Cannot read anaconda-mode server response

[nanounanue]

NOTE: I know that another issue (#360 ) has the same title, but apparently is a different error.

I am running GNU Emacs 27.0.50 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.12) of 2020-04-11, and anaconda-mode from melpa

anaconda-mode is configured as follows:

(use-package anaconda-mode
  :init
  (add-hook 'python-mode-hook 'anaconda-mode)
  (add-hook 'python-mode-hook 'anaconda-eldoc-mode)
  (add-hook 'python-mode-hook 'display-line-numbers-mode))

The *anaconda-mode* buffer displays:

anaconda_mode port 36723

and the anaconda-response shows

# status: (:error (error connection-failed deleted
 :host 127.0.0.1 :service 36723) :error (error connection-failed failed with code 110
 :host 127.0.0.1 :service 36723))
# point: 1

I am editing local files, inside a virtualenv What I am doing wrong?

The variable anaconda-mode-server-command contains the script that is run. It takes 3 CLI arguments. These would be ~/emacs.d/anaconda-mode/0.1.13 127.0.0.1 "" if you are using the defaults on local files. See if you can run the script to start the server on the command line (you will need to copy it to a file).

How are those arguments created?

I forgot to mention but I am using pyenv and the installation of anaconda-mode is handled by straight.el

[CeleritasCelery]

They are created here

anaconda-mode/anaconda-mode.el

Lines 390 to 396 in 6094ded

	:args `("-c"
	,anaconda-mode-server-command
	,(anaconda-mode-server-directory)
	,(if (pythonic-remote-p)
	"0.0.0.0"
	anaconda-mode-localhost-address)
	,(or python-shell-virtualenv-root ""))))

@nanounanue did you find a solution for this? I am experiencing very similar behavior. Weirdly, anaconda-mode seems to be working initially when I start up emacs, but stops working soon after with a similar message in the *anaconda-response* buffer:

# status: (:error (error connection-failed deleted
 :host 127.0.0.1 :service 44197) :error (error connection-failed failed with code 110
 :host 127.0.0.1 :service 44197))
# point: 1

I am also working on local files with a virtualenv activated through pyvenv, on emacs 27.1 and python 3.7.5.

Unfortunately this problem is persisting for me, and I haven't been able to figure out what is causing it. Are there any ideas on how to debug this? Also, could someone point me to the best way to restart the anaconda server without having to restart emacs altogether? That way, I could at least make it work again once the error message pops up. Thank you!

I get this error when I try to use anaconda-mode on a remote, tramp file. Is some setup required on the remote side?

# status: (:error (error connection-failed deleted
 :host 127.0.0.1 :service 38525) :error (error connection-failed failed with code 61
 :host 127.0.0.1 :service 38525))
# point: 1

BTW, I am happy just to get dabbrev completions when anaconda fails, but I lose everything.
