show() Exception: Data must be 1-dimensional

[pedrinimm]

When It tries to show any result from the som like: codebook, cluster, or hitmap the normalisation method estimates the mean and the std with pandas. However since data is not 1 dimensional and exception gets triggered

could you please show your code?

Hi,
happened to me as well. Problem was I used regular Python array instead of Numpy array. I wrapped my data as follows:

import numpy as np
data = np.array(list_data)

Not sure if it's your case as well.
