Error on running moonshot backtest: FileNotFoundError: [Errno 2] No such file or directory: ‘/codeload/moonshot/__init__.py’

Technical Help
#1

hi
docker-compose.yml is configured to load GitHub - quantrocket-llc/codeload-demo: Demo configuration files and strategy code for QuantRocket'.
the docker-compose section is shown below:
when I run;
quantrocket moonshot backtest 'umd-demo' --outfile umd_moonshoot.pdf
strategy defined in up_minus_dowm.py
I get the following error (full flightlog stack dump below)
FileNotFoundError: [Errno 2] No such file or directory: '/codeload/moonshot/init.py'
I tried creating an empty init.py file in the c:\users\darryl\quantrocket\codeload\moonshot directory.
but it did not help.
Any help why I am getting this error would be appreciated
thanks
darryl

Bug in moonshot when importing pyfinance module
#2

It seems like your moonshot container doesn't have access to the codeload volume. Make sure your moonshot config includes the volumes_from key:

  moonshot:
    image: 'quantrocket/moonshot:0.1.4'
    volumes_from:
      - codeload
#3

this is the extract from my docker-compose.yml file it look ok:

moonshot:
image: 'quantrocket/moonshot:0.1.4'
volumes_from:
- codeload
restart: always

#4

You might want to redeploy moonshot to make sure:

docker-compose -p quantrocket up -d --force-recreate moonshot

You can then poke around the moonshot container and list the directory to make sure you see your code files in there to double check:

docker exec -ti quantrocket_moonshot_1 bash
$ ls /codeload

Should look the same as what's in /c/users/darryl/quantrocket/codeload

thanks
redeploying moonshot fixed the problem
