AttributeError: unstack_signals not found in class EcgBatch

Hi I ran into errors when running I.Cardio tutorial file. The script before this works fine, could you help with that?

`original_batch = batch_with_data.deepcopy() changed_batch = batch_with_data.deepcopy()

original_batch.random_split_signals(length=3000, n_segments=4)

changed_batch.random_split_signals(length=3000, n_segments=4).unstack_signals()`

Hi!

Perhaps you use CardIO 0.1.0. The version number can be obtained by running the following commands:

import cardio
print(cardio.__version__)

If that's the case, please, update the package to the latest version.

Hi

Just checked, my version is indeed 0.1.0. Also I have the following warnings:

/Users/yd/anaconda3/lib/python3.6/importlib/_bootstrap.py:219: RuntimeWarning: compiletime version 3.5 of module 'tensorflow.python.framework.fast_tensor_util' does not match runtime version 3.6 return f(*args, **kwds)

Should I be worried about this and update the version of tensorflow to 3.6?

Thanks!

The warning means that your tensorflow version does not match the python version for some reason. Try to update the tensorflow package.

Thanks! Just updated both versions, it works fine now :)
