Basically is there a Numpy or PyTorch function that does this:
dims = vp_sa_s.size()
for i in range(dims(0)):
for j in range(dims(1)):
for k in range(dims(2)):
#to mimic matlab functionality: vp(mdp_data.sa_s)
try:
vp_sa_s(i,j,k) = vp(mdp_data('sa_s')(i,j,k))
except:
print('didnt work with' , mdp_data('sa_s'))
Given that vp_sa_s
is size (10,5,5)
and each value is a valid index vp i.e in range 0-9. vp is size (10,1)
with a bunch of random values.
Matlab do it elegantly and quickly with vp(mdp_data.sa_s)
which will form a new (10,5,5)
matrix. If all values in mdp_data.sa_s
are 1, the result would be a (10,5,5)
tensor with each value being the 1st value in vp
.
Does a function or method that exists that can achieve this in less than O(N^3) time as the above code is terribly inefficient.
Thanks!
