Issues:

These are general guidelines for opening productive issues. If you don't follow them, we can't help you.

Mandatory requirements:

Please be as detailed as possible.
- "It doesn't work" is not a helpful issue.
- Provide information about your environment:
  - What OS are you running (must be officially supported)
  - How did you install Pupy? I.e. Docker compose (standard way to install), virtualenv, or the pre-built Docker image?
  - What specific commit are you using? Did you pull the latest version of Pupy from the master branch before running it?
Please provide logs or detailed errors produced by the issue.
- You can provide screenshots, code snippets, logs created by the script <logfile> command, asciinema recordings, etc.
- For detailed information about how to correctly log output from these programs, see the logging section.
Edit your original post rather than creating multiple new ones in succession.
Use proper markdown formatting for code snippets with backticks.
- See the GitHub guide to Markdown.
For long code segments or logs, please create a gist and paste the link to it in the issue.
Ensure that you are using a supported operating system.
Before reporting an issue, please update your OS, pull the latest commit and verify that it is still an issue afterwards.

If possible, please use proper English grammar and spelling.
- If we cannot understand you, we cannot fix your problem.
If possible and convenient, please reproduce your issue in a freshly installed, fully updated VM. This VM must be a supported operating system.

Asciinema:
- To install: sudo pip3 install asciinema
- To record: asciinema rec -i 2 <output-file>.cast
- Run whichever commands are required to reproduce the issue.
- Type exit to stop the recording.
- To upload: asciinema upload <output-file>.cast
- Paste the resulting link into your issue.
Script:
- script <output-log-file>
- Run whichever commands are required to reproduce the issue.
- Type exit
- Copy the contents of the output file and create a gist.
- Paste that gist into your issue.
Strace:
- Run strace -ff -o <output-file> <program to run and arguments for it>

Please close the issue if it has been fixed or your question has been answered.
