kandi X-RAY | rattle Summary

rattle is a Python library typically used in Blockchain, Ethereum applications. rattle has no bugs, it has no vulnerabilities, it has build file available and it has high support. You can download it from GitHub.

Rattle is an EVM binary static analysis framework designed to work on deployed smart contracts. Rattle takes EVM byte strings, uses a flow-sensitive analysis to recover the original control flow graph, lifts the control flow graph into an SSA/infinite register form, and optimizes the SSA – removing DUPs, SWAPs, PUSHs, and POPs. The conversion from a stack machine to SSA form removes 60%+ of all EVM instructions and presents a much friendlier interface to those who wish to read the smart contracts they’re interacting with.

            Include spaces when counting the length of a string
            Asked 2022-Mar-30 at 11:50

            Im trying to create a simple program that reads strings entered by the user and displays the longest and shortest string. The program works fine for single words such as 'dog' or 'cat' but if I was to type 'rattle snake' it takes it as two individual words 'rattle' and 'snake' and not one whole string with a space included. Is there any reason why its registering the space as a divider/separator and not treating it as one whole string? Thank you!

            How to do a two-step lookup using jq?
            Asked 2021-Oct-15 at 19:34

            My bank provides a very poor excuse for transaction export which makes doing reconciling receipts for taxes way more difficult than it needs be, fortunately their web site is an SPA that is chock-full of rich json formatted data.

            Having extracted all of the transaction data for a year, I'd now like to transform that data into filenames (date - cat - desc - amt.pdf) to use for receipt scans to help speed up the reconciling process.

            I'm close to being able to do this but a doing a double lookup has stumped me and I could use the help of someone more well versed in jq.

            • It seems that the direction parameter must be numeric.
            • Create a dict where each key is a each direction in 'WindGustDir' and the corresponding value is a float in degrees.
            • .map the dict to df.WindGustDir and plot
            • Alternatively, create and plot a new column

            Asked 2021-May-25 at 15:17

            I am trying to create a node-link diagram (decision tree) by using parsnip and tidymodels. What I am performing is building a decision tree model for the StackOverflow dataset using the tidymodels package and rpart as model engine. The model should predict whether a developer will work remotely (variable remote) based on the number of years of programming experience (years_coded_job), degree of career satisfaction (career_satisfaction), job title "Data Scientist" yes/no (data_scientist), and size of the employing company (company_size_number).

            If you are going tidymodels and parsnip to fit your model, it's better to use that actual fitted model for any visualizations like this. You can get the underlying engine object from a parsnip model using $fit.

            Answered 2021-Apr-10 at 08:20

            Have you tried your own roc_auc scoring rule? It seems like you are passing labels instead of probabilities (you originally need) for roc_auc.

            problem described in here: Different result roc_auc_score and plot_roc_curve

            Solutions for own scorers: Grid-Search finding Parameters for AUC

            Update2

            Sorry, saw today that my introduction text from the notebook was missing lol

            When calculating roc_auc_score you have the option (it doesnt matter, if it is with or without gridsearch, with or without pipeline) that you can pass it labels like (0/1) or probabilities like (0.995, 0.6655). The first should be easy available if you just convert your probas to labels. However that would result in a (straight reversed L) output plot. That looks sometimes ugly. the other option is to use predicted probabilites to pass them them to the roc_auc_score. That would result in a (staircase reversed L) output plot, which looks much better. So what you first should test is, can you get a roc auc score with labels, with and without grid, if that is the case. You should then try to get probabilities. And there, I believe, you have to write your own scoring method, as the roc-auc_score in grid only serves labels, that would result in high roc_auc scores. I wrote something for you, so you can see the label approach:
