PIX Call that Previously Succeeded Failed During Playback error on IASetVertexBuffers() - directx
I'm trying to debug the shaders in a SlimDX DirectX11 game I've been coding for a while. The code runs fine and executes without a hitch (albeit seemingly ignoring my textures) and when I run an experiment to capture a single frame inside PIX it executes fine, however if I try to access either the Render or Mesh tabs in PIX for my captured frame I get the following error:
A call that previously succeeded failed during playback:
EID: 96
Call: ID3D11DeviceContext::IASetVertexBuffers()
HRESULT: E_FAIL
The EID is one that occurs just before the frame I've captured (my frame starts at EID 108) so I can't see where it's failing.
I decided to run a full stream of frames to see if that would show me the error. This time I got something useful.
A call that previously succeeded failed during playback:
EID: 15
Call: IDXGISwapChain::GetParent()
HRESULT:E_FAIL
And the event log that caused it:

There's nothing in the output log either. Has anybody encountered this before? If so how did you fix it?
Although the reply may not be needed any longer or may differ from the cause of your problem, I at least was troubled by the IASetVertexBuffers() error problem of PIX similar to it.
The cause in my case was having disposed of the buffer which remains bound as a Vertex buffer.
The error has been avoided when the original buffer was disposed of after it, after binding null to the Vertex buffer.
// Create Buffer
buffer = new SlimDX.Direct3D11.Buffer(device, stream, vertexBufferDesc);
stream.Dispose();
// Bind
device.ImmediateContext.InputAssembler.SetVertexBuffers(0, new VertexBufferBinding(buffer, stride, 0));
// Draw
effectPass.Apply(device.ImmediateContext);
device.ImmediateContext.Draw(primitiveCount, 0);
// Unbind and Dispose
device.ImmediateContext.InputAssembler.SetVertexBuffers(0, new VertexBufferBinding(null, 0, 0));
buffer.Dispose();
I encountered those errors before, whenever I was using stream output with the vertex shader (not sure if with geometry shader also). There was no fix for it.
Depending on what GPU you have, try debugging your application with AMDs GPU PerfStudio or Nvidias Parallel Nsight. Maybe it will work in them.

SVG stroke gradient causes horizontal lines to display on iOS Safari
Adding a radial gradient to my SVG path seems to cause weird horizontal (anti-aliasing?) lines on some iOS devices or when you zoom in/out on an iOS device. I wasn't able to replicate it anywhere else. Here's the (isolated) code: <svg class="componentClass__chart-svg" width="335" height="318" viewBox="0 0 335 320" xmlns="http://www.w3.org/2000/svg"> <defs> <radialGradient id="axesGradient" cx="50%" cy="0%" fx="50%" fy="0%" r="50%"> <stop stop-color="#FFFFFF" offset="10%"></stop> <stop stop-color="#FFFFFF" offset="100%" stop-opacity="0.2"></stop> </radialGradient> </defs> <path class="componentClass__axes" stroke-width="2" stroke="url(#axesGradient)" fill="none" d="M151 12 Q167 0 183 12 L319 108 Q335 120 329 139 L276 299 Q270 318 250 318 L85 318 Q65 318 59 299 L6 139 Q0 120 16 108 Z M151 37 Q167 25 183 37 L293 116 Q309 128 303 147 L260 275 Q254 294 234 294 L101 294 Q81 294 75 275 L32 147 Q26 128 42 116 Z M151 62 Q167 50 183 62 L267 124 Q283 136 277 155 L244 251 Q238 270 218 270 L117 270 Q97 270 91 251 L58 155 Q52 136 68 124 Z M151 87 Q167 75 183 87 L241 132 Q257 144 251 163 L228 227 Q222 246 202 246 L133 246 Q113 246 107 227 L84 163 Q78 144 94 132 Z M152 113 Q167 100 183 113 L215 139 Q231 152 224 171 L213 203 Q206 222 186 222 L149 222 Q129 222 122 203 L111 171 Q104 152 119 139 Z " /> </svg> And the issue: SVG showing horizontal line Note this doesn't happen on every iPhone or iPad, but you're usually able to replicate it when you try zooming in and out. I was able to nail down the issue to this particular use case: as soon as you add the gradient to the stroke, it starts happening. If you change stroke="url(#axesGradient) to just stroke="#FFF", it doesn't seem to happen. Is there any way I can optimize the SVG to prevent rendering issues? Here's a Codepen with the exact code above.
Had the same problem, but in my case these lines appeared in any browser on IOS 16, updating to IOS 16.3 fixed it
Export datas from mongodb using mongoexport from a specific time range with query and timestamp
I'm trying to export a collection from mongodb using mongoexport. This works so far:
mongoexport.exe --db dataloggin --collection p1 --out myRecords.json
The problem is that the file is huge and I can not open it anymore (araound 20GB, 30 days, every half a second a document).
I just need the data between the 3. March and the 5 March, so I tried to select this date range with the query selector as following:
mongoexport.exe --db dataloggin --collection p1 -q='{"timestamp":{"$gte":{"$timestamp":"2016-03-3T00:00:00.000Z"}:},"timestamp":{"$lt":{"$timestamp":"2016-03-05T00:00:00.000Z"}}}' --out myRecords.json
But I get an error:
error validating settings: query '[39 123 116 105 109 101 115 116 97 109 112 58 123 36 103 116 101 58 123 36 116 105 109 101 115 116 97 109 112 58 50 48 49 54 45 48 49 45 48 49 84 48 48 58 48 48 58 48 48 46 48 48 48 90 125 58 125 44 116 105 109 101 115 116 97 109 112 58 123 36 108 116 58 123 36 116 105 109 101 115 116 97 109 112 58 50 48 49 54 45 48 49 45 48 49 84 48 48 58 48 48 58 48 48 46 48 48 48 90 125 125 125 39]' is not valid JSON: json: cannot unmarshal string into Go value of type map[string]interface {}
Someone have an idea?
Many Thanks and regards
How to overcome with this error when using Networkx's kernighan_lin_bisection
I want to use kernighan_lin_bisection from Networkx to separate a network data.
But the error below showed up and I'm stuck.
It would be highly appreciated if you could help me overcome this error.

You've got for c in init_partition: for n in c: color_map_i[n]=colors[counter] counter=counter+1 It looks to me like n will loop over all of the nodes of the graph. I do not see any entries in the graph that are 0. So probably the nodes are numbered 1 to N, while color_map_i is indexed from 0 to N-1. So it would break when n=N. A good way to hunt for bugs like this in general would be to print n right before the line giving the error. This would give a hint to what the problem is.
Why does calcHist in Opencv produce 0 array in output?
I do hist calculation using OpenCV. I have the following implementation.
//Check image
for (int i = 0; i < block.rows; i++)
{
unsigned char *ptr = block.ptr<unsigned char>(i);
for (int j = 0; j < block.cols; j++)
{
cout << (int)ptr[j] << " ";
}
cout << endl;
}
//That gave

So pixel values are there.
//Histogram calculation
int histbin = 128;//quantize
int histSize[] = { histbin };
float range[] = { 0, 255 };
const float *ranges[] = { range };
Mat hist;
int channels[] = { 0};
calcHist(&block, 1, channels, Mat(), hist, 1, histSize, ranges, true, false);
//Print output
for (int h = 0; h < histbin; h++)
{
float binVal = hist.at<float>(h);
cout << " " << binVal;
}
I have outputs as follow.

What is wrong with my implementation?
Convert PNG images to pixel gray-level values feature vectors
I am a newbie in MATLAB and I have a set of bmp images which I need to convert into pixel gray-level values as feature vectors of image. Can anyone suggest me the way how I can do that? I need to use these pixel gray-level values as features and then perform operations like PCA/LDA. I tried imread() but it returns me a matrix.. I feel feature vector will be just one row vector. Regards,
imread() is the correct way to do it. Then just convert from a matrix into a vector. For example: >> X = randi(255, 10) X = 208 41 168 181 112 71 192 215 90 20 231 248 10 9 98 174 66 65 212 14 33 245 217 71 196 168 130 208 150 136 233 124 239 12 203 42 179 63 141 199 162 205 174 25 48 31 228 237 234 239 25 37 194 210 125 128 245 90 73 34 72 108 190 178 114 245 140 51 194 146 140 234 101 81 165 87 36 65 193 120 245 203 168 243 181 150 39 158 98 4 247 245 44 9 193 58 66 121 145 86 >> X(:) ans = 208 231 33 233 162 25 72 140 245 247 ... Then you can just stack your different observations together with [] and do PCA.
