python - How to force os.system() to use bash instead of shell -


मैंने कोशिश की है 

  os.system ( 'GREPDB = "मेरा आदेश"') os.system ( '/ bin / bash -c \' $ GREPDB \ '')   
 हालांकि कोई भाग्य, दुर्भाग्य से मैं की जरूरत है इस कमांड को bash और subp के साथ चलाने के लिए इस वातावरण में एक विकल्प नहीं है, मैं अजगर 2.4 तक सीमित हूं। सही दिशा में मुझे पाने के लिए कोई भी सुझाव?   
 
 
 दोनों कमांड विभिन्न subshells में निष्पादित हैं।  
 पहले  सिस्टम  कॉल में चर को सेट करना दूसरे  सिस्टम  कॉल को प्रभावित नहीं करता है।  
 आपको एक कमांड को एक स्ट्रिंग (;  के साथ संयोजन करके) डालनी होगी।  
  & gt; & gt; & gt; आयात ओएस & gt; & gt; & gt; 123 0   
  नोट  आप उपयोग करने की आवश्यकता <; os.system ( '-c "$ GREPDB" / bin / bash GREPDB = "गूंज 123"') कोड> "$ GREPDB"  के बजाय  '$ GREPDBS'  के बजाय अन्यथा इसे विस्तारित होने के बजाय शब्दशः व्याख्या की जाती है।  
 यदि आप  उपप्रोसेस :  
 > gt; & gt; & gt; आयात उपप्रक्रिया & gt; & gt; & gt; 123 0

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.

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...
