Poetry cannot install flash-attention #8427

Atry · 2023-09-10T19:45:08Z

Poetry version: 1.6.1
Python version: 3.10.12
OS version and name: NixOS unstable
pyproject.toml:

name = "poetry-bug-report"
version = "0.1.0"
description = ""
authors = ["Your Name <you@example.com>"]
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.10"
flash-attn = "2.2.1"


[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

I am on the latest stable Poetry version, installed using a recommended method.
I have searched the issues of this repo and believe that this is not a duplicate.
I have consulted the FAQ and blog for any relevant entries or release notes.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

$ poetry install -vvv

Note: This error originates from the build backend, and is likely not a problem with poetry but with flash-attn (2.2.1) not supporting PEP 517 builds. You can verify this by running 'pip wheel --use-pep517 "flash-attn (==2.2.1)"'.

Issue

Note that flash-attention requires --no-build-isolation according to their document https://pypi.org/project/flash-attn/#:~:text=install%20flash%2Dattn-,%2D%2Dno%2Dbuild%2Disolation,-Alternatively%20you%20can

However, poetry does not support --no-build-isolation.

As a workaround to poetry install, the following command works

PIP_NO_BUILD_ISOLATION=1 pip install -e .

The text was updated successfully, but these errors were encountered:

flash-attention does not use PEP 517 because:

We tried this earlier (v1.0.4 to 1.0.8 i think) and it was a lot of headache because the torch requirement conflicts with different ways that people install pytorch in their system.

If they don't support PEP 517 API, then there is nothing Poetry can do, since we only support PEP 517. You have to use other tools to manage your project.

then there is nothing Poetry can do, since we only support PEP 517.

The claim seems false, because the poetry managed project can indeed install flash attention with the following command

cd poetry-bug-report && PIP_NO_BUILD_ISOLATION=1 pip install -e .

On the other hand, the following command fails

cd poetry-bug-report && PIP_NO_BUILD_ISOLATION=1 poetry install

Since both pip install and poetry install internally use poetry-core, the behavior difference is unexpected.
