php - Download size is not specified -


मैं एक पीडीएफ फाइल डाउनलोड करना चाहता हूं: 

  $ output = RP_MAIN 'डॉकबुक / डेटा / मायफ़ाइल' $ _SESSION ["sess_code_user"] '.pdf'; // यह पीडीएफ फाइल है, मैं $ file_size = filesize ($ आउटपुट) डाउनलोड करना चाहता हूं; शीर्षलेख ("प्रागमा: सार्वजनिक"); शीर्षलेख ("समाप्ति: 0"); हैडर ("कैश-कंट्रोल: आवश्यक-संशोधित, पोस्ट चेक = 0, प्री-चेक = 0"); शीर्ष लेख ("सामग्री-प्रकार: पाठ / समृद्ध"); शीर्ष लेख ("सामग्री-लंबाई: $ file_size"); हेडर ('सामग्री-विवाद: अनुलग्नक; फाइलनाम =' '।' मैनुअल। '$ एक्सटेंशन।' '।' '' '); ob_clean (); फ्लश (); प्रिंट ($ उत्पादन); बाहर जाएं();   
 पीडीएफ फाइल सिस्टम में मौजूद है और इसमें 25 केबी आकार का है। लेकिन समस्या यह है कि डाउनलोड पॉपअप (इंटरनेट डाउनलोड प्रबंधक) के आकार के क्षेत्र में रिक्त फ़ील्ड है।  
 मेरे कोड में क्या गलत है? मैं इस मुद्दे को कैसे हल कर सकता हूं?  
 
  संपादित करें:  एजेक्स कॉल से पीडीएफ फाइल बनाई गई है, फिर एजेक्स की सफलता पर डाउनलोड शुरू हो गया है: < / P> 
  var request = $ .ajax ({डेटा: donne, टाइप करें: "POST", url: "& lt;? Php echo HTTP_AJAX_TACHE? & Gt; TacheCreerPdfAjax.php", // यह पीडीएफ बनाता है फ़ाइल async: false}); Request.done (function () {$ ('# corps')। Html (request.responseText); अगर (fichier == "pdf" = fichier == "rtf") window.location.href = '& lt ;? Php echo PAGE_TACHE? & Gt;? Action = TacheGenererManuelExec & amp; fichier = '+ fichier; // यह डाउनलोड शुरू करता है ...}   
 इसलिए डाउनलोड शुरू करते समय एक त्रुटि कहती है कि स्रोत का प्रारूप पीडीएफ नहीं है!   
 
 
 इसे चेक करें:  
  $ Output = RP_MAIN। 'Docbook / data / myfile'। $ _SESSION ["sess_code_user"]। '.pdf'; यदि (is_file ($ आउटपुट)) {$ size = filesize ($ आउटपुट); यदि (function_exists ('mime_content_type ') $ $ Type = mime_content_type ($ output);} अन्यथा (function_exists (' finfo_file ')) {$ info = finfo_open (FILEINFO_MIME); $ type = finfo_file ($ info, $ आउटपुट); finfo_close ($ info); } अगर ($ प्रकार == '') {$ type = "application / force-download";} शीर्षलेख ("सामग्री-प्रकार: $ प्रकार"); शीर्षलेख ("सामग्री-विवाद: अनुलग्नक; फ़ाइल नाम = $ नाम") ; हेडर ("कंटेंट-ट्रांसफर एन्कोडिंग: बाइनरी"); एच ईडर ("कंटेंट-लम्बाई:" $ आकार); readfile ($ उत्पादन); बाहर जाएं; } अन्य {वापसी झूठी; }

c - Performance of System() -

After the function in C, for the system (), it affects the hardware counters, so how do you order that The example displayed for the example you are trying to view lets the IM use the display API (PAPI) and the program is a precompiled matrix multiplication application. PAPI_start_counters (); System ("./matmul"); PAPI_read_counters (); // Print the values ​​PAPI_stop_counters (); I'm clearly missing a bit, but I'm trying to figure out what it is possible to say, counter receiving a program im running Is through use. With my tests I will get wild numbers like below, they are clearly wrong, just want to find out why total bicycle =========== 140733358872510 instructions complete =========== 4203968 Floating Point Instructions =========== Floating Point Operations =========== 4,196,867 Weight ======= ==== 140733358872804 store ======= ==== 4204037 branches taken =========== 15774436 System () Normally it is a very slow function, on Linux, it is ...

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:...

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...
