QUESTION
I have written a C++ file which contains a function which uses std::logf()
. It contains this line
ANSWER
Answered 2021-May-31 at 09:23Is this a gcc problem?
Yes. And it is reported. To be fair, it was somewhat unclear whether std::logf
was required to exist due to an editorial mistake which caused a contradiction in the standard that was fixed in C++17.
You can work around it by using std::log(float)
instead. Another workaround is to use ::logf
, although that isn't necessary since you can use std::log(float)
.
QUESTION
Problem: I have a struct which contains a map and two slices. When I pass the pointer value, no matter what I do, these collections within the struct are always nil (i.e. cannot append anything to the map or slices).
Details: I cannot figure out why this is happening. I made a seemingly unrelated change (which I can't remember) and now nothing will append to the Map in the struct. I am passing the Map pointer to subsequent functions, but it keeps throwing an error "panic: assignment to entry in nil map".
I pass the pointers for the LinkResource and the LinkReport type values, but it always says the map is nil. I even forcefully Zeroed the LinkReport struct values with make(...) as a debugging test, but when the value is passed to subsequent functions it still claims the Map and Slices are nil; how is this possible and how do I correct it?

QUESTION
I am supplying different minibatches to optimize a GPflow model (SVGP). If I decorate the optimization_step
with tf.function
I get the following error:
NotImplementedError: Cannot convert a symbolic Tensor (concat:0) to a numpy array. This error may indicate that you're trying to pass a Tensor to a NumPy call, which is not supported
In order for the optimizer to run I had to remove the tf.function
decorator, losing the speed-up advantages. What do I need to change so that I can keep using the tf.function
decorator?
The xAndY
input shapes and types are all numpy
arrays.
ANSWER
Answered 2021-Feb-14 at 18:01GPflow's gpflow.optimizers.Scipy()
is a wrapper around Scipy's minimize(), and as it calls into non-TensorFlow operations, you cannot wrap it in tf.function
. Moreover, the optimizers implemented in Scipy's minimize are second-order methods that assume that your gradients are not stochastic, and aren't compatible with minibatching.
If you want to do full-batch optimization with Scipy: The minimize()
method of gpflow.optimizers.Scipy()
, by default, does wrap the objective and gradient computation inside tf.function
(see its compile
argument with default True
). It also does the full optimization, so you only have to call the minimize()
method once (by default it runs until convergence or failure to continue optimization; you can supply a maximum number of iterations using the options=dict(maxiter=1000)
argument).
If you want to use mini-batching: simply use one of the TensorFlow optimizers, such as tf.optimizers.Adam()
, and then your code should run fine including the @tf.function
decorator on your optimization_step()
function (and in that case you do need to call it in a loop as in your example).

i have the following form with 2 inputs (or more). i need to change the label style when input:focus
and input:valid
and to do so i need label

how can i reorder label and input with pure javascript?!
p.s. i can't change html manually :)
and please don't mind the css below, it includes additional styles i use for other forms on the page i work on

QUESTION
I'm using aws-go-sdk to create and manage spot instances. Every request I send in order to create a new Spot Instance Request is performed with RequestSpotInstances. I'm trying to get the Instance ID of the instance that was created for my last request, I saw that in the response object RequestSpotInstancesOutput there is a parameter for each instance that was created, but it does not include the instance id, in fact, the InstanceID is not being filled in the RequestSpotInstanceOutput, (returned from RequestSpotInstances call), I tried to use CreateTags in order to create a tag for each instance with the request id, but it didn't work. seen here: TagSpecifications with requestSpotInstances UnexpectedParameter with aws-sdk
...ANSWER
Answered 2021-Jan-24 at 23:02I think that it can take some time for a Spot Instance request to be fulfilled.
I would recommend you call describe_spot_instance_requests()
until the Status
of all instances is fulfilled
(wait a little bit between each call).
I can't see a field that indicates that the whole request has been fulfilled, so you might need to compare the number of instances returned against the quantity that you requested.
QUESTION
I need to print all form requests to log, for later debugging. I need to have something like this, where formInput
are different kind of structs. (All defined in my code.)
ANSWER
Answered 2020-Dec-10 at 08:53There is no completely general solution to this. There are only specific solutions with different trade-offs.
Perhaps the most general solution would be to write a function that inspects each form type with reflection, and omits any sensitive fields in the output.

QUESTION
I'm testing a c code for linux with large arrays to measure thread performance, the application scales very well when threads are increased until max cores (8 for Intel 4770), but this is only for the pure math part of my code.
If I add the printf part for resulted arrays then the times becomes too large, from few seconds to several minutes even if redirected to a file, when printf those arrays should add just a few seconds.
The code:
(gcc 7.5.0-Ubuntu 18.04)
without printf loop:
gcc -O3 -m64 exp_multi.c -pthread -lm
with printf loop:
gcc -DPRINT_ARRAY -O3 -m64 exp_multi.c -pthread -lm
...ANSWER
Answered 2020-Oct-15 at 21:27I don't think this has much to with pthread
because your code only appears to call printf
after the threads are joined. Instead, the poor performance is likely due to cache misses by needing to read from the xv
and yv
arrays in every iteration of the print loop.
QUESTION
I have a simply shader creation pipeline. Nothing special. The shader source reads in properly from what I can tell. Originally, I had the shader code in files with a suffix of '.glsl' just because I wanted to, but they are now plain '.txt' files.
After reading in the shader code, I compile the shader and link the shader as well as check the compile status and info log for errors. The actual shader code below doesn't look to me like it has an error considering it't now basically a carbon copy of a simple tutorial you can find online which I'll link if you need it.
I do get an error though, which is "0(1) : error C0104: Unknown pre-processor directive #version330". This is the same for both the vertex and the fragment shaders, which have an almost identical creation process.
My driver version is [4.6.0 NVIDIA 445.87] as well, so I should be able to use #version 330. I did also have them both set to '#version 330 core', but I was getting the same error.
This is my program and shader creation process.
...ANSWER
Answered 2020-Sep-07 at 13:23Your while (file >> line)
loop reads on a word-by-word basis. Appending each word to a string effectively strips all whitespace from your shader.
Instead, do this to read the file as-is into a std::string
