This line of code sets the environment variable "OMP_NUM_THREADS" to the value "1".
The OpenMP library is used for parallel computing on shared memory systems, and the OMP_NUM_THREADS variable determines the number of threads that will be used for parallel processing.
Setting it to "1" means that only one thread will be used, which can be useful for debugging or for ensuring reproducibility of results. However, it can also result in slower performance if the program is designed to take advantage of parallel processing.
