save

问题 So i'm legit confused. It won't compile for an external serialization function. It gives the error cereal could not find any output serialization functions for the provided type and archive combination. So the code below doesn't compile #include <fstream> #include <glm/glm.hpp> #include "SceneObject.h" #include <cereal/cereal.hpp> #include <cereal/archives/json.hpp> template<typename Archive> void serialize(Archive& archive, glm::vec3& v3) { archive(cereal::make_nvp("x", v3.x), cereal::make

问题 I cannot find a clear guide on how to build an SQL database which can interact with python code. What I want to do is have an SQL database which can save certain variables from my python code, so that I can load them later from the database. This should be able to support multiple users, so users should need to put in their username and password to access their information in the database. Does anybody have code to do this, or know of a guide that could help me out? Thanks :) P.S. I know

问题 When a user opens up this workbook, I want to force them to save the file as a new file immediately. The dialog box opens up but it will only let you save it as "All Files". Dim Workbook_Orig As Variant Workbook_Orig = Application.GetSaveAsFilename If Workbook_Orig <> False Then ActiveWorkbook.SaveAs _ Filename:="File Name", _ FileFormat:=52 End If In place of the "52" I've tried "xlOpenXMLWorkbookMacroEnabled" but that made no difference. Can you not SaveAs immediately? Do you have to make a

问题 I am trying to re-create the prediction of a trained model but I don't know how to save a model. For example, I want to save the trained Gaussian processing regressor model and recreate the prediction after I trained the model. The package I used to train model is scikit-learn. kernel = DotProduct() + WhiteKernel() gpr = GaussianProcessRegressor(kernel=kernel,random_state=0) gpr.fit(X,y) 回答1: You can use: 1. pickle from sklearn import svm from sklearn import datasets iris = datasets.load_iris

问题 I wrote some functions on Jupyter notebook and want to save the script in form of .py, but anaconda jupyter notebook automatically saves the script as .ipynb, How can I change it to .py for this specific script? Is there any command for it? Thanks 回答1: There are built-in Magic commands in Jupyter: IPython has a set of predefined ‘magic functions’ that you can call with a command line style syntax. There are two kinds of magics, line-oriented and cell-oriented. Line magics are prefixed with

问题 I have implemented a reorder recyclerview in my app as per the following link: https://www.appliedcodelog.com/2019/08/reorder-list-items-by-drag-and-drop-in.html The user can add and click on any of the items to change the qty and unit type and also add the price of the item via a custom dialog (see attached screen shots). Currently the item names are saved by converting the list to Json. So when the app is reopened the items are loaded back into the list. My question is, how can I also save

问题 I would like to save the dictionary having tuple on keys. I tried pickle, ujson, json to save the dictionary. All of them did not work. The dictionary has: dictionary = {(-30, -29, -72, -71): [[-29.99867621124457, -71.75349423197208, 220], [-29.996964568219873, -71.7521560207641, 220], [-29.99696437241995, -71.7507330056961, 220], [-29.99761665426199, -71.75016101067708, 220]]} I tried: with open('depth_echo.txt', 'w') as file: file.write(ujson.dumps(dictionary) import json a, b, c = "abc"
