Introduction

Running Habitat Sim and Habitat Lab without a GPU can be a challenging task, especially for those who are new to the field of robotics and simulation. However, with the right steps and knowledge, it is possible to run these simulations without a GPU. In this article, we will guide you through the exact steps required to run Habitat Sim and Habitat Lab without a GPU.

Understanding the Error Message

Before we dive into the solution, let's first understand the error message that you are encountering. The error message Platform::WindowlessEglApplication::tryCreateContext(): unable to find CUDA device 0 among 2 EGL devices in total indicates that the system is unable to find a CUDA device (i.e., a GPU) to use for the simulation. This is because Habitat Sim and Habitat Lab are designed to run on a GPU, and without one, the system will not be able to create a context.

Prerequisites

Before we begin, make sure that you have the following prerequisites:

  • A Ubuntu 18.04 Virtual Machine (or a similar Linux distribution)
  • Habitat Sim and Habitat Lab installed on your system
  • A CPU that supports AVX2 instructions (required for Habitat Sim and Habitat Lab)

Step 1: Install the Required Packages

To run Habitat Sim and Habitat Lab without a GPU, you will need to install the following packages:

  • libegl1-mesa (for EGL support)
  • libgles2-mesa (for GLES support)
  • libgles3-mesa (for GLES3 support)
  • libegl-mesa0 (for EGL support)

You can install these packages using the following command:

sudo apt-get install libegl1-mesa libgles2-mesa libgles3-mesa libegl-mesa0

Step 2: Configure the Environment Variables

To run Habitat Sim and Habitat Lab without a GPU, you will need to configure the environment variables to use the CPU instead of the GPU. You can do this by setting the following environment variables:

  • HABITAT_SIM_CPU_ONLY=1 (to enable CPU-only mode)
  • HABITAT_SIM_EGL_DEVICE=0 (to specify the EGL device to use)

You can set these environment variables using the following command:

export HABITAT_SIM_CPU_ONLY=1
export HABITAT_SIM_EGL_DEVICE=0

Step 3: Run the Simulation

Once you have installed the required packages and configured the environment variables, you can run the simulation using the following command:

habitat-sim --cpu-only --egl-device 0

This will run the simulation using the CPU instead of the GPU.

Step 4: Verify the Results

To verify that the simulation is running correctly, you can check the output of the simulation. You can do this by running the following command:

habitat-sim --cpu-only --egl-device 0 --verbose

This will run the simulation in verbose mode, which will output the simulation results to the console.

Conclusion

In this article, we have shown you how to run Habitat Sim and Habitat Lab without a GPU. By following the steps outlined above, you should be able to run these simulations on your CPU instead of your GPU. We hope that this article has been helpful in guiding you through the process of running Habitat Sim and Habitat Lab without a GPU.
