使用 conda 在 cron 上运行 python 脚本

Question

Trying to send some output to Slack using cron on an instance of GCP Compute Engine running Linux Ubuntu 18.04.2 LTS .

Output is generated by python script.

Python script is usually run using conda activate my_env and python my_script.py

I have made the bash file executable by doing chmod +x my_script.bash

Here is content of bash file:

#!/bin/bash
source /home/user/miniconda3/bin/activate
conda activate my_env
python /home/user/folder/cron/reports.py -r check_stocks

I would expect adding the following line to crontab -e :

00 21 * * * cd /home/user/folder/cron/ && /bin/bash my_script.bash would give me the same results.

I run cd /home/user/folder/cron/ && /bin/bash my_script.bash in my shell and the script runs fine.

Answer 1

Make your .py file exacutable too ( chmod +x file.py ) - otherwise it won't work. You can find similar issue resolved here .

Answer 2

I had a similar issue and I gave up activating the conda environment and instead called directly the python bin in the miniconda environment folder, like this:

00 21 * * * /home/myuser/miniconda3/envs/my_env/bin/python /home/user/folder/cron/reports.py

I don't think this is the recommended solution, especially if you have a complex project with dependencies and you are importing a lot of modules, but for my simple script it solved the problem.
