Echodoc does not show function signatures

[landge]

Hi,

I'm having problems getting echodoc to work with my setup.
Can anyone spot an obvious configuration issue?

Here's my neovim checkhealth:

`health#deoplete#check

deoplete.nvim

  and then create an issue on github

The completions are shown in a pop-up, but the signatures are not shown.

Nothing is shown after selecting the candidate with Ctrl-n, Ctrl-y

Thanks in advance,

I have tested it and it is expected behavior.
pandas.DataFrame is module and it doesn't have function prototype.
echodoc works for function prototype only.
Closing.

You can test os.access instead. It works for me.

Great, thank you!
