which I deem bad to catastrophal, if I want to run it on a low-performance-device such as an old Raspberry PI.
However I fail to find the answers to: what to make out of this? How can I improve it, to reduce the amount of batches, especially the Alpha-batches?
I have only few objects (2) with opacity != 0 and at the time of this output all of them have been set to invisible.
I have two SVGs (8 nodes each) which might show up there.
I do not use any colors that would not fit in the format '#------ff' (unless the svg-colors of which I use a few might have the alpha-channel set otherwise) and do not use the color 'transparent'
I do have an object that consists out of two "concentric" Rectangles of opaque color, that are marked unmerged when visualizing the overdraw, which I have no clue, why. At least it could be merged with it's not-intersecting siblings, I deem. Why wouldn't they?
I think it migh help if I might identify the objects, but when I ouput the adresses of any object that is visible, (Component.onCompleted: console.log(this)) I do not get any of the listed adresses.
How might I achieve a mapping between the render-objects and my QML-Objects?
And - What doe all those list entries mean at all?
EDIT: It seems, I used some PNG's with alpha enabled. Replacing them with JPG reduced the message to this. But those were only 5 of the nodes/batches. 34 to go...
-> Opaque: 43 nodes in 6 batches...
-> Alpha: 29 nodes in 8 batches...
Greetings & Thanks,

From doc.qt.io: "[one batch] is created for each unique set of material state and geometry type". Reduce the number of differences and the default renderer puts compatible OpenGL primitives into the same batch.
For example:
Rectangle elements with different width/height/color/gradient/rotation properties are batched together but with different opacity/radius/antialiasing properties are not.
Rectangle elements with the color property set to an opaque value using hexadecimal triplets (Ex.: specifying 'forestgreen' with '#228B22' or '#282') are batched together. But specifying translucent colors (a hex quad that does not start with '#FF', ex.: '#44228B22' -- 25% opaque 'forestgreen') forces a separate batch even if the translucent color values are identical (verified on Qt 5.9.1). Having translucent border colors also forces separate batches even if the translucent color values are identical.
Text elements with different font letterspacing/underline
properties are grouped together, but different font bold/italic/pixelSize/hintingPreference properties are separated.
You can determine which objects are which by changing the visible property and seeing what appears or disappears.

I've one master(x.x.x.61), one volume(x.x.x.63) and one filer + s3API (x.x.x.62) setup on 3 separate machines.
I added a new volume server (x.x.x.64) because I've max out the storage space on the first volume server.
But I'm still not able to add new files on the filer UI(http://x.x.x.62:8888)
In my filer logs, I noticed that it's trying to connect to the first volume server IP address that's out of space. Am I missing a configuration for it to connect to the new volume server?

I am searching for a way to use the GAP System to find a solution of a linear Diophantine equation over the non-negative integers. Explicitly, I have a list L of positive integers for each of which there exists a solution of the linear Diophantine equation s = 11*a + 7*b such that a and b are non-negative integers. I would like to have the GAP System return for each element s of L the ordered pair(s) [a, b] corresponding to the above solution(s).
I am familiar already with the command SolutionIntMat in the GAP System; however, this produces only some solution of the linear Diophantine equation s = 11*a + 7*b. Particularly, it is possible (and far more likely) that one of the coefficients a and b is negative. For instance, I obtain the solution [-375, 600] when I use the aforementioned command on the linear Diophantine equation 75 = 11*a + 7*b.
For additional context, this query arises when working with numerical semigroups generated by generalized arithmetic sequences. Use the command LoadPackage("numericalsgps"); to implement computations with such objects. For instance, if S := NumericalSemigroup(11, 29, 36, 43, 50, 57, 64, 71);, then each of the minimal generators of S other than 11 is of the form 2*11 + 7*i for some integer i in [1..7]. One can ask the GAP System for the SmallElements(S);, and the GAP System will return all elements of S up to FrobeniusNumber(S) + 1. Clearly, every element of S is of the form 11*a + 7*b for some non-negative integers a and b; I would like to investigate what coefficients a and b arise. In fact, the answer is known (cf. Proposition 2.5 of this paper); I am just trying to get an understanding of the intuition behind the proof.
Thank you in advance for your time and consideration.
Dylan, thank you for your query and for using GAP and numericalsgps.
You can probably use in this setting Factorizations from the package numericalsgps. It internally rewrites the output of RestrictedPartitions.
For instance, in your example, you can get all possible "factorizations" of the small elements of S, with respect to the generators of S, by typing List(SmallElements(S), x->[x,Factorizations(x,S)]). A particular example:
gap> Factorizations(104,S);
[ [ 1, 0, 0, 1, 1, 0, 0, 0 ], [ 1, 0, 1, 0, 0, 1, 0, 0 ],
[ 1, 1, 0, 0, 0, 0, 1, 0 ], [ 3, 0, 0, 0, 0, 0, 0, 1 ] ]
If you want to see the factorizations of the elements of S in terms of 11 and 7, then you can do the following:
gap> FactorizationsIntegerWRTList(29,[11,7]);
[ [ 2, 1 ] ]
So, for all minimal generators of S you would do
gap> List(MinimalGenerators(S), g-> FactorizationsIntegerWRTList(g,[11,7]));
[ [ [ 1, 0 ] ], [ [ 2, 1 ] ], [ [ 2, 2 ] ], [ [ 2, 3 ] ],
[ [ 2, 4 ] ], [ [ 2, 5 ] ], [ [ 2, 6 ] ], [ [ 2, 7 ] ] ]
For the set of small elements of S, try List(SmallElements(S), g-> FactorizationsIntegerWRTList(g,[11,7])). If you only want up to some integer, just replace SmallElements(S) with Intersection([1..200], S); or if you want the first, say 200, elements of S, use S{[1..200]}.
You may want to have a look at Chapter 9 of the manual, and in particular to FactorizationsElementListWRTNumericalSemigroup.
I hope this helps.
I have a matrix [3,3,256], my final output must be [4,2,2,256], I have to use a reshape like a 'convolution' without changing the values. (In this case using a filter 2x2). Is there a method to do this using tensorflow?
If I understand your question correctly, you want to store the original values redundantly in the new structure, like this (without the last dim of 256):
[ [ 1 2 3 ] [ [ 1 2 ] [ [ 2 3 ] [ [ 4 5 ] [ [ 5 6 ]
[ 4 5 6 ] => [ 4 5 ] ], [ 5 6 ] ], [ 7 8 ] ], [ 8 9 ] ]
[ 7 8 9 ] ]
If yes, you can use indexing, like this, with x being the original tensor, and then stack them:
x2 = []
for i in xrange( 2 ):
for j in xrange( 2 ):
x2.append( x[ i : i + 2, j : j + 2, : ] )
y = tf.stack( x2, axis = 0 )
Based on your comment, if you really want to avoid using any loops, you might utilize the tf.extract_image_patches, like below (tested code) but you should run some tests because this might actually be much worse than the above in terms of efficiency and perfomance:
import tensorflow as tf
sess = tf.Session()
x = tf.constant( [ [ [ 1, -1 ], [ 2, -2 ], [ 3, -3 ] ],
[ [ 4, -4 ], [ 5, -5 ], [ 6, -6 ] ],
[ [ 7, -7 ], [ 8, -8 ], [ 9, -9 ] ] ] )
xT = tf.transpose( x, perm = [ 2, 0, 1 ] ) # have to put channel dim as batch for tf.extract_image_patches
xTE = tf.expand_dims( xT, axis = -1 ) # extend dims to have fake channel dim
xP = tf.extract_image_patches( xTE, ksizes = [ 1, 2, 2, 1 ],
strides = [ 1, 1, 1, 1 ], rates = [ 1, 1, 1, 1 ], padding = "VALID" )
y = tf.transpose( xP, perm = [ 3, 1, 2, 0 ] ) # move dims back to original and new dim up front
print( sess.run(y) )
Output (horizontal separator lines added manually for readability):
[[[[ 1 -1]
[ 2 -2]]
[[ 4 -4]
[ 5 -5]]]
[[[ 2 -2]
[ 3 -3]]
[[ 5 -5]
[ 6 -6]]]
[[[ 4 -4]
[ 5 -5]]
[[ 7 -7]
[ 8 -8]]]
[[[ 5 -5]
[ 6 -6]]
[[ 8 -8]
[ 9 -9]]]]
I have a similar problem with you and I found that in tf.contrib.kfac.utils there is a function called extract_convolution_patches. Suppose you have a tensor X with shape (1, 3, 3, 256) where the initial 1 marks batch size, you can call
Y = tf.contrib.kfac.utils.extract_convolution_patches(X, (2, 2, 256, 1), padding='VALID')
Y.shape # (1, 2, 2, 2, 2, 256)
The first two 2's will be the number of your output filters (makes up the 4 in your description). The latter two 2's will be the shape of the filters. You can then call
Y = tf.reshape(Y, [4,2,2,256])
to get your final result.
With ncsim the following code throws the error:
Bit-select or part-select index out of declared bounds.
However, the commented out code which does exactly the same thing doesn't. Am I missing something or is the compiler mistaken?
module pd__test;
genvar i, j;
reg [10-1:0] assign_from_reg;
reg [256:0] assign_to_reg;
generate
for (i=0; i<2; i=i+1) begin
for (j=0; j<13; j=j+1) begin
always #* begin
if (i+2*j < 25) begin
// gives me an index out of bounds error
assign_to_reg[10*(i+2*j)+9 : 10*(i+2*j)] = assign_from_reg;
// gives me no such error, however the indices are the same
// assign_to_reg[10*(i+2*j)+9 -: 10] = assign_from_reg;
end else begin
// do something else
end
end
end
end
endgenerate
endmodule
I ran a python script to print the indeces to double check:
for i in range(2):
for j in range(13):
if (i+(2*j) < 25):
print("[", 10*(i+(2*j))+9, ":", 10*(i+(2*j)), "]")
Prints:
[ 9 : 0 ]
[ 29 : 20 ]

you asked verilog compiler to compile this code in the always block
assign_to_reg[10*(i+2*j)+9 -: 10]
which for i == 1 and j == 12 is generated by the generate block as:
assign_to_reg[259 : 250]
The above is clearly outside of the declared bounds [256:0].
Moving the 'if' into the generate block, as #toolic suggested would cause verilog not to generate the last always block at all, therefore, it will not be compiled and no warning/error would be produced.
So, the other solution with generate blocks would be to declare your assign_to_reg as [259:0].
And yet the best solution would be to get rid of the generate block all together and move all your loops inside the single always block:
always #* begin
for (int i=0; i<2; i=i+1) begin
for (int j=0; j<13; j=j+1) begin
if (i+2*j < 25) begin
assign_to_reg[10*(i+2*j)+9 -: 10] = assign_from_reg;
end
end
end
end
This should let compiler to calculate indexes at run-time and will not cause out-of-bound access as well.
Move the conditional if (i+2*j < 25) outside of the always block:
module pd__test;
genvar i, j;
reg [10-1:0] assign_from_reg;
reg [256:0] assign_to_reg;
generate
for (i=0; i<2; i=i+1) begin
for (j=0; j<13; j=j+1) begin
if (i+2*j < 25) begin
always #* begin
//assign_to_reg[10*(i+2*j)+9 : 10*(i+2*j)] = assign_from_reg;
assign_to_reg[10*(i+2*j)+9 -: 10] = assign_from_reg;
end
end
end
end
endgenerate
endmodule
Both assignments compile without warnings or errors for me.
For learning purpose i have build openstack on VirtualBox with 2 vCPU and 4GB Memory. It installed successfully and i am able to start VM instances but what happened is guest VM got SHUTOFF status after few minutes. I have google this issue but didn't get proper answer. I have check logs and i didn't find anything suspicious.
How do i check VM console so i can see what is going on there?
Where should i check SHUTOFF specific error logs, i meant in which file?

You can get guest console on the dashboard or with this command:
nova get-vnc-console <instance id> novnc
If your guest image redirects console messages (like the ubuntu cloud image), you can see boot messages on dashboard or with the command:
nova console-log <instance id>
You may get clues in /var/log/nova/nova-compute.log and in your hypervisor logs (/var/log/libvirt/libvirtd.log for QEMU/KVM).
A possible cause is that your guest can't boot on its primary disk and get stuck on boot sequence. Try other images, like the ones proposed in OpenStack documentation.
