I'm using D3 to markup X3Dom as in this example: http://bl.ocks.org/jbeuckm/5620882
I converted the example to use simple squares instead of boxes: http://bl.ocks.org/jbeuckm/5645205
In a later version, I started loading data and calling plotAxis and plotData from various callbacks. It works as expected if I draw boxes as in the first example:
shape.append("x3d:box");
But when I substitute my 2-triangle face set...
shape.append("x3d:indexedFaceSet")
.attr("coordIndex", "0 1 2 -1 2 3 0 -1")
.attr('solid', 'false')
.append("x3d:coordinate")
.attr("point", "-1 -1 0, 1 -1 0, 1 1 0, -1 1 0")
it doesn't work and I get this error:
Uncaught TypeError: Cannot call method 'getPoints' of null

It looks like maybe the "node-inserted" code analyzes the shape before the <Coordinate> child has been added to the <IndexedFaceSet>. But, I'm not sure why the same append statement would work in one context and not another. Again, just appending an x3d:box works fine in my data-loading setup, but the x3d:indexedFaceSet throws the error.
A workaround is to build up the IndexedFaceSet node separately, then generate the markup string for the node, then use D3's selection.html(str) to append the node to the shape. In the code referenced above, "shape" is a selection of data-bound nodes, so the workaround is like this:
shape.each(function(d){
var newNode = "<indexedFaceSet coordIndex="..."><coordinate point="..."/></indexedFaceSet>";
d3.select(this).html(newNode);
});

I'm working on a deep learning model and I would like to be able to display images on Tensorboard to have the input, the ground truth and the prediction side by side.
Currently, the display look like this :
current display
But this visualization is not convenient, because it's not easy to compare the ground truth with the prediction if images are not side by side, and we have to scroll to pass from the ground truth to the prediction (because images are too big and we display more than 6 images).
The current code :
for epoch in range(EPOCHS):
for step, (x_train, y_train) in enumerate(train_ds):
y_, gloss, dloss = pix2pix.train_step(x_train, y_train, epoch)
if step%PRINT_STEP == 0:
template = 'Epoch {} {}%, G-Loss: {}, D-Loss: {}'
print (template.format(epoch+1,int(100*step/max_steps),gloss, dloss))
with train_writer.as_default():
tf.summary.image('GT', y_train+0.5, step=epoch*max_steps+step, max_outputs=3, description=None)
tf.summary.image('pred', y_+0.5, step=epoch*max_steps+step, max_outputs=3, description=None)
tf.summary.image('input', x_train+0.5, step=epoch*max_steps+step, max_outputs=3, description=None)
tf.summary.scalar('generator loss', gloss, step = epoch*max_steps+step)
tf.summary.scalar('discriminator loss', dloss, step = epoch*max_steps+step)
tf.summary.flush()
So here is an example that what I would like to have :
desired display
I thought about an other solution : save all triples images(input/truth/pred) in local folders (folders 1 : input 1 /truth 1 /pred 1, folders 2 : input 2 /truth 2 /pred 2 ...) and display them with a python library (cv2, matplotlib ...) but same problem, I don't know how to do that if it's possible.
Thanks for your help
I'm working on a ruamel.yaml (v0.17.4) based YAML reformatter (using the RoundTrip variant to preserve comments).
I want to allow a mix of block- and flow-style maps, but in some cases, I want to convert a flow-style map to use block-style.
In particular, if the flow-style map would be longer than the max line length^, I want to convert that to a block-style map instead of wrapping the line somewhere in the middle of the flow-style map.
^ By "max line length" I mean the best_width that I configure by setting something like yaml.width = 120 where yaml is a ruamel.yaml.YAML instance.
What should I extend to achieve this? The emitter is where the line-length gets calculated so wrapping can occur, but I suspect that is too late to convert between block- and flow-style. I'm also concerned about losing comments when I switch the styles. Here are some possible extension points, can you give me a pointer on where I'm most likely to have success with this?
Emitter.expect_flow_mapping() probably too late for converting flow->block
Serializer.serialize_node() probably too late as it consults node.flow_style
RoundTripRepresenter.represent_mapping() maybe? but this has no idea about line length
I could also walk the data before calling yaml.dump(), but this has no idea about line length.
So, where should I and where can I adjust the flow_style whether a flow-style map would trigger line wrapping?
What I think the most accurate approach is when you encounter a flow-style mapping in the dumping process is to first try to emit it to a buffer and then get the length of the buffer and if that combined with the column that you are in, actually emit block-style.
Any attempt to guesstimate the length of the output without actually trying to write that part of a tree is going to be hard, if not impossible to do without doing the actual emit. Among other things the dumping process actually dumps scalars and reads them back to make sure no quoting needs to be forced (e.g. when you dump a string that reads back like a date). It also handles single key-value pairs in a list in a special way ( [1, a: 42, 3] instead of the more verbose [1, {a: 42}, 3]. So a simple calculation of the length of the scalars that are the keys and values and separating comma, colon and spaces is not going to be precise.
A different approach is to dump your data with a large line width and parse the output and make a set of line numbers for which the line is too long according to the width that you actually want to use. After loading that output back you can walk over the data structure recursively, inspect the .lc attribute to determine the line number on which a flow style mapping (or sequence) started and if that line number is in the set you built beforehand change the mapping to block style. If you have nested flow-style collections, you might have to repeat this process.
If you run the following, the initial dumped value for quote will be on one line.
The change_to_block method as presented changes all mappings/sequences that are too long
that are on one line.

dfGDP_percapita.sort_values("Item", axis = 0, ascending = True, inplace = True, na_position ='first')

Some of the arguments are by default - I'm not sure why the error occurs, but my code works like this.
I have a postscript file when i try to convert it into pdf or open it with postscript it gives the following error
undefined in execform
I am trying to fix this error. But there is no solution i found. Kindly Help me understand the issue.
This is postscript file
OK so a few observations to start;
The file is 8 pages long, uses many forms, and the first form it uses has nested forms. This really isn't suitable as an example file, you are expecting other programmers to dig through a lot of extraneous cruft to help you out. When you post an example, please try and reduce it to just the minimum required to reproduce the problem.
Have you actually tried to debug this problem yourself ? If so what did you do ? (and why didn't you start by reducing the file complexity ?)
I don't want to be offensive, but this is the third rather naive posting you've made recently, do you have much experience of PostScript programming ? Has anyone offered you any training in the language ? It appears you are working on behalf of a commercial organisation, you should talk to your line manager and try and arrange some training if you haven't already been given some.
The PostScript program does not give the error you stated
undefined in execform
In fact the error is a Ghostscript-specific error message:
Error: /undefined in --.execform1--
So that's the .execform1 operator (note the leading '.' to indicate a Ghostscript internal operator). That's only important because firstly its important to accurately quote error messages, and secondly because, for someone familiar with Ghostscript, it tells you that the error occurs while executing the form PaintProc, not while executing the execform operator.
After considerably reducing of the complexity of the file, the problem is absolutely nothing to do with the use of Forms. The offending Form executes code like this:
2 RM
0.459396 w
[(\0\1\0\2)]435.529999 -791.02002 T
(That's the first occurrence, and its where the error occurs)
That executes the procedure named T which is defined as:
/T{neg _LY add /_y ed _LX add /_x ed/_BLSY _y _BLY sub D/_BLX _x D/_BLY _y D _x _y TT}bd
Obviously that's using a number of other functions defined in the prolog, but the important point is that it executes TT which is defined as :
/TT{/_y ed/_x ed/_SX _x _LX sub D/_SY _y _LY sub D/_LX _x D/_LY _y D _x _y m 0 _rm eq{ dup type/stringtype eq{show}{{ dup type /stringtype eq{show}{ 0 rmoveto}?}forall}?} if
1 _rm eq {gsave 0 _scs eq { _sr setgray}if 1 _scs eq { _sr _sg _sb setrgbcolor}if 2 _scs eq { _sr _sg _sb _sk setcmykcolor} if dup type/stringtype eq{true charpath }{{dup type /stringtype eq{true charpath } { 0 rmoveto}?}forall}? S grestore} if
2 _rm eq {gsave 0 _fcs eq { _fr setgray}if 1 _fcs eq { _fr _fg _fb setrgbcolor}if 2 _fcs eq { _fr _fg _fb _fk setcmykcolor} if dup type/stringtype eq{true charpath }{{dup type /stringtype eq{true charpath } { 0 rmoveto}?}
forall}? gsave fill grestore 0 _scs eq { _sr setgray}if 1 _scs eq { _sr _sg _sb setrgbcolor}if 2 _scs eq { _sr _sg _sb _sk setcmykcolor}if S grestore} if
Under the conditions holding at the time TT is executed (RM sets _rm to 2), we go through this piece of code:
gsave 0 _fcs eq
However, _fcs is initially undefined, and only defined when the /fcs function is executed. Your program never executes /fcs so _fcs is undefined, leading to the error.
Is there a reason why you are defining each page in a PostScript Form ? This is not optimal, if the interpreter actually supports Forms then you are using up VM for no useful purpose (since you only execute each Form once).
If its because the original PDF input uses PDF Form XObjects I would recommend that you don't try and reproduce those in PostScript. Reuse of Form XObjects in PDF is rather rare (it does happen but non-reuse is much more common). The loss of efficiency due to describing PostScript Forms for each PDF Form XObject for all the files where the form isn't reused exceeds the benefit for the rare cases where it would actually be valuable.
i'm trying to move an object along the points of a complex curved path with a constant velocity using transitions.
I have two tables to keep the coordinates of the points and another table with the respective time intervals for travelling each linear segment at the same speed (despite they have different lengths).
Assuming the firts and last values of the "timeTable" are 0, i tried with something similar to this:
local i = 1
local function Move()
transition.to(player, {time=timeTable[i+1], x=TableX[i+1], y=TableY[i+1]})
i=i+1
end
timer.performWithDelay( timeTable[i], Move, 0 )
It doesn't work although it no error is given.
Thanks in advance for your helpenter code here
May be this would work
local timeTable = {1, 3, 4, 1}
local TableX = {100, 400, 400, 500}
local TableY = {100, 100, 500, 500}
local i = 0
local function onCompleteMove()
i = i + 1
if timeTable[i] then
transition.to(player, {
time=timeTable[i],
x=TableX[i],
y=TableY[i],
onComplete=onCompleteMove
})
end
end
onCompleteMove() -- start moving to first point
Try
Tutorial: Moving objects along a path
Tutorial: Working with curved paths
Method for chain of transition for the same object
local function chainOfTransitions(object, params, ...)
if params then
function params.onComplete()
chainOfTransitions(object, unpack(arg))
end
transition.to(object, params)
end
end
Thanks to all of you!
I accomplished the goal by doing so:
local segmentTransition
local delta = 1
local function onCompleteMove()
i = i + delta
if timeTable[i] then
segmentTransition = transition.to(player2, {
time=timeTable[i],
x=tableX[i+delta],
y=tableY[i+delta],
onComplete=onCompleteMove
})
end
end
onCompleteMove() -- start moving
