kandi X-RAY | coz Summary

coz is a C library typically used in Performance Management, Monitoring applications. coz has no bugs, it has no vulnerabilities and it has medium support. However coz has a Non-SPDX License. You can download it from GitHub.

Coz is a new kind of profiler that unlocks optimization opportunities missed by traditional profilers. Coz employs a novel technique we call causal profiling that measures optimization potential. This measurement matches developers' assumptions about profilers: that optimizing highly-ranked code will have the greatest impact on performance. Causal profiling measures optimization potential for serial, parallel, and asynchronous programs without instrumentation of special handling for library calls and concurrency primitives. Instead, a causal profiler uses performance experiments to predict the effect of optimizations. This allows the profiler to establish causality: "optimizing function X will have effect Y," exactly the measurement developers had assumed they were getting all along. Full details of Coz are available in our paper, Coz: Finding Code that Counts with Causal Profiling (pdf), SOSP 2015, October 2015 (recipient of a Best Paper Award).

Move const appHistory = createBrowserHistory() out of the component. You want a stable history reference.

You'll need to implement some history state as well. Use the BrowserRouter source code as the example for how the high-level routers instantiate their history context.

You could do a double groupby where in the first round, you groupby "Name" to group "Subset", "Type", and "System"; then again by these columns to group "Name"s.

GradientTape returning None when run in a loop

Asked 2022-Mar-23 at 17:30

The following gradient descent is failing 'coz the gradients returned by tape.gradient() are none when the loop runs second time.

...

ANSWER

Answered 2022-Mar-23 at 17:30

This is because assign_sub returns a Tensor. In the line w = w.assign_sub(0.001*dl_dw) you are thus overwriting w with a tensor with the new value. Thus, in the next step, it is not a Variable anymore and is not tracked by the gradient tape by default. This results in the gradient becoming None (tensors also do not have the assign_sub method, so that would crash as well).

Instead, simply write w.assign_sub(0.001*dl_dw) and same for b. The assign functions work in place, so no assignment is necessary.

The part you are missing is from this part of the migration guide: https://mui.com/material-ui/guides/migration-v4/#style-library.

if you are using JSS style overrides for your components (for example overrides created by makeStyles), you will need to take care of the CSS injection order. To do so, you need to have the StyledEngineProvider with the injectFirst option at the top of your component tree.

Without this, the default styles for the MUI Card in your About component win over the styles specified via classes.about where the styles overlap (e.g. background).

Changing your AllProviders component to the following (just adding ) fixes it:

How to have two Secondary Actions in react material, One on left corner and one on right without affecting the behaviour of secondary action

Asked 2022-Feb-21 at 17:52

I need to show two secondary action one on left end(eye icon) and one on right end(delete icon) of the list item. The position I can adjust by overriding css elements right & left.

The problem is Secondary action delete is also triggering the ListItem's onClick event. because in code the order is like below, first delete, and at last eye component is written.
