QUESTION
I am following the Tensorflow guide on Functions here, and based on my understanding, TF will trace and create one graph for each call to a function with a distinct input signature (i.e. data type, and shape of input). However, the following example confuses me. Shouldn't TF perform the tracing and construct the graph only once since both inputs are integers and have the exact same shape? Why is that the tracing happening both times when the function is called?
...ANSWER
Answered 2021-Dec-21 at 19:54The numbers 2 and 3 are treated as different integer values and that is why you are seeing "Tracing!" twice. The behavior you are referring to: "TF will trace and create one graph for each call to a function with a distinct input signature (i.e. data type, and shape of input)" applies to tensors and not simple numbers. You can verify that by converting both numbers to tensor constants:
QUESTION
I'm fairly new at coding pinescript and am trying to code a custom alert where if price crosses under a fibonacci golden level (0.382, 0.50, or 0.618) and bar state is confirmed, it will return true and trigger an alert.
FYI, I'm analyzing and building upon TradingView's built-in Auto Fib Retracement Indicator script to use as an alert. I'm having difficulty trying to retrieve the fibonacci values to compare. I notice when using auto fib retracement tool, it plots the fibonacci level (in decimal format) along with the price and I was wondering how do I retrieve it to compare where price has hit the levels within it if that's the correct way to go about it?
Code Snippet (my added alert code from the bult-in indicator):
...ANSWER
Answered 2021-Nov-15 at 17:05value_0_382 holds the fibonacci level actually (0.382). What you are looking for is calculated within the processLevel() function and named r.
You can easily check that modifying the code such that processLevel() returns the value of r and plot the returned value.
QUESTION
I'm trying to port a working MATLAB code in Python. I am trying to create the var array with size (rows, cols). If an exception is raised, I catch it and try again to create the var array with size (rows, cols-1). If cols gets to zero, then I cannot do anything else, so I rethrow the previously caught exception.
The code snippet is as follows:
...ANSWER
Answered 2021-Nov-04 at 16:20The corresponding syntax is just raise: raise e (note: it’s not a function) adds a stacktrace entry for itself. (In Python 2, it replaced the previous stacktrace like MATLAB’s ordinary throw, but Python 3 extends it.)
QUESTION
I need to train a GPR model in multiple batches per epoch using a custom loss function. I would like to do this using GPflow and I would like to compile my training using tf.function to increase the efficiency. However, gpflow.GPR must be re-instantiated each time you supply new data, so tf.function will have to re-trace each time. This makes the code slower rather than faster.
This is the initial setup:
...ANSWER
Answered 2021-Oct-27 at 15:11You don't have to re-instantiate GPR each time. You can construct tf.Variable holders with unconstrained shape and then .assign to them:
QUESTION
According to https://stackoverflow.com/a/53458191/1635488 if we publish aab files, the mapping files will automatically be taken from there. What happens if we upload it anyway? Will it override the one from the aab file? The place where I can upload it is here: "ReTrace mapping file"
...ANSWER
Answered 2021-Oct-26 at 07:42I did an experiment and can confirm that if we upload only aab file, mapping file will be taken from the aab. If we also upload a separate mapping file, it will override the one in the aab.
QUESTION
I'm trying to replace the following lines of code with an array and a loop. The reason is because they are almost identical.
...ANSWER
Answered 2021-Sep-22 at 13:20The Pine functions is not "pure" (stateless) functions but it is functional objects with STATE. The var variables in function scopes is an one part of this STATE. Each function call is separate functional object. When you made the "repeated lines" you declare several functional objects of f_drawLabel with each own var label _lbl and var line _ln instances. When you try to call f_drawLine in the loop, one functional object is created with single var line _ln instance.
You needs to make the array of lines var line[] _lns = array.new... and make additional argument:

QUESTION
Afternoon all,
Is there a way to create line.new once a 30 minute candle has closed for every $50's of that candle.
Then when price passes back through those lines are then deleted and not recreated?
I am trying to get it to highlight single prints, where price within a 24 hour period has not been retraced after a 30 min candle.
I think the non-broken element within this question might work. Extending plot function

Given a git repository that has a .gitignore pointing towards bar/foo/file adding that file prints it fails adding them – it should require forcing through -f – while at the same time actually adding them.
More precisely the following command and its outputs are confusing:

Answered 2021-Jun-03 at 17:18The file was already tracked. I agree the hint is wrong, you've found a corner case the newbie-helper logic didn't anticipate. I'd recommend git config advice.addignoredfile false.

Install retrace
You can use retrace like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
