The difference here is that will place “Hello world” in the read-only parts of the memory, and making s a pointer to that makes any writing operation on this memory illegal. While doing: puts the literal string in read-only memory and copies the string to newly allocated memory on the stack. Thus making legal.
you can use plt.matshow() instead of plt.imshow() or you can use seaborn module’s heatmap (see documentation) to plot the confusion matrix
You need to alias the subquery. or to be more explicit
I got this issue on Rasberry PI and found that the root cause was missing library: Then it takes few minute to google the required library source: I have not checked the solution on any other Linux-es but likely the same method should be applicable. So try to import the faulty library first and see … Read more

The problem with using the -e flag for pip install as suggested in the comments and this answer is that this requires that the original source directory stay in place for as long as you want to use the module.
