Error in 'mamba env update'

[r530044129]

When I prepared the env, I met this error:

Here is window, does this cmd only support linux?

Hi @r530044129 .
You're right, the mamba env update command only supports Linux for now. Our official installation instructions are tailored for Linux but we're working hard on adding more documentations about dependencies. In the future we might introduce new systems for managing dependencies.

On the other hand, our dependency demands are very loose and I do personally use a Windows machine for the viewer. The only core requirement is pytorch, thus you can try installing pytorch following their official instruction in any way. After this you might want to install missing packages if it's related to the algorithm or module you want to run.

For example, if you're using the real-time viewer, opengl-related packages should be installed:

glfw
PyGLM
pyperclip
pyopengl
imgui-bundle
opencv-python
cuda-python
pdbr

Use the command evc-gui to test your GUI installation.
You might see warnings about missing imports from some specific modules but they can be ignored as long as they don't interfere with your usage. (for example, pytorch3d)

Hi @lixiangweiabc , I updated the installation guide to include more description about Windows. Could you please check whether it's easier to follow now?

Hi，thanks for your updating. For issue https://github.com/zju3dv/4K4D/issues/14#issue-2067001433, I founde that the nvidia-driver and the cuda version is incompatible. For some reason, I can't update the Nvidia driver version of my current machine. I will follow your guide in a new ubuntu 18.04 machine.
