Thenumpy.ceil()method returns the ceiling of the supplied array, element-wise. The ceil of the scalarxis the smallest integeri, such thati>=x. #If you only want to round down, usenumpy.floor If you only want to round the numbers in an array down, use thenumpy.floor()method. ...
# Define portfolio weights (e.g., 50% AAPL and 50% MSFT) weights = np.array([0.5, 0.5]) # Calculate portfolio returns portfolio_returns = daily_returns.dot(weights) # Calculate cumulative returns for each asset cumulative_returns = (1 + daily_returns).cumprod() - 1 # Calculate Sharpe ...
I think it would be nice to have better error-handling in this situation, but using default_factory is definitely the right way to handle the setting of a default value of anything mutable (such as a numpy array) on a pydantic model. dmontagu self-assigned this Apr 28, 2023 Contributor...

For instance, this could allow you to have a parameter that is simply a string in json, but the deserialization routine loads uses that string to look something up in a database and return a numpy array, or have a string which is actually a filepath to an image file, and deserializes...
