It sounds like you're trying to run an application in Python and experiencing the `ModuleNotFoundError: No module named 'onnxruntime'` error. `onnxruntime` is a Python package. The error occurs because Python cannot find this package in its environment. Here's how you can fix it: 1. **Install the onnxruntime package**: You can install it using pip, Python's standard package installer. Open your terminal, and type the following command: ``` pip install onnxruntime ``` Optionally, if you're working within a conda environment, you might want to use conda to install packages. Here's how: ``` conda install -c conda-forge onnxruntime ``` 2. **Verify the installation**: After installation, you can verify it by trying to import the module in Python interpreter. Run: ```python import onnxruntime ``` If you see no error message, the installation was successful. Keep in mind: - Always ensure you're using the right Python environment, especially when working within virtual environments, conda environments, etc. Your package needs to be installed in the environment you're actually running. - Some packages may require specific versions of Python. If you continue to experience problems after installing `onnxruntime`, verify that your Python version is compatible with the package version you've installed. Please let me know if this helps or if you need assistance with something else.
