[capcarr]

Hi, could you please specify the version of biosppy that you are using (biosppy.__version__)?
Also, could you provide access to the resp signal that causes the error?

[YutaForLab]

The version is 0.2.2, and the path of resp signal is as follow:

thank you for your quick reply.

What's the sampling rate of the signal?

[YutaForLab]

1kHz it is.

Hi @YutaForLab
The function biosppy.signals.resp.resp seems to be working with the signal you provided.
Could you please send the complete stack trace, and the versions of numpy and scipy that you have installed?

[YutaForLab]

Sorry for late to replying.
numpy version is 1.11.1 and scipy version is 0.18.0rc2.
And traceback is as below:

Traceback (most recent call last):

thanks a lot.

Hi @YutaForLab
This bug does not happen with the latest version in the GitHub repo (as of commit cae32b0). The code in PyPI does not yet have these updates.
I would recommend reinstalling with the GitHub version.
