Can you try: omni_python -m pip install opencv-python?

[Tranthanhbao198]

Can you try: omni_python -m pip install opencv-python?
CMake Error at CMakeLists.txt:32 (find_package):
By not providing "FindTorch.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Torch", but
CMake did not find one.

Could not find a package configuration file provided by "Torch" with any of
the following names:

TorchConfig.cmake
torch-config.cmake

Add the installation prefix of "Torch" to CMAKE_PREFIX_PATH or set
"Torch_DIR" to a directory containing one of the above files. If "Torch"
provides a separate development package or SDK, be sure it has been
installed.

hello, i am reinstalling, but at step8, i got this error, can you help me?

and this error

Can you try: omni_python -m pip install opencv-python?

yes thank you it worked

@balakumar-s bala
please help me to fix them. thank you so much

[balakumar-s]

Is it possible for you to use the provided docker?

[balakumar-s]

In addition, python version in conda should match isaac sim python version of 3.8.

Also, check your cuda version. It should be 11.8.

Hello, i dont have many experiment with docker@.@

[Tranthanhbao198]

How do I know version of python isaacsim? Because I don't see any information about it before? Please let me know.
And, I read docs and it said that I should install cuda11.7, so I should need to reinstall it?
Thank you so much.
