iniciando um serviço resulta em erro 'Tempo de espera do serviço' - não é possível localizar o caminho do python

Question

Quando eu inicio o serviço e verifico imediatamente o status sudo systemctl status myservice ele parece estar ativo e começa a funcionar, mas depois de alguns segundos ele muda para Failed to start service e mostra

 Failed with result exit code
 Service hold-off time over sheduling restart
 Stopped service
 Start request repeated too quickly
 Failed to start service

O arquivo:

[Unit]
Description=myservice

[Service]
ExecStart=/bin/sh /opt/df/run.sh -pidfile=/var/run/myservice.pid
Restart=always
RestartSec=60                       
SyslogIdentifier=myservice

[Install]
WantedBy=multi-user.target

Uma coisa que vem em mente é que, para que o script comece a ser executado (o run.sh em / opt / df), ele precisa de cerca de um minuto ou mais.

Não tenho certeza se isso tem a ver com esse problema.

------------ UPDATE ---------------

Hmm..Eu corro journalctl -xe e encontrei:

Activating virtualenv at .venv

Exception:

Se eu apenas executar o script (o run.sh sem serviço):

Activating virtualenv at .venv

Então, parece que o serviço não pode encontrar o caminho correto do python? (o caminho da anaconda que estou usando)
