MemoryError, Unable to allocate memory for array

I’m running ODQA with my own set of about 75000 text files however when trying to run the model I get:

MemoryError: Unable to allocate 9.20 GiB for an array with shape (25711598, 96) and data type float32

I have already tried to give all the memory to pycharm
And have about 20gb of RAM available. So what is wrong here?
I also saw that a single CPU core is being used 100%, while I have 8 cores…
How can I enable all my cores to be used with DeepPavlov?
Can you tell me how I fix this?
