Kernel error after updating to Spyder 4.1

Question

I updated spyder to 4.1 in anaconda through (conda update spyder), and it doesn\'t work unless I open it from the anaconda prompt, otherwise it shows this error:

A

Answer 1

Rollback Spyder 4.0.1 in python 3.7 environment and that should do the trick.

Answer 2

ACK, I have observed the same.

Another problems:

1) There is not possible to close the outline panel. 2) Profiler is unable to profile, for example, this program (something with i/o redirection):

def sum_of_harmonic_series(n):
    s = 0
    for k in range(n, 0, -1):
        s += 1 / k
    return s

N = int(input("N: "))  # replace this line with N = 10000 as a workaround  
print('sum = ', sum_of_harmonic_series(N))

Answer 3

(Spyder maintainer here) This problem is a duplicate of this issue and it is fixed in our 4.1.1, released in March 19th 2020.
