It must relate to the renaming and deprecation of cross_validation sub-module to model_selection. Try substituting cross_validation to model_selection
The names (column names) of the first dataframe do not match the names of the second one. Just as the error message says. If you do not care about the names of the 3rd or 4th columns of the second df, you can coerce them to be the same: Then things should proceed happily.
The or and and python statements require truth-values. For pandas these are considered ambiguous so you should use “bitwise” | (or) or & (and) operations: These are overloaded for these kind of datastructures to yield the element-wise or (or and). Just to add some more explanation to this statement: The exception is thrown when you want to get the bool of a pandas.Series: What you hit was a place where the operator implicitly converted … Read more
The error “only length-1 arrays can be converted to Python scalars” is raised when the function expects a single value but you pass an array instead. If you look at the call signature of np.int, you’ll see that it accepts a single value, not an array. In general, if you want to apply a function that … Read more
The maximum number of days in a year is 366, this gives us 52 full weeks. In those 52 weeks there are at least 52 * 5 = 260 weekdays. We are left with 2 days (52 * 7 = 364), it is possible that these 2 days are weekdays. So maximum number of weekdays … Read more

Transparency is controlled by the alpha channel (AA in #AARRGGBB). Maximal value (255 dec, FF hex) means fully opaque. Minimum value (0 dec, 00 hex) means fully transparent. Values in between are semi-transparent, i.e. the color is mixed with the background color. To get a fully transparent color set the alpha to zero. RR, GG and BB are irrelevant in this case … Read more
np.max is just an alias for np.amax. This function only works on a single input array and finds the value of maximum element in that entire array (returning a scalar). Alternatively, it takes an axis argument and will find the maximum value along an axis of the input array (returning a new array). The default behaviour of np.maximum is to take two arrays and compute … Read more
It’s quite common to have a layout like this… …with a mymodule.py like this… …a myothermodule.py like this… …and a main.py like this… …which works fine when you run main.py or mypackage/mymodule.py, but fails with mypackage/myothermodule.py, due to the relative import… The way you’re supposed to run it is… …but it’s somewhat verbose, and doesn’t mix well with a shebang line like #!/usr/bin/env python3.
