neotest.py not found

[Awallace3]

I have recently installed neotest with Lazy, and I am running into the following error when trying to run pytest:

neotest-python: .../packer/start/neotest-python/lua/neotest-python/init.lua:13: neotest.py not found

Is there something else that I need to install to have neotest.py? I tried looking at this pypi package (https://pypi.org/project/neotest/) but it didn't help.

return {
  "nvim-neotest/neotest",
  dependencies = {
    "nvim-lua/plenary.nvim",
    "antoinemadec/FixCursorHold.nvim",
    "nvim-treesitter/nvim-treesitter"
  },
  init = function()
    local nt = require("neotest")

    nt.setup({
        adapters = {
            require("neotest-python")({
                dap = {justMyCode = true},
                args = {"--log-level", "DEBUG"},
                runner = "pytest",
            })
        },
