The NVidia T4 GPU seems to have only 16GB of available memory – likely the issue is the size of the problem representation is too large to be run on a GPU of that size (I assume you have 1 qubit per feature, 26 features → 26 qubits). Though, overall, for 26 qubits you will need 16 bytes per complex value, and 2^26 values, which will require around 1GB of memory just for the statevector storage alone. Without explicitly seeing your circuit I cannot recommend further, but you should have enough memory available to store and evaluate this computation on a GPU of that size. Can you provide a minimum working example of your script that reproduces this error?
With that we should be able to better advise the next steps.
