Pinkfish package

Try.

#return pd.isnull(self._tlog).any(1).nonzero()[0]
return pd.isnull(self._tlog).any(1).to_numpy().nonzero()[0]

A other option had to been running in a virtual environment.
Then clone Repo and install requirements.txt

git clone https://github.com/fja05680/pinkfish.git
pip install -r requirements.txt 

Now will running with versions that was used when this was made.

Thank you very much for your time.
I tried
return pd.isnull(self._tlog).any(1).to_numpy().nonzero()[0]
still have error message

I tried nonempty to replace nonzero still not working.

I also tried to downgrade the pandas to 0.24.2. then I ran into so many other error codes on my existing code.
so a downgrade pandas is not a good option I think.

I was reading at pandas.pydata.org, didn't see much info regarding to_numpy().nonzero()[0]

is there any alternative ?
