Can not import packages installed in server_directory when using docker

Problem

If I connect to a docker container with jedi already installed, Python will ignore the jedi installed in server_directory, but import the one installed default.

Reproduce the problem

Related Emacs configuration

(use-package anaconda-mode
  :hook ((python-mode . anaconda-mode)
         (python-mode . anaconda-eldoc-mode)))

(use-package docker-tramp
  :config
  (progn
    (add-to-list 'tramp-remote-path 'tramp-own-remote-path)))

Steps

Run docker run -i -t pytorch/pytorch:1.9.0-cuda11.1-cudnn8-runtime bash and install socat.
Start Emacs, and C-x C-f /docker:root@{container-id}:{path_to_a_python_file}

The *anaconda-mode* buffer shows:

Specifications

Host machine:

OS: Manjaro 21.1.5 Pahvo
Kernel: x86_64 Linux 5.10.70-1-MANJARO
docker 1:20.10.8-1
anaconda-mode 20210409.1536
docker-tramp 20210729.508

Docker container:

which conda gives /opt/conda/bin/conda
which python gives /opt/conda/bin/python
conda list jedi gives version 0.17.0

ls /root/.emacs.d/anaconda-mode/0.1.14-py3/ shows

jedi                   parso                  service_factory
jedi-0.18.0.dist-info  parso-0.8.2.dist-info  service_factory-0.1.6.dist-info

Thus we can know that anaconda-mode is using the pre-installed jedi instead of the one installed in ${HOME}/.emacs.d/anaconda-mode/.

Does #416 fix this for you?

The code below in anaconda-mode.py cause the server_directory to be add to the end of sys.path. Thus it has has a lower priority and is ignored.

anaconda-mode/anaconda-mode.py

Line 36 in 4f367c7

site.addsitedir(server_directory)

One workaround is that

@@ -34,6 +34,7 @@
 if not os.path.exists(server_directory):
     os.makedirs(server_directory)
 site.addsitedir(server_directory)
+sys.path.insert(0, sys.path.pop(-1))

Does #416 fix this for you?

Thank you! I just saw your reply. #416 does the same thing as my workaround.

I just pushed a commit that should fix it then.
Please test and close this issue if it's working.
Thanks for the detailed bug report.

Fixed in 0546c09.
