Convert String of an int array to a Numpy array of ints

[mdsousa]

Hi

I am sending a Numpy int array over RabbitMQ and it seem to be receiving correctly.

This is the output RabbitMQ's publish that is sent:

>py msg_send_test.py

Output:
 [x] Sent '0,1617731222,1617731222810382600,4,[ 48 251   9 205]'

This is the output on the receiving end from RabbitMQ's consumer:
>py msg_receive_test.py

Output:
 [*] Waiting for messages. To exit press CTRL+C
[x] message      '0,1617732445,1617732445003573700,4,[209 227 205  72]'
[x] message type <class 'str'>
[x] parts        ['0', '1617732445', '1617732445003573700', '4', '[209 227 205  72]']
[x] parts len    5
[x] imageStr     [209 227 205  72]
[x] imageStr type <class 'str'>

This is the section of code to produce the output from the RabbitMQ consumer:

    message = body.decode()
    parts = message.split(',')
    print("[x] message      %r" % message)
    print("[x] message type %s" % type(message))
    print("[x] parts        %s" % parts)
    print("[x] parts len    %s" % len(parts))
    imageStr = str(parts[4])
    print("[x] imageStr     %s" % imageStr)
    print("[x] imageStr type %s" % type(imageStr))

What I would like to do is convert the imageStr into a Numpy array of ints. The whole array is a string, not an array of individual strings.

Any suggestions would be appreciated.

Thanks...

When I try using Numpy's fromstring method:

    imageArr = np.fromstring(imageStr, dtype=float, sep=' ')
    print("[x] imageArr type %s" % type(imageArr))
    print("[x] ", imageArr)

it gives the following output:

Output:
[x] imageStr type <class 'str'>
[x] imageArr type <class 'numpy.ndarray'>
[x]  []
