Dependency resolution is extremely slow #4924

alecandido · 2021-12-21T15:49:36Z

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

Issue

Just running poetry update took 15 minutes to do exactly nothing:

Updating dependencies
Resolving dependencies... (922.3s)

Writing lock file

No dependencies to install or update

Even more, for other packages with a few more dependencies, I've seen poetry running for more than one hour without completing (I killed).

In general, this behavior happens for all the sub-commands that potentially have to resolve dependencies, including add, update, but even install.

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

I'd assume that the issue is numpy here. Poetry has to check too many versions.

alecandido · 2021-12-24T07:56:01Z

Ok, I'm going to test, but for sure you have a point.

I'm not sure if I can pin the exact numpy version, since in a non-minimal example it's also a dependency of other dependencies...

alecandido · 2021-12-24T08:12:48Z

Nope, even without numpy is taking long.

Moreover, using -vvv and watching the logs (meaning me watching the terminal), at some points it's completely stuck:

Logs up to stack (same pyproject.toml without numpy)

More updates:

on the opposite of what someone guessed on Discord, I don't believe it's a lockfile problem, a new project with same dependencies resolves much faster (i.e. without lockfile) once the first one has been resolved
I guess than is somehow related to network fetching and cache
interestingly enough, sometimes if I kill the process and rerun, it advances a bit more; some other times instead, it blocks at a point where it was already stuck before, but that has been already passed in a former instance...

Writing lock file

jimmywan · 2021-12-27T18:37:43Z

Just tried this myself using 1.1.11 on @item4's pyproject.toml from above:

> poetry lock -vvv
...
1: Version solving took 10.174 seconds.
   1: Tried 1 solutions.

Dunno if it matters, but I have this in my env:
POETRY_VIRTUALENVS_CREATE=false

Just noticed you had 1.1.12, so I updated and retried:

> poetry self update 1.1.12
> rm poetry.lock
> poetry lock -vv
   1: Version solving took 0.146 seconds.

@jimmywan please, show even the pyproject.toml (or specify it is the same of mine).

Also, try to rerun after issuing

poetry cache clear pypi --all

to see the difference with and without cache.

jimmywan · 2021-12-28T17:26:34Z

@jimmywan please, show even the pyproject.toml (or specify it is the same of mine).

I've updated my comment above to reflect the fact that I ran that test using @item4 's pyproject.toml.
Apologies for any confusion.

Also, try to rerun ... to see the difference with and without cache.

Below I reran this on a cleared cache using your pyproject.toml. Finished in ~90s.

Thank you for your data. 90 seconds it's more similar (same scale) but much more reasonable, for a cache-less installation.

It's weird that apparently same tool in same conditions has such different results. Of course this means that the conditions are not the same, but it also yields that we are not controlling the very relevant differences.

I guess possible differences are:

poetry version: 1.1.11 @jimmywan, 1.1.12 me, 1.2.0a2 @item4
installation (maybe): for sure I installed with pipx, but I would say this shouldn't make any difference (but I don't know what is making the difference, so I put nevertheless)
network: apparently not very relevant known differences, but for sure we have different networks and we're geographically spread
a huge who knows...

jimmywan · 2021-12-30T15:05:00Z

I guess possible differences are:

poetry version: 1.1.11 @jimmywan, 1.1.12 me, 1.2.0a2 @item4

FYI, my last test was with 1.1.12.

maciejskorski · 2021-12-31T22:30:32Z

I checked this on the recent master, also works fine.

item4 · 2022-01-04T01:19:03Z

@maciejskorski how can i try with master branch? is it just can use with --preview flag installation?

alecandido · 2022-01-04T09:54:47Z

@item4 For sure you can download the repo and install from the source :)

alecandido · 2022-01-04T09:56:56Z

Keep taking a lot for me. Still on 1.1.12, even with weeks old cache, operations like:

poetry add
poetry add -D
poetry lock
poetry update

take hundreds of seconds, if not thousands.

item4 · 2022-01-16T01:09:42Z

In my case, I can fix with change DNS settings. I used poetry in WSL2, and WSL2 change /etc/resolv.conf in random time and it occurs DNS resolving problem. So I add disable config for WSL2 DNS method and make /etc/resolv.conf by my hands.

Added django to my very first brand new Poetry project and it took almost 1.5 hours to resolve. The "Creating virtualenv" step was also somewhere between 15 and 30 minutes. Finally the installing step took about 20 minutes.

$ poetry new <my_project>
Created package <my_project> in <my_project>
$ poetry add django

I don't know much about the PyPI API, but it seems that poetry is querying package versions one-by-one. Isn't it possible to query all versions that satisfy a dependency and store them in a chache? If the API allows that it'd significantly reduce the number of network requests to PyPI which -vvv seems to indicate takes the longest.

If the API allows that it'd significantly reduce the number of network requests to PyPI which -vvv seems to indicate takes the longest.

This might be relevant, but I wonder if it's really the bottleneck: even pip has to resolve dependencies for installation (maybe/likely with less effort than poetry), and also dependencies of dependencies, and so on, but it's not taking the same amount of time.
So, for sure networking is always a good candidate for slow-down, but I'm still not convinced is our best candidate for 2h poetry update...

Mithrandir2k18 · 2022-01-27T18:45:50Z

May it hits some individual API-query limits that forces a wait period?

P.S.: If the api docs on rate limits is up-to-date then this doesn't seem to be a candidate for the issue(besides overall networking overhead).

john-sandall · 2022-02-19T11:04:04Z

For those hitting this, I added a couple tips on this issue on how to improve issues with Poetry being slow: #2094 (comment)

alecandido · 2022-02-19T11:24:16Z

Thank you @john-sandall for your advice, unfortunately I've always been on Ubuntu with a download speed >= 500 Mbit/s, and mostly not so many packages.

So, the amount of time it's time unexplained for me, but at least I got a reference to an older and still open issue, that I failed to found before (even though has practically my same title).

I'm tempted to close this as duplicated.

alecandido · 2022-02-20T17:59:01Z

Similar or duplicated of:

I believe the best contribution I can give is to close this one, keep tracking the others.

I suggest anyone that falls here to look instead to #2094, since it's the oldest one I'm aware of dealing with this issue.

ash1khan · 2022-06-18T17:02:43Z

It will take a thousand years to catch pipenv. Tried almost all workaround and installing in fresh linux with a fresh empty project. Adding fastapi took 4329.2 s. I don't know what poetry does extra for keeping dependency check for me. But I really don't care. All i care is about time. Creating virtual env with cementing lock file for dependencies with pipenv took 0.2 sec. I am out

alecandido · 2022-06-19T06:33:18Z

Taking long might be frustrating, and I really hope it will improve over time.

On the other hand this is not a frequent operation in development. So I just leave my computer doing it for me, while doing something else.

In any case, you got it for free @ash1khan, so I see no reason why to complaint with people here, that are only trying to improve. If anything, consider to take part to the effort.

Can poetry consider a pattern install without checking for dependencies

szandara · 2023-05-17T11:13:15Z

Resolving dependencies... (6779.1s) and counting.......

it helped me with Resolving dependencies... (millions seconds)

and then
poetry install

This might work for you if you are working on any modern Linux-based distro. It's pretty easy to try.

TDLR: Issues as IPv6 resolution is preferred over IPv4.
Easy workaround to test: Disable IPv6, test and confirm if this solve your issues

# Check if IPv6 is enabled in your system (0 Means Enable, 1 Means disable)
sysctl -a 2>/dev/null | grep disable_ipv6 

# Disable IPv6
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1 
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=1

# Test
poetry install

# Re-enable IPv6
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=0
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=0
sudo sysctl -w net.ipv6.conf.lo.disable_ipv6=0

This solved my issues with Poetry and PIP being extremely slow to install packages.

I've written a more extensive post on this workaround. Have a look if you want to get more information.
