TypeError: only integer scalar arrays can be converted to a scalar index

[glescki]

Hi,

I'm following the first tutorial (RadIO.I.ipynb) and I always seem to get the same error. I've tryed with different data than from the Luna dataset and I get the same error.

After running this line:

batch = (luna_dataset >> preprocessing).next_batch(batch_size=3, shuffle=False)  # execution starts when you call next_batch

I get:

---------------------------------------------------------------------------

TypeError                                 Traceback (most recent call last)

TypeError: only integer scalar arrays can be converted to a scalar index

I'm running the notebook on google colab, but I also get the same error when running in my laptop.

What I am doing wrong here?

Same error, different dataset.

@AlexeyKozhevin @akoryagin Guys, please, comment

Could you print pos and self.index in subset_by_pos method?
