On windows, in conda, to run the visualize_data.py I’m receiving `no module: l5kit.data` about l5kit HOT 10 CLOSED

Hi @Shreyagupta21, I'm assuming the import error is not related to l5kit.data only but l5kit in general (meaning you would get the same also by trying something like from l5kit.dataset.dataloader_builder import build_dataloader), please correct me if that's note the case though.

Can you attach here the output of pip freeze maybe? That should tell us a little bit more about your python environment

from l5kit.

Interesting, l5kit is installed in your env (in editable mode) so it should be available as a package.

I sadly can't reproduce the error under linux using pip in a virtualenv. The error could be due to:

• using conda; I'm positive we tried it under Windows, but it may be worth trying using only venv and pip still;
• Windows itself. I'm assigning this to @oliver-scheel who has a working L5Kit build under Windows

I did the pip install -r requirements.txt removing torch and torch vision and tried pip install -e l5kit
Is there something I’m missing?

Just noticed the additional pip install -e l5kit. pip install -r requirements.txt should already install also l5kit in editable mode (didn't change the outcome under Linux though)

from l5kit.

Also @Shreyagupta21 , is visualiza_data.py something you wrote or are you referring to the notebook we ship? Are you running it from its folder (examples) or from somewhere else?

from l5kit.

Hello @lucabergamini, Visualize_data.py is the notebook you ship and I'm running it from the examples folder.

from l5kit.

Any chance you can try a fresh env with pip only (no conda)? Can you also paste here the full error stack please?

I'm sorry but I can't be of much help on Windows sadly :(

from l5kit.

I tried a fresh env with pip, but unfortunately it didn't work. This is the full error stack:

ModuleNotFoundError Traceback (most recent call last)

3 import numpy as np

6 from l5kit.dataset import EgoDataset, AgentDataset
7

ModuleNotFoundError: No module named 'l5kit'

from l5kit.

Hi @Shreyagupta21, thanks for waiting, and sorry about the late reply!
As @lucabergamini said, we mainly develop under Linux, so it took me a while to get a Windows machine running.
But now I have, and am very happy to help you.
Although I have to say, 'unfortunately' for me everything works under Windows - and I am a bit out of guesses here, as pip freeze shows you have l5kit installed ...
Could you tell me more about your system? What Windows is it, do you have a CUDA compatible GPU? which version of Pytorch did you install and how, which python?
Similar to you, I created a new condas environment, installed Pytorch manually and then ran our installer. works.
could you try one more time for me setting up a new condas environment and installing our latest l5kit version? Then, please run python in that activated environment and simply try the line 'from l5kit.data import ChunkedStateDataset, LocalDataManager' - does this already raise the same error (excluding any possible issues with our visualizer example, but I would be amazed if that changed anything).

from l5kit.

Hello @oliver-scheel. I ended up just switching Linux which solved all my issues. Thanks for trying to help me.

from l5kit.

Hi @Shreyagupta21 , happy to hear it's working now - hope you enjoy working with L5Kit and please let us there about any further issues!
