render a markdown file to pdf with rmarkdown::render() and adjust page margins and font
I'd like to render a simple markdown file, that has been created by another process before, into a pdf file. The command: rmarkdown::render(input = "my_report.md", output_format = rmarkdown::pdf_document(latex_engine = "xelatex")) just does this job. However I would like to change the margins and the main font. With an .Rmd file one would define these settings in the Yaml header like this: --- output: pdf_document: latex_engine: xelatex mainfont: LiberationSans geometry: "left=5cm,right=3cm,top=2cm,bottom=2cm" --- But the markdown files I'd like to convert don't have a Yaml header. Is there a way to pass these Yaml options to the render function as function parameters or in an indirect way? -

Keras loss value very high and not decreasing
Firstly, I know that similar questions have been asked before, but mainly for classification problems. Mine is a regression-style problem. I am trying to train a neural network using keras to evaluate chess positions using stockfish evaluations. The input is boards in a (12,8,8) array (representing piece placement for each individual piece) and output is the evaluation in pawns. When training, the loss stagnates at around 500,000-600,000. I have a little over 12 million boards + evaluations and I train on all the data at once. The loss function is MSE. This is my current code: model = Sequential() model.add(Dense(16, activation = "relu", input_shape = (12, 8, 8))) model.add(Dropout(0.2)) model.add(Dense(16, activation = "relu")) model.add(Dense(10, activation = "relu")) model.add(Dropout(0.2)) model.add(Flatten()) model.add(Dense(1, activation = "linear")) model.compile(optimizer = "adam", loss = "mean_squared_error", metrics = ["mse"]) model.summary() # model = load_model("model.h5") boards = np.load("boards.npy") evals = np.load("evals.npy") perf = model.fit(boards, evals, epochs = 10).history model.save("model.h5") plt.figure(dpi = 600) plt.title("Loss") plt.plot(perf["loss"]) plt.show() This is the output of a previous epoch: 145856/398997 [=========>....................] - ETA: 26:23 - loss: 593797.4375 - mse: 593797.4375 The loss will remain at 570,000-580,000 upon further fitting, which is not ideal. The loss should decrease by a few more orders of magnitude … -

Yandex Disk api image link gets 403 error when the image is added from javascript
I have a python script that uploads images to Yandex Disk using the yadisk module. The script looks like this: def uploadYandexDisk(path, filename): try: y.upload(filename, path) y.publish(path) # I don't know if this is necessary return y.get_download_link(path) except Exception as e: print(e) return None I get a link that looks similar to this: https://downloader.disk.yandex.ru/disk/bfa79f689c05d8baadcf95f4d3ed8fbb29c6cfa9f6e0204a27bfe58bf4ecf1b4/63c85be8/dxysKH9-IRe0fopHnDA9GGf54mxrEpFtdH4pyMm2uqkUclp7t5xT1rW_NQ-wSsohWwsfbUVUDT5YqkHthwEj4g%3D%3D?uid=1070951606&filename=apple-xxhkw-caquk.png&disposition=attachment&hash=&limit=0&content_type=image%2Fpng&owner_uid=1070951606&fsize=675526&hid=a49cfeb39e5819728ee8221f113b4fbd&media_type=image&tknv=v2&etag=0eb79b7987ca12d70612a2c581c6239d When I open the link in my browser and even in incognito mode where I'm not logged in to Yandex, it works. And it also works when I directly put the link in the html without any javascript. But when I try to put the link in the src of an img using javascript I get a 403 not authorized error in the console. Is there a way to fix this or any workarounds? -
Unable to fix Node Path in packaged Electron App
I'm building a simple Electron app for MacOS (using React as the frontend). The purpose of the app was to make executing certain terminal commands a lot easier. Primarily I am interested in using the sfdx Salesforce CLI commands. When I run the app in dev, everything works fine. However when I package the app, the PATH variable gets changed and I'm no longer able to locate the sfdx library. (*note it is still able to find git commands though). I found a very similar issue here and a bug report in GitLab, both of which recommend the use of the fix-path package. This is where I run into another issue. According to the docs, I should import the package like this: import fixPath from 'fix-path'; However when I do that inside of my electron.js file I get this error: SyntaxError: Cannot use import statement outside a module. I've seen other resources that use require to bring in the package: const fixPath = require('fix-path'); But again, when I do that I get this error require() of ES Module not supported. I tried adding "type": "module" to my package.json file, but that breaks my app as well. I feel like there … -

React + django, not being able to render detail view
I'm having some trouble fetching data from my modules when it comes to detail views. Basically I have news that are displayed, and then I want the user to be able to click the news and get to a detail view of that news. The fetching works fine when the url is just localhost/Nyheter (news in swedish) but not when I add an id after (localhost/Nyheter/10). This is the relevant code (I hope). I might be missing something very basic, but I've looked around for a while and it can't make it make sense, thanks in advance! NewsItemPage.js class NewsItem extends Component{ state={ item: {} } id = this.props.params.match.id; async componentDidMount(){ try { const res = await fetch("http://localhost:8000/api/news/"+this.id); const item = await res.json(); console.log(item); this.setState({ item }) }catch(e){ console.log(e); } } App.js function App() { return ( <Router> <Navigation /> <Routes> <Route path="/" element={<Home />}> Hem </Route> <Route path="/Nyheter" element={<News/>}>Nyheter</Route> <Route path="/Nyheter/:id" element={<NewsItemPage/>}>Nyheter-detaljer</Route> <Route path="/om-oss">Om oss</Route> <Route path="/kontakt">Kontakt</Route> </Routes> <Footer /> </Router> ); serializers.py class NewsSerializer(serializers.ModelSerializer): class Meta: model = News fields = '__all__' lookup_field = 'id' views.py @api_view(['GET']) def news_list(request): if request.method == 'GET': data = News.objects.all() serializer = NewsSerializer(data, context={'request': request}, many=True) return Response(serializer.data) urls.py from hemsida import … -
Comparing numbered urls in django template
In urls.py I have: path("viewer/<str:case>", views.viewer, name="viewer"), This works when I go to the viewer: <a class="nav-link dropdown-toggle {% if request.resolver_match.url_name == "viewer" %}active{% endif %}"> Now, there is a menu in nav bar that lists cases. I need to know which specific page I'm on to make one of menu items active: {% for item in cases %} <li> <a class="dropdown-item {% if request.get_full_path == "/viewer/{{ item.id }}" %}active{% endif %}" href="/viewer/{{ item.id }}">{{ item.patient_name }}</a> </li> request.get_full_path returns /viewer/47 for example and one of the items is 47. I've tried different combinations instead of "/viewer/{{ item.id }}, nothing works. -
Extra Cruft in Django URLs
I have a project that is over ten years old. I recently upgraded it to Django 4.1.x. I have a url that looks like this: re_path( r"^author/([a-z-]+)/post/([a-z0-9-]+)/$", research_views.display_article, name="display_article", ), This is what I want to see in the browser's URL bar: http://localhost:8000/author/hank-johnson/post/guam-tips-over/ But if I add extra cruft to the URL it gets displayed and never gets trimmed out of the URL bar. http://localhost:8000/author/hank-johnson/post/guam-tips-over/?---adf That's a problem because Google is now accumulating malformed URLs in its index. How do I ensure that the final "/" is indeed the final slash and no extra cruft can be appended to the URL? -

Django Rest Framework - How can I get the unlimited depth of a specific field in a serializer
I have posts and replies to posts. Replies can have parents unless the reply is the top reply. Like twitter you can reply to a reply and if you click on a reply you can see the reply and the parents of the reply so there is a hierarchy of replies. I have two questions please. ONE: How can I display the hierarchy in an endpoint so it goes as far as the rabbit hole goes? At the moment I only see the reply and then the parent of that reply. I cannot see the parent of the parent of the reply. It stops on the first level upwards? I don't want to make the depth setting to be more than 1, so looking for an alternative way or maybe the better or correct way. Here is my post serializer: class PostSerializer(serializers.ModelSerializer): images = PostImageSerializer(many=True, read_only=True, required=False) profile = serializers.SerializerMethodField() replies = PostRepliesSerializer(many=True, read_only=True, required=False) class Meta: model = Post fields = [ "id", "can_view", "can_comment", "category", "body", "images", "video", "profile", "published", "created_at", "updated_at", "replies", ] depth = 1 def get_profile(self, obj): profile_obj = Profile.objects.get(id=obj.user.profile.id) profile = ShortProfileSerializer(profile_obj) return profile.data def create(self, validated_data): user = User.objects.get(id=self.context['request'].data.get('user')) category = Category.objects.get(id=self.context['request'].data.get('category')) new_post … -
How to change Q from AND to OR - Python with Django

How do I create a ManyToMany field that is based on another field?

Now, I want to add the fields "core_subfeature" and "optional_subfeature" to ProductOrders, but I want to make sure that the user only gets presented optional subfeatures that are available for that Product (core subfeatures will be pre-filled for the user, as these are fixed to a product). I have tried ForeignKey (to Product table) but that requires the fields to be unique across the table I think, but one subfeature can be part of many products, so … -

Selenium thread only works once
I have a dockerized Django app with some threads. Those threads perform periodic tasks, and use Selenium and Beautiful Soup to scrap data and save it to the database. When initializing one thread, the first scrap goes well, data is checked and the function sleeps. However, when the sleep finishes the next scrap isn't performed. This is the thread head code: def thread1(): time_mark = 0 while True: print('Thread1 START') op = funct_scrap(thread1_url) ... sleep(60) The funct_scrap scrapes the web using Selenium, works for the first time but it stops after that. I'd need it to check periodically. In development server works well, but now on Docker there is this problem. What's going on? -
