Cannot install Lerobot

[Prasit7]

I am getting an error when the installation is building the av wheel. It is not passing this part of the installation

[tuzhiLiu]

我直接运行cd ~/lerobot && pip install -e ".[feetech]"之后好像成功了

Please make sure you follow the recently updated instructions:

lerobot/README.md

Line 95 in 78fd1a1

Create a virtual environment with Python 3.10 and activate it, e.g. with [`miniconda`](https://docs.anaconda.com/free/miniconda/index.html):

For reference:

• fix(deps): constrain PyAV version to resolve OpenCV-python ffmpeg version conflict #883
• fix(docs): hot-fix updating installation instructions after #883 #907
• chore(docs): update docs #911

[imstevenpmwork]

Download our source code:

git clone https://github.com/huggingface/lerobot.git
cd lerobot

Create a virtual environment with Python 3.10 and activate it, e.g. with miniconda:

conda create -y -n lerobot python=3.10
conda activate lerobot

When using miniconda, if you don't have fffmpeg in your environment:

conda install ffmpeg

Install 🤗 LeRobot:

pip install --no-binary=av -e .

NOTE: If you encounter build errors, you may need to install additional dependencies (cmake, build-essential, and ffmpeg libs). On Linux, run:
sudo apt-get install cmake build-essential python-dev pkg-config libavformat-dev libavcodec-dev libavdevice-dev libavutil-dev libswscale-dev libswresample-dev libavfilter-dev pkg-config. For other systems, see: Compiling PyAV

Same issue here. I am using the updated instructions on Linux.

[sachaMorin]

Fixed by running conda install ffmpeg even if ffmpeg was already available on the base machine.

Did u run conda install ffmpeg right before running the installation?

[sachaMorin]

Yes!

Running into the same issue.
Installed ffmpeg as recommended and run pip install --no-binary=av -e .:

[amisev]

Thanks, I'm installing on Mac. I resolved an issue above ^^ by fixing PKG_CONFIG_PATH.
I got another one related to ffmpeg version, it turns out that PyAV 12.4.0 doesn't support ffmpeg 7 (see PyAV-Org/PyAV#1463 (comment)). Will try to downgrade ffmpeg.

[amisev]

brew install ffmpeg@6 helped

Hi,
I'm utilizing this thread to add some issue with the initial installation of av wheel. I'm getting this error :

This is a new one for me @Freeman656 Can you provide us more details? Can you share with us the output of the following commands?

uname -a
ffmpeg -version
ls /opt/homebrew/lib/libav* # for Mac
ldconfig -p | grep libav* # for Linux

In the virtual environment:

ffmpeg -version
pip freeze | grep torch
pip freeze | grep av

If you are in Windows, you will have to follow these instructions, although I haven't tested them: https://pyav.org/docs/develop/overview/installation.html#build-on-windows
Mind compiling the right version av>=12.0.5,<13.0.0.
