Convert a str(numpy array) representaion to a numpy array - Python

Question

Let's say I have a numpy array a = numpy.array([1,2,3,4]). Now str(a) will give me "[1 2 3 4]". How do I convert the string "[1 2 3 4]" back to a numpy.array([1,2,3,4])?

I would ask why you want to do that instead of just keeping the array, but you can "split" on the spaces. arr = numpy.array(s.split(' ')) — Christian Sloper, Nov 22 '19 at 11:25

Try numpy.array([int(v) for v in your_str[1:-1].split()])
