サービスを開始すると、「サービスの遅延時間が切れました。」エラーが発生します。 Pythonパスが見つかりません

サービスを開始してすぐにステータスを確認すると、sudo systemctl status myservice有効になっているように見え、実行が開始されます。数秒後にに移動してFailed to start service表示されます。

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

文書：

[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

1つの注意点は、スクリプトの実行（/opt/dfのrun.sh）を開始するのに約1分以上かかることです。

これが問題に関連しているかどうかはわかりません。

うーん..走ってjournalctl -xe発見したもの：

スクリプトを実行した場合（サービスなしでrun.sh）：

Activating virtualenv at .venv
Ignoring indexes: https://pypi.python.org/simple
Requirement already up-to-date: pip==8.0.2+gx2 in ~/.local/lib/python2.7/site-packages

Requirement already satisfied (use --upgrade to upgrade): SQLAlchemy==1.0.8 in ~/anaconda2/lib/python2.7/site-packages (from -r requirements.txt (line 5))
....

その場合、サービスは正しいPythonパスを見つけることができないようです。 （私が使用するアナコンダパス）？
