I think there is need to add more details:

• What Python is used
• What system is used
• What environment is used
• What version of dpctl is used
• What type of environment is used (conda, pure pip, no virtual env)
• Versions on packages in environment

dpctl from master branch.

[diptorupd]

@oleksandr-pavlyk is this related to dpctl not providing a requirements.txt?

[PokhodenkoSA]

is this related to dpctl not providing a requirements.txt?

No.

[Vyacheslav-Smirnov]

Maybe just need to add cython in install_requires?

[oleksandr-pavlyk]

pip install -e . has been working for a while. For example, see #1660
