@acer9997 thanks for reporting! what do you mean by install utils separately? utils is referring to a module inside this package (https://github.com/plotly/plotly.py/blob/master/plotly/utils.py) not a separate package.

[actongorton]

Sorry - I'm out of sorts this morning! I had two different environments running and didn't realize what I was doing. The error is still appearing. I removed that other misleading comment.

[chriddyp]

got it, thanks @acer9997 . I'm not sure what's going on here yet

[chriddyp]

@acer9997 - do you think it could be conflicting with the package that you have installed called utils? In your requirements.txt:

utils (0.9.0)

Thanks again for reporting!

[actongorton]

@chriddyp - it could be.

I uninstalled utils and tried importing plotly again, but got a different error that I don't think is related to Plot.ly and has been occurring when trying to import matplotlib in other situations:

ValueError: insecure string pickle

[actongorton]

Okay, I think that I've found something more consistent with this.

If I import matplotlib before trying to import plotly, then the "cannot import name utils" error appears.

If I restart the Python kernel and skip trying to load matplotlib, then the utils error does not appear.

I'm using inotebook and have been trying to figure out why I've been getting the insecure string pickle error with matplotlib, which is why I was trampling on top of other libraries.

Hi @actongorton, I'm going to close this issue for now since plotly.py has been largely rewritten over the last two years, but feel free to open a new issue if you're having similar problems with ploty.py version 3. Thanks!
