1. Before I’d installed codejail sandbox by instructions from [https://docs.bitnami.com/installer/apps/edx/configuration/sandbox-codejail](https://docs.bitnami.com/installer/apps/edx/configuration/sandbox-codejail).  
Also I talked about the problem with bitnami support in end of topic: [https://community.bitnami.com/t/unable-to-deliver-your-submission-to-grader-reason-queue-edx-demox-not-found-please-try-again-later/72080/5](https://community.bitnami.com/t/unable-to-deliver-your-submission-to-grader-reason-queue-edx-demox-not-found-please-try-again-later/72080/5). They just closed it, and wrote me, that on this forum I should ask about codejail.  
But I’d found instruction: [https://github.com/edx/codeja](https://github.com/edx/codeja)
2. In directory edx\_installdir/apps/edx/venvs/edxapp/src/codejail I’d found codejail
3. As wrote on page [https://github.com/edx/codejail](https://github.com/edx/codejail), I’ve activated command edx\_installdir/use\_edx
4. By the same instruction, I’d run python. And wrote next:  
import codejail.jail\_code  
codejail.jail\_code.configure(‘python’, ‘/bin/python’)  
import codejail.safe\_exec  
codejail.safe\_exec.safe\_exec(“a=5”, {})
5. As result I have an error. An info about the error is on a screenshoot: [https://drive.google.com/open?id=1Q0\_-uLlex3MnZWHhQ9YGUHVc-SIB2L0K](https://drive.google.com/open?id=1Q0_-uLlex3MnZWHhQ9YGUHVc-SIB2L0K)

@Edx_Email.2 It looks as though you’ve specified a binary that doesn’t exist.

Is `/bin/python` a binary on your system?  
Most systems I’ve seen have python installed in `/usr/bin/python`.

You can find your python installation location by running `type -P python`.  
Try configuring codejail with that path instead of `/bin/python`

No, I’ve specified true binary.  
I’ve tried and “/usr/bin/python”, and “edx\_directory/apps/edx/venvs/edxapp-sandbox/bin/python”
