"[SpyderKernelApp] WARNING | No such comm:" bm3d error in python trough spyder in a mac

I recently installed bm3d noise reduction algorithm on my mac by typing

pip install bm3d

on the terminal.

Everything seemed ok.

However, every time I try to run it I get the same error

[SpyderKernelApp] WARNING | No such comm:

followed by a Hex number such as in

[SpyderKernelApp] WARNING | No such comm: 74d9826ed0f911ea817428cfe91fcdb3

or in

[SpyderKernelApp] WARNING | No such comm: 4a205fd8d0fa11ea817428cfe91fcdb3

.

I'm running a pretty simple code such as

from bm3d import bm3dimport numpy as npbm3d(np.random.rand(100,100),100)

.

The error seems to have nothing to do with bm3d.

I'm running Python 3.8 trough Spyder 4.1.4 in macOS Mojave 10.14.6.

Any thoughts?

Thanks!
