From Matlab to Python

[erbab]

Hi all!

I am working on a sound classification project. I have written codes in Matlab, but I need to convert it into Python to use with Raspberry Pi. However, I am not very experienced in Python, so I could not convert some parts of the code.

Here is the Matlab version of the code;

"
clc
close all

load output.mat
d=2*44100;
m=1;
for i=2:41
C1=output{i,1};
r= floor(size(C1,1)/d);
for j=1:r
C1_Data(m,:)=C1(1+((j-1)*d):(d+((j-1)*d)));
m=m+1;
end
"

Here is the Python version which is created by me. However, I could not avoid errors.

"

output = np.concatenate((a1,a2,a3,a4,a5,a6,a7,a8,a9))

d=244100
m=1

C1_Data = pd.DataFrame(reweightTarget, columns = ('Sound Class'))

for i in range(0,43):
C1 = output[i][0]
r = math.floor(C1.size/d)
for j in range (1,r):
s=C1[1+((j-1)d):(d+((j-1)*d))]
C1_Data.loc[m]=[s]
m +=1 "
The error

"index(...) must be called with a collection of some kind 'Sound Class' was passed"


If you can help me solve the problem, I will be grateful.
