Not enough memory

[thirtybug]

When I tried to train GLEM as per the instructions, I encountered this error:
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Aborted (core dumped)
I found that the error is typically related to memory allocation issues within the C++ program, rather than being related to Python package dependencies. This error typically indicates that the C++ program has failed to allocate memory, possibly due to insufficient memory, memory leaks, or other memory allocation-related issues.
Can you give me some advice to solve this error?
