kandi X-RAY | ctp Summary

ctp is a C library. ctp has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

CTP is a Linux user space application which lets you pass hundreds of megabits of ethernet traffic through an off the shelf PC. Frames can be manipulated, filtered and generated with a flexible and configurable processing pipeline. CTP was tested in 2012 to process 350 Mbp/s with 0% drop and ms-level jitter. The drops occured at the capture level, so with off the shelf capture NICs one could probably achieve full wirespeed.

Using older word processing software applications there seems to be problems when LTR characters and RTL characters gets mixed in one text run. Then using special BiDi character types might be the solution. See https://en.wikipedia.org/wiki/Bidirectional_text#Table_of_possible_BiDi_character_types.

Using this the following works:

QUESTION

how often are update_state() and call() method called and what are the dimension of the parameters in tf.keras?

Asked 2021-Apr-30 at 07:47

I would like to know

(1) how often the call() method of tf.keras.losses.Loss and the update_state() method of tf.keras.metrics.Metric gets called during a training:

are they called per each instance (observation)?
or called per each batch?

(2) the dimension of y_true and y_pred passed to those methods:

are their dimension (batch_size x output_dimension)
or (1 x output_dimension)

The following code snippet comes from https://www.tensorflow.org/guide/keras/train_and_evaluate

For experiment I insert print(y_true.shape, y_pred.shape) in update_state() and I find that it is only printed once in the first epoch. From the print, it looks like y_true and y_pred have the dimension of (1 x output_dimension) in this particular example but is it always the case?

So, additionally

(3) I would like to know why it is printed only once and only in the first epoch.

(4) I can't print the value of y_true or y_pred. How can I?

(1) how often the call() method of tf.keras.losses.Loss and the update_state() method of tf.keras.metrics.Metric gets called during a training:

The call method of tf.keras.losses.Loss and the update_state() are used at the end of each batch.

(2) the dimension of y_true and y_pred passed to those methods:

The dimensions of y_true is same as what you pass in y_train. The only change is, the first dimension of y_train will be no_of samples and in the case of y_true it will be batch_size. In your case it is (64, 1) where 64 is batch_size.

The dimensions of y_pred is the shape of output of the model. In your case it is (64, 10) because you have 10 dense units in final layer.

(3) I would like to know why it is printed only once and only in the first epoch.

The print statement is executed only once because tensorflow is executed in graph mode. Print will only work in eager mode. Add run_eagerly = True in model.compile step if you want to execute tensorflow code in eager mode.

(4) I can't print the value of y_true or y_pred. How can I?

Run the code in eager mode.

You always append to loop2200using index1[0] and index1[1], but new indexes are being appended to index1: change these to index1[-2] and index1[-1] (i.e. using the last two indexes added to index1) and that will update loop2200 correctly.

Applescript Mail - Script won't get past ''on perform mail action with messages theMessages for rule theRule"

I have set up a rule that when a email comes in from a certain sender an Applescript gets triggered. I would like that the Applescript extracts contents from the mail that triggers the rule to be send to a PHP script that sends it as a webhook to a database. Everything works except for the the code won't run past 'on perform mail action with messages theMessages for rule theRule', it just skips that block of code and will never get to the repeat block.

What am I doing wrong?

If you need any more info I would be happy to provide.

The do shell script line must be inside the handler. And you have to quote all parameters and coerce theDate to text.

Cakephp memory limit error after migration, troubleshooting Controller

Asked 2020-Jul-09 at 16:03

I'm copying/migrating a production server Cakephp 2.3.8 project into a development one but I get the famous error:

Blockquote Fatal Error Error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 200648563 bytes) File: /var/www/html/lib/Cake/Utility/String.php Line: 243

Notice: If you want to customize this error message, create app/View/Errors/fatal_error.ctp

I have already mirror the same specs that the production server:

Tried to increase the default memory limit on apache > php.ini file from 128M to 1024
Also 1024 to 2048, but no luck
Restarted the server and apache service
Limit the data set on my database (currently have 6, but the production server has about 40K rows on the table that I'm querying)
Tested a function inside the controller to just display a single line of text (successfully displays it, but the Fatal error message keeps showing up).

This mostly happens when I visit certain controllers because I'm able to load some pages correctly (apparently).

I'm currently debugging the behavior of the app on the log files:

/ppp/tmp/logs/error.log
Xdebug

But none of them shows more details that the Fatal error limit, I was told that it might be a memory leak, buy how come if both servers are limited the same way ? (ulimit for servers below).

I would like to know what the problem is, I'm I missing a setting? How could I adjust a Controller in a way to run without errors?

You don't have to fetch as list, you can work your way trough by just fetching categories with its subcategories and then build your HTML/JS from there.
