constants

问题 Using Statsmodels, I am trying to generate a simple logistic regression model to predict whether a person smokes or not (Smoke) based on their height (Hgt). I have a feeling that an intercept needs to be included into the logistic regression model but I am not sure how to implement one using the add_constant() function. Also, I am unsure why the error below is generated. This is the dataset, Pulse.CSV: https://drive.google.com/file/d/1FdUK9p4Dub4NXsc-zHrYI-AGEEBkX98V/view?usp=sharing The full

问题 Here is the example behavioral Verilog code in question module constant; reg [7:0] foo; initial begin foo = 1'bz; $display("%H", foo); end endmodule Icarus Verilog gave me $ iverilog -o constant constant.v $ ./constant 0Z However, according to this website (and the lecturer of an FPGA course I am taking), If number is smaller than the size constant, then it will be padded to the left with zeros. If the most significant bit of a specified number has an unknown (x) or high-impedance (z) value,

问题 I expected the following to work but it doesn't seem to. <?php class Patterns { public static const EMAIL = "/^([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]{2,6}$/ix"; public static const INT = "/^\d+$/"; public static const USERNAME = "/^\w+$/"; } I get syntax error, unexpected T_CONST, expecting T_VARIABLE 回答1: You can use const in class like this: class Patterns { const EMAIL = "/^([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]{2,6}$/ix"; const INT = "/^\d+$/"; const

问题 I'm looking for an effecient way to constantly select the last element within the visible window/viewport. So far, this is my code: $(window).scroll(function () { $('.post-content p').removeClass("temp last") $('.post-content p').filter(":onScreen").addClass("temp") $(".temp").eq(-1).addClass("last") }); As you could probably imagine, this hauls up a lot of resources and doesn't perform very well. Can somebody please suggest from more elegant code? My knowledge of Javascript is very basic, so

问题 In the documentation on built-in constants (excluding site constants) it's stated that: Note: The names None , False , True and __debug__ cannot be reassigned (assignments to them, even as an attribute name, raise SyntaxError ), so they can be considered “true” constants. If I'm not mistaken, True and False became "true" contants in Python 3. (As also described in the duplicate.) Question is, why aren't the other two ( Ellipsis , NotImplemented ) "true" contants? Is there a use case for re

问题 I'm trying to create a dynamic airflow that has the following 2 tasks: Task 1: Creates files with a generated UUID as part of their name Task 2: Runs a check on those files So I define a variable 'FILE_UUID' and sets it as follow: str(uuid.uuid4()). And also created a constant file name: MY_FILE = '{file_uuid}_file.csv'.format(file_uuid=FILE_UUID} Then - Task 1 is a bashOperator that get MY_FILE as part of the command, and it creates a file successfully. I can see the generated files include

问题 I am working on the some kind of the 2D Regression Deep network with keras, but the network has constant output for every datasets, even I test with handmade dataset in this code I feed the network with a constant 2d values and the output is linear valu of the X (2*X/100) but the out put is constant. import resource import glob import gc rsrc = resource.RLIMIT_DATA soft, hard = resource.getrlimit(rsrc) print ('Soft limit starts as :', soft) resource.setrlimit(rsrc, (4 * 1024 * 1024 * 1024,
