Demucs No-Longer Installable via PIP Since Python 3.10 #286

Enverex · 2022-01-30T19:06:46Z

🐛 Bug Report

I don't think I'm doing anything stupid here. Demucs worked fine with Python 3.9 and happily installed via PIP. But since Python 3.10 came out, it doesn't appear to work via PIP anymore.

To Reproduce

Run "python -m pip install -U demucs" or "pip install demucs"

Expected behavior

To get the usual PIP installation progress bars, messages and for it to install with dependencies.

Actual Behavior

A lot of errors:

Can you try the following:

python -m pip install --use-deprecated legacy-resolver demucs

Enverex · 2022-01-30T21:25:35Z

That gets much further... but now fails on a dependency.

See chrisstaite/lameenc#15

Temporary fix would be to use Anaconda to get python3.9. Building locally lameenc is another possiblity.

adefossez · 2022-02-03T14:50:35Z

there should be lameenc available now, can you give it another go ?

Trying without legacy now does work, but again fails on another dependency. "dora_search" this time it seems:

I logged a ticket there (facebookresearch/dora#18) then realised you're a contributor of that repo so that was probably redundant, lol.

adefossez · 2022-02-04T11:43:00Z

The core issue is actually that torch is not available on python 3.10 at the moment, pip install torch fails for me.

Honestly for deep learning tools, you shouldn't expect being able to use bleeding edge versions of Python. It always takes a bit of time for all the frameworks to adapt, and I know I personally stopped at 3.8 to avoid running into those issues. Things like Google Colab are typically running quite old versions of Python (e.g. 3.8) and sticking to that one means I'm sure I can ship to Colab easily.

adefossez · 2022-02-14T11:19:09Z

See PyTorch task: pytorch/pytorch#66424 (comment)

Marviel · 2022-10-25T23:28:35Z

Unfortunately even when running with python 3.9 inside Docker on a Mac M1, this is still happening.

I believe this is also an issue with running Demucs in a Docker container on Mac M1 machines , because lameenc does not have an arm version deployed for linux

I could also have traced my errors wrong. It doesn't appear that pytorch has an arm64 build available on linux either so....

IvanIVGrozny · 2023-03-06T11:45:34Z

I found a way to get demucs to install on Python 3.10 and 3.11

First, install FFmpeg:

python -m pip install ffmpeg

Then, install pytorch this way:

CPU: python -m pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/test/cpu
CUDA 11.7: python -m pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/test/cu117
CUDA 11.8: python -m pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/test/cu118
ROCM 5.4: python -m pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/test/rocm5.4/

Next, install SoundFile:

python -m pip install soundfile

EDIT: forgot to mention you have to install Sox on Linux instead of SoundFile:

python -m pip install sox

Finally, install demucs this way: (thank you @adefossez)

python -m pip install --use-deprecated legacy-resolver demucs

Everything should be installed and working fine. @Ma5onic can this be added to README.md?

FelixNgFender · 2023-08-14T11:44:55Z

For those using Poetry and WSL2 (Ubuntu):

FFmpeg:

poetry add ffmpeg

CUDA 11.8:

poetry source add --priority=explicit pytorch-gpu-src https://download.pytorch.org/whl/test/cu118

poetry add --source pytorch-gpu-src torch torchvision torchaudio

Sox:

poetry add sox

Demucs:

poetry add demucs

This works wonderfully, the GPU utilization always reaches 100% during separation.

CarlGao4 · 2023-08-14T12:08:52Z

(Hasn't this issue been fixed?)

FelixNgFender · 2023-08-14T12:18:34Z

When I install demucs without any prior installations in a fresh virtual environment (WSL2, Ubuntu), it throws ValueError: libcublas.so.*[0-9] not found in the system path [a list of Python paths]

MatiasRizzi · 2023-12-28T15:17:28Z

poetry source add --priority=explicit pytorch-gpu-src https://download.pytorch.org/whl/test/cu118

poetry add --source pytorch-gpu-src torch torchvision torchaudio

when run command, I have bug:
[BUG] not torch (==2.2.0) is not satisfied.

CarlGao4 · 2023-12-29T03:45:47Z

Can you install with PIP?

FelixNgFender · 2023-12-29T04:09:28Z

PIP should work normally last time I checked. In other words, if you are using Poetry, install all other dependencies normally. For torch, torchvision, and torchaudio, use the instructions specified at https://pytorch.org/get-started/locally/ for your platform.

This is not the correct way to install torch. torch is going to release 2.2.0, which is not and also will probably not supported, so you'd better follow the instructions at https://pytorch.org/get-started/previous-versions/#v211

Follow this instructions for cuda 11.8 and run the poetry correctly.

poetry add  torch==2.1.1 torchvision==0.16.1 torchaudio==2.1.1

Use python 3.11.6 version.
Thanks
