Examples:
Note do not use & or you will get a different result
numpy.where You can use np.where masks as a kind of vectorized if else statement, choosing between elements from either A or B
Examples:
The first option in jax is to use where statements as in the numpy example
import jax.numpy as jnp
x=jnp.array(True) #
#TypeError: Value 'A' with dtype <U1 is not a valid JAX array type. Only arrays of numeric types are supported by JAX.
WARNING:jax._src.lib.xla_bridge:No GPU/TPU found, falling back to CPU. (Set TF_CPP_MIN_LOG_LEVEL=0 and rerun for more info.)
DeviceArray(1, dtype=int32, weak_type=True)
If doing autograd if statements have more constraints.
Control Flow * In jax, grad works through if statements unconstrained
