wp.init() crash with error of Could not find module '<..>warp.dll' (or one of its dependencies)

Hi!

I've installed warp with pip: pip install warp-lang. After I try to execute

import warp as wp
wp.init()

I get a FileNotFoundError:

Traceback (most recent call last):
  File ".\examples\example_sim_ant.py", line 26, in <module>
    wp.init()
  File "C:\Users\mariako\anaconda3\envs\warp\lib\site-packages\warp\context.py", line 2173, in init
    runtime = Runtime()

    dll = ctypes.CDLL(dll_path, winmode=0)
  File "C:\Users\mariako\anaconda3\envs\warp\lib\ctypes\__init__.py", line 373, in __init__
    self._handle = _dlopen(self._name, mode)
FileNotFoundError: Could not find module 'C:\Users\mariako\anaconda3\envs\warp\Lib\site-packages\warp\bin\warp.dll' (or one of its dependencies). Try using the full path with constructor syntax.

However, the dll file is on it's place

I checked warp.dll dependencies with https://github.com/lucasg/Dependencies tool, and some entries looks suspicious

However, I'm sure what to do from here. May I ask to take a look

I'm using Windows 11, python 3.8 in conda environment

Hmm, yes we have had a few issues with NVRTC not being found correctly on some user machines. We will soon switch to static linking this library to avoid these problems, but in the meantime it could make sense to check if another CUDA package is conflicting. @nvlukasz do you have any tips to debug this?

[maria-korosteleva]

@mmacklin Thank you! I would appreciate extra debugging tips

What is the ETA of the switch to static linking, if you are ok with disclosing this information, of course?

The problem does not reproduce in v0.7.2 🙂
