following

return  {
  "HallerPatrick/py_lsp.nvim",
  config = function()
    require('py_lsp').setup{
      opts = {
        host_python = "~/opt/anaconda3/envs/py12/bin",
        auto_source = true,
        language_server = "pyright",
        source_strategies = "conda",   -- "default", "poetry", "conda", "system",
        default_venv_name = "py12"
      }
    }
  end,
}

but it returns

Could not retrieve python path, try :PyLspReloadVenv

Then, if I do :PyLspActivateCondaEnv, then the cond environment is used in lsp, though :checkhealth shows

py_lsp: require("py_lsp.health").check()

py_lsp.nvim Report ~
- ERROR No client attached
- ERROR Setup is incorrect

How am I supposed to change the code to automatically set the conda environment. Thanks in advance.

Hey! First try to use a table instead of a string for the source strategy, so:

return  {
  "HallerPatrick/py_lsp.nvim",
  config = function()
    require('py_lsp').setup{
      opts = {
        host_python = "~/opt/anaconda3/envs/py12/bin",
        auto_source = true,
        language_server = "pyright",
        source_strategies = { "conda" },
        default_venv_name = "py12"
      }
    }
  end,
}

If that not works, could you please check what conda env list --json returns for you?

I also pushed some changes so you might want to update this plugin

Thanks. I updated the plugin and used a table for the source strategies, but basically no change. Let me summarize what I got:

• Opening a .py file still shows

Could not retrieve python path, try :PyLspReloadVenv

• Then, doing :PyLspActivateCondaEnv shows

Using Python Virtual Environment: /Users/my_name/opt/anaconda3/bin/python

• :checkhealth shows that the conda environment is correctly set for lsp, but it also shows

py_lsp: require("py_lsp.health").check()
py_lsp.nvim Report
- ERROR No client attached
- ERROR Setup is incorrect

where the last line sometimes (seemingly randomly) changes to

- OK Setup is correct

And conda env list --json shows

{
  "envs": [
    "/Users/my_name/.julia/conda/3/aarch64",
    "/Users/my_name/.julia/environments/v1.9/.CondaPkg/env",
    "/Users/my_name/Library/jupyterlab-desktop/jlab_server",
    "/Users/my_name/opt/anaconda3",
    "/Users/my_name/opt/anaconda3/envs/mercury",
    "/Users/my_name/opt/anaconda3/envs/numpy2",
    "/Users/my_name/opt/anaconda3/envs/otter5",
    "/Users/my_name/opt/anaconda3/envs/otter6",
    "/Users/my_name/opt/anaconda3/envs/py10",
    "/Users/my_name/opt/anaconda3/envs/py11",

  ]
}
