I can view on TensorBoard the computation graph I have constructed and through the browser I can also download its PNG.
Is there a way to download the graph through code (without opening the browser)?
I have tried to inspect the HTML page, but unfortunately there is no direct link I can copy.

Good afternoon,
Any knows why when I make a group post through the API with for example the following link:
- https://www.motocasiao.pt/advert/8F70CC3EF/ktm-1190-adventure
No preview is generated, only the url is shown..
Output: https://prnt.sc/q05517
Thanks in advance

When content is shared for the first time, the Facebook crawler will scrape and cache the metadata from the URL shared. The crawler has to see an image at least once before it can be rendered. This means that the first person who shares a piece of content won't see a rendered image.
There are three ways to avoid this and have images render on the first Like or Share action:
Pre-cache the image with the Sharing Debugger: Run the URL through the URL debugger to pre-fetch metadata for the page. This can also be used to update the image for a piece of content.
Pre-cache the image using Graph API: Perform a force-scrape of the URL programmatically using the Graph API to pre-fetch metadata for the page . This can also be used to update the image for a piece of content.
Use og:image:width and og:image:height Open Graph tags: Using these tags will specify the image dimensions to the crawler so that it can render the image immediately without having to asynchronously download and process it.
I am trying to access a proprietary website which provides access to a large database. The database is quite large (many billions of entries). Each entry in the database is a link to a webpage that is essentially a flat file containing the information that I need.
I have about 2000 entries from the database and their corresponding webpages in the database. I have two related issues that I am trying to resolve:
How to get wget (or any other similar program) to read cookie data. I downloaded my cookies from google chrome (using: https://chrome.google.com/webstore/detail/cookiestxt/njabckikapfpffapmjgojcnbfjonfjfg?hl=en) but for some reason the html downloaded by wget still cannot be rendered as a webpage. Similarly, I have not been able to get Google Chrome from the command line to read cookies. These cookies are needed to access the database, since they contain my credentials.
In my context, it would be OK if the webpage was downloaded as a PDF, but I cannot seem to figure out how to download a webpage as a pdf using wget or similar tools. I tried using automate-save-page-as (https://github.com/abiyani/automate-save-page-as) but I continuously get an error of the browser not being in my PATH.
I solved both of these issues:
Problem 1: I switched away from wget, curl and python's requests to simply using the selenium webdriver in python. Using selenium, I did not have to deal with issues such as passing cookies,headers, post and get, since it actually opens a browser. This also has a plus that as I was writing the script to use selenium, I could inspect the page and see what it was doing as it was doing it.
Problem 2: Selenium has a method called page_source, which downloaded the html of the webpage. When I tested it, it rendered the html correctly.
I am looking for an example of casting an image to a chrome cast from a url. There doesn't seem to be an image cast example in the google cast sample repositories but i feel this must have been done before.
I have little experience with the chrome cast sdk developer console as well as the development of the apps themselves so any information would be greatly appreciated.
I suggest you look at the CastHelloText-android (or ios) sample on out github repo. What you need to do is to use either a custom reeiver (say, start from the one used in CastHelloText) and add an image html tag and then use the cutom namespace data channel to send the url of your image to your receiver and set that as the source of your image tag. Alternatively, you can use a Styled (or the Default) receiver which supports showing images; create a MediaInfo from your image and just send load it like a video and that should work. Note that your image should be served from an accesisble web server.
From a BHO (Browser Helper Object) in Internet Explorer, how do I get the full source code of the page currently loaded in the web browser when I have its IWebBrowser2 interface?
Do I have to download it again from the url where it resides or is there a way to get the copy that internet explorer downloaded and used to render the page?
I tried getting the outerHTML of the html element of the current document, but it returns the source code already preprocessed. I need to get it in the same form you see it when you clock "View Source Code" in the Internet Explorer.
Thank you for any helpful information!!!
You can query the browser's Document property for IPersistStream or IPersistFile and then call its Save() method. But when querying the browser for its HTML, you are likely to get the processed HTML, which may include DOM changes from scripts.
To get the original HTML, you should download it yourself directly from the source URL, or at least extract the file from the browser's local cache.
I need to take image frames from a webcam server using selenium python module.
The frames webcam is show on the selenium browser ( using http:// .....html webpage) .
The source code of the page show me it's done using some java script.
I try to use:
capture_network_traffic() and captureNetworkTraffic
Not working , also I don't think is a good way to do that.
Also I don't want to use capture_screenshot functions , this take all canvas of the browser.
Any idea ?
Thank you. Regards.
First, what you'll need to do is navigate to the webpage with Selenium.
Then, analyse the web page source HTML which the Javascript will have rendered by you navigating to the page, to get the image URL. You can do this with Selenium or with an HTML parser.
Then you can easily download the image using wget or some other URL grabber.
You might not even need Selenium to accomplish this if when you get the page, the image is already there. If that is the case you can just use the URL grabber to get the page directly.
Let me know if you want more details or if you have any questions.
