Inheritance also applies to annotated types. Any instance of Foo which is a subtype of FooBase is also a valid object of the type FooBase. So you can pass a FooBase object but also a Foo object to the function. If you want to limit the function to only subclasses of FooBar, you could take … Read more
The type of the cell values are, by default, non-numeric. argmin(), idxmin(), argmax() and other similar functions need the dtypes to be numeric. The easiest solution is to use pd.to_numeric() in order to convert your series (or columns) to numeric types. An example with a data frame df with a column ‘a’ would be: df[‘a’] … Read more
In a tl;dr fashion: This is because two functions exist for the two different cases, as can be seen in unicode_strip; do_strip and _PyUnicodeXStrip the first executing much faster than the second. Function do_strip is for the common case str.strip() where no arguments exist and do_argstrip (which wraps _PyUnicode_XStrip) for the case where str.strip(arg) is … Read more
You should cast it to text as the error explains. To do so, adapt the following code to your needs 🙂 from sqlalchemy.sql import text … cursor.execute(text(<whatever_needed_to_be_casted>))
There is a javascript function called execute_cells (see it on Github) that when given an list of cell indices runs those cells. %%javascript Jupyter.notebook.execute_cells([0]) # 0 to run first cell in notebook etc. If you need to run it specifically in a Python code cell, one can use the Javascript function in the IPython.display module … Read more
Use the disp argument to fit. It controls the verbosity of the optimizers in scipy. mod.fit(disp=0) See the documentation for fit.
If you import like this from imblearn.over_sampling import SMOTE you need to do fit_resample() oversample = SMOTE() X, y = oversample.fit_resample(X, y)
EDIT # 2 PIL.Image.frombytes(‘RGB’, fig.canvas.get_width_height(),fig.canvas.tostring_rgb()) takes around 2ms compared to the 35/40ms of the below. This is the fastest way I can find so far. I’ve been looking at this also today. In the matplotlib docs the savefig function had this. pil_kwargsdict, optional Additional keyword arguments that are passed to PIL.Image.save when saving the figure. … Read more
Just call the bytes constructor. As the docs say: … constructor arguments are interpreted as for bytearray(). And if you follow that link: If it is an iterable, it must be an iterable of integers in the range 0 <= x < 256, which are used as the initial contents of the array. So: >>> … Read more
This is a problem of an old version of pypdf. The history of pypdf is a bit compliated, but the gist of it: Use pypdf>=3.1.0. All lowercase, no number. Since December 2022, it’s the best supported version. Install pypdf $ sudo -H pip install pypdf You might need to replace pip by pip2 or pip3 … Read more
