How to initialize a tensor[DType.int8] with random values of either: -1, 0, or 1?
Ah, got it. a.unsafe_ptr() not a._take_data_ptr(). My intellisense betrayed me!

"number of elements to fill", I assume that is 100. so: randintDType.int8, 100, -1, 1) then when I try and print: 
[3914:3914:20240711,145433.691824:ERROR file_io_posix.cc:144] open /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq: No such file or directory (2)

Actually, maybe that's right? It explodes when I try and print a though.

Like this? 
    var a = Tensor[DType.int8](100)
    randint[DType.int8](a._take_data_ptr(), 1, -1, 1)
    var a = Tensor[DType.int8](100)
    randint[DType.int8](a._take_data_ptr(), 1, -1, 1)

Point being, I need a way to randomly initialize really large vectors (could be a million dimensions for example)

@benny Playing with hyperdimensional vectors, requires vectors with dimensions over 10,000 to be useful (this is a rule in Vector Symbolic Architecture). For example: https://torchhd.readthedocs.io/en/stable/generated/torchhd.random.html#torchhd.random Except I want to experiment with 3 valued systems rather than two. But anyway, to create a VSA you need operations like element wise multiplication, addition, and other operations (element wise XOR, etc, for the BSC architecture)
