Ex_4_v4 error.pdf (81.0 KB)
Hi,
I am puzzled with this error:
‘only size -1 arrays can be converted to Python scalars’
pointing to a sentence of the test.
I cannot figure out the instance that originate it. I suspected could be X and Y, but all I have tried did not work. Could you give me a hint of its origin?
I have also a doubt with the shifting of Y, Should we to consider leading [None] position of X as part of its length or not.
Many thanks for your help
Can you upload the document here as an image? I’m not likely to open a mysterious PDF file.
The problem is that your X and Y values are lists containing other lists, but they should be simple lists. For comparison, here’s what I see from that same section:
j = 0 idx = 0
single_example = turiasaurus
single_example_chars ['t', 'u', 'r', 'i', 'a', 's', 'a', 'u', 'r', 'u', 's']
single_example_ix [20, 21, 18, 9, 1, 19, 1, 21, 18, 21, 19]
X = [None, 20, 21, 18, 9, 1, 19, 1, 21, 18, 21, 19]
Y = [20, 21, 18, 9, 1, 19, 1, 21, 18, 21, 19, 0]

See the difference? Your X is a list containing two elements: the first is None and the second is a list containing 11 elements. My X is a simple list containing 12 elements. So how did that happen?
Hi @paulinpaloalto,
Yes, I suspected it from the description, but I tried ravel() and Flatten() without results, and as the error points to the test I got stuck.
Your words and examples brought me to the correct track again. Building X and Y with np.hstack solved the question but I imagine that there are many more ways of solving the problem.
Many Thanks
