error: non-aggregate type 'std::vector

I am using visual studio code for coding, and I came to this error :

error: non-aggregate type 'std::vector' cannot be initialized with an initializer list std::vector Tests = {1, 1....

this the line of code :

std::vector<float> Tests = { 1, 1, 1, 1, 1, 1, 1, 1, 1 };

I have included vector,

Do you know what should i do ? Thank you
