libmkl_rt.so.1: cannot open shared object file: No such file or directory

This error typically occurs when the system is unable to find the shared library file libmkl_rt.so.1. This library is associated with Intel Math Kernel Library (MKL), which is used for high-performance mathematical computations.

To resolve this issue, you can try the following steps:

1. Check if the library file is present on your system. You can use the `find` command to search for it:

   find / -name libmkl_rt.so.1

2. If the file is found, you can add its directory to the `LD_LIBRARY_PATH` environment variable. For example, if the file is located at `/path/to/libmkl_rt.so.1`, you can set the variable like this:

   export LD_LIBRARY_PATH=/path/to:$LD_LIBRARY_PATH

Note: It's recommended to add this line to your shell startup file (e.g., `.bashrc` or `.bash_profile`) to make it persistent.

3. If the file is not found, you might need to install Intel MKL or ensure that it is properly installed on your system. You can download it from the Intel website and follow the installation instructions specific to your operating system.

If the issue persists after trying these steps, please provide more details about your system configuration and how you are using MKL, so that I can assist you further.
