    PHP में स्थिरांक के साथ समस्याएं सोच रहा है कि कोई ये समझा सकता है:

    यह कार्य 

      const _ROOT = 'd: / aphp / www'; गूंज "आर =" ._ रूट;   
     ऐसा करता है:  
      यदि (सत्य) परिभाषित करें ('_ रूट', 'डी: / एपीपी / www'); गूंज "आर =" ._ रूट;   
     लेकिन यह त्रुटि देता है: पार्स त्रुटि: वाक्यविन्यास त्रुटि, अप्रत्याशित T_CONST  
      यदि (सही) const _ROOT = 'd: / aphp / www' ; गूंज "आर =" ._ रूट;   
     मैं PHP 5.3.2 का उपयोग कर रहा हूं   
     
     
     इसका कारण यह है 
      
     नोट  
      
      
     : परिभाषित () परिभाषित करने वाले विरोधियों को परिभाषित करने के विरोध में, कस्ट कीवर्ड का उपयोग करके परिभाषित स्थिरांक को शीर्ष-स्तरीय दायरे में घोषित किया जाना चाहिए क्योंकि इन्हें संकलित समय पर परिभाषित किया गया है। इसका मतलब है कि उन्हें कार्य, छोरों या बयान में घोषित नहीं किया जा सकता है।

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

matlab - Using loops to get multiple values into a cell -

I have 31 topics (S1, S2, S3, S4, etc.) 3 images in each topic, opposite 1 IMG, Contrast 2 IMG and Contrast 3 Are IMG I p In a NX1 cell named P, I would like to use a loop to get all the paths of contrasts from all the subjects: data / S1 / contrast1.img / S1 / contrast2.img data / S1 / contrast3.img data / s2 / contrast1.img data / S2 / contrast2.img Data / S2 / contrast3.img ... Data / S31 / contast3.img This is what I've tried: A = {'S1', 'S2', 'S3', ..., 'S31'}; % All topics C = {'contrast1.img', 'contrast2.img', 'contrast3.img'}; For each = P = cell (31 * 3,1) for each topic, the required contrast images: Length = A for Jammu = 1: Length (C) P {j} = spm_select ('FPList', Fullfile (data_path, q {i}) sprint ('% s', cell2mat (c))); % Of each topic is to select three contrast images, it works in my script, it is probably not 100% correct, because I had to simplify this example. End of ...

python - Sequence Pattern recognition with Pybrain -

Image
I am constantly trying to use recurrent neural networks to classify a series of data. To be more specific, I have a sequence of sensor reading (which is continuous over time), I have to learn an algorithm which can detect the state related to this pattern, given the readings change. Example: Time step_1: 1.4 Time step_2: 1 Time step_3: 0.8 State = New Sequence: Time Phase 1: 0.4 Time Phase 2: 0.3 Time Phase 3: 0.1 State = Sitting I actually have 12 censors, I'm just showing a sequence of numbers for convenience. (Numbers are not real, I'm just trying to fulfill this idea)! I am trying to make my network with PyBrain RNN, however, I can not get a Data Set Container that can detect it, like information I tried to use sequential data But after some testing I came to know that this number is the next element in the sequence of numbers. Here's how I prepare my dataset: self.alldata = SequentialDataSet (ds.num_features, 1) # Now add samples to the dat...
