Warnings in Python and Anaconda

It seems as if Python developers are having more than a few problems at the moment from a number of sources. I recently wrote about the potential issues for readers of Beginning Programming with Python For Dummies and Python for Data Science for Dummies from Windows 10 (Python and Windows 10). However, some readers have come back afterward to say they’re still seeing warnings. It wasn’t until one of the beta readers for Machine Learning for Dummies also saw some of these warnings that it became apparent that some other problem is at work. A recent upgrade to NumPy 1.10.1 has created these warnings. You can see some message threads about the issue at:

The important thing to remember is that you’ll see warnings, not errors (unless there is a problem Luca, my coauthor for Python for Data Science for Dummies, and I haven’t seen yet). For now, updating all of the Anaconda components is the only way to actually get rid of the warnings, which can prove to be quite a pain. However, the warnings are just that, warnings. The code in the books will still run just fine. The best way to avoid a lot of work and potentially creating yet more problems is to ignore the warnings for now. In order to ignore the warnings, type the following two lines of code:

import warnings
warnings.simplefilter("ignore")

Obviously, the situation is inconvenient for everyone, but the various libraries will get in sync sometime soon and then the warnings will disappear until the next set of updates. Please let me know if you continue to see problems after making this fix at John@JohnMuellerBooks.com.

  1. With the new juypter notebook replacing the old IP{y} notebook, how do you upload the sample files from the book “Python for Data
    Science” ? I don’t see any type of file upload dialog box that can use…

    1. I plan to provide a blog post complete with graphics this upcoming week. You should be able to drag and drop the files onto the Jupyter page. Failing that, there is also an upload button on the lower right side of the page. The message thread at http://stackoverflow.com/questions/29968829/load-local-data-into-ipython-notebook-server can provide you with some additional details. Please let me know if you need additional details. As I said, I do plan to provide a blog post on this topic this upcoming week and would welcome your questions so that I know just how much content to provide.
