I suppose I am running the latest version on MIDO.
pip freeze | grep mido
mido==1.2.9
what am doing wrong?
Any help would be greatly appreciated.
I am no expert, but I had a similar problem.
The time attribute in mido is a bit confusing as it can either represents ticks or time deltas. From the documentation (https://mido.readthedocs.io/en/latest/midi_files.html#about-the-time-attribute
):
The time attribute is used in several different ways:
inside a track, it is delta time in ticks. This must be an integer.
in messages yielded from play(), it is delta time in seconds (time elapsed since the last yielded message)
(only important to implementers) inside certain methods it is used for absolute time in ticks or seconds

I have started programming an Arithmetic Strategy Use task in PsychoPy. The idea is to have a total of 80 arithmetic problems, which would essentially end up being 4 conditions; single addition (20 problems), single subtraction (20 problems), double addition (20 problems), double subtraction (20 problems).
What I have done so far:
I created 4 excel sheets; one per condition with 20 arithmetic problems
I inserted a routine called Trial and inserted 4 loops with Single Subtraction, Single Addition, Double Subtraction and Double addition.
I included a strategy report question after each trial
I tried to run the experiment, however, several error messages keep popping up and I am not sure how to troubleshoot them! Please find the error messages below:

I tried to run the experiment and expected it to run.
I'm trying to use sagetex package, but then I found this kind of problem when running the code
the result
Here is the code I tried to run:
\documentclass{article}
\usepackage{sagetex}
\usepackage{graphicx}
\usepackage{fancyvrb}
\begin{document}
Using Sage\TeX, one can use Sage to compute things and put them into
your \LaTeX{} document. For example, there are
$\sage{number_of_partitions(1269)}$ integer partitions of $1269$.
You don't need to compute the number yourself, or even cut and paste
it from somewhere.
Here's some Sage code:
\begin{sageblock}
f(x) = exp(x) * sin(2*x)
\end{sageblock}
The second derivative of $f$ is
\[
\frac{\mathrm{d}^{2}}{\mathrm{d}x^{2}} \sage{f(x)} =
\sage{diff(f, x, 2)(x)}.
\]
Here's a plot of $f$ from $-1$ to $1$:
\sageplot{plot(f, -1, 1)}
\sageplot[scale=.5]{plot3d(sin(pi*(x^2+y^2))/2,(x,-1,1),(y,-1,1))}
we know that 2010 factors to $\sage{factor(2010)}$
\begin{sagesilent}
m=identity_matrix(QQ,3)
m[0]=m[0]+m[1]
m[1]=m[1]-m[2]
m[2]=m[2]-2*m[1]
m[1]=m[1]+3*m[0]
m[0]=2*m[0]
\end{sagesilent}
Compute the rref of $\sage{m}$
\begin{sageblock}
g(x)=taylor(tan(x),x,0,10)
\end{sageblock}
$$\tan(x)=\sage{g(x)}$$
\end{document}
When I try to compile this, I get:
**** Error in Sage code on line 23 of file.tex! Traceback follows.
Traceback (most recent call last):
File "file.sagetex.sage.py", line 39, in <module>
_st_.plot(_sage_const_1 , format='notprovided', _p_=plot3d(sin(pi*(x**_sage_const_2 +y**_sage_const_2 ))/_sage_const_2 ,(x,-_sage_const_1 ,_sage_const_1 ),(y,-_sage_const_1 ,_sage_const_1 )))
NameError: name 'y' is not defined
Once a single error occurs, the rest of the Sage output may be lost, leading to all of the question marks. The problem is this line:
\sageplot[scale=.5]{plot3d(sin(pi*(x^2+y^2))/2,(x,-1,1),(y,-1,1))}
and in particular, you have not defined y. (In SageMath, x is automatically defined to be a variable, but not y.) If you add this before the plot, it should work:
\begin{sagesilent}
var('y')
\end{sagesilent}
Documentation is not helpful to me at all.
First, I tried using set() ,but I don't understand what it means by
set an instance for future calls
I could successfully feed my data using my dataset's structure described below.
So, I am not sure why I need to use set for that as it mentioned.
Here is my feature sequence of type scipy.sparse after I called nonzero() method.
[['66=1', '240=1', '286=1', '347=10', '348=1'],...]
where ... imply, same structure as previous elements
Second problem I encountered is Tagger.probability() and Tagger.marginal().
For Tagger.probability, I used the same input as Tagget.tag(), and I get this follwoing error.
and if my input is just a list instead of list of list. I get the following error.

Any clue on how to use these 3 methods?? Please give me shorts example of use cases of these 3 methods.
I feel like there must be some example of these 3 methods, but I couldn't find one. Am I looking at the right place. This is the website I am reading documentation from
Additional info: I am using CliNER. in case any of you are familiar with it.
https://python-crfsuite.readthedocs.io/en/latest/pycrfsuite.html
I know this questions is over a year old, but I just had to figure out the same thing as well -- I am also leveraging some of the CliNER framework. For the CliNER specific solution, I forked the repo and rewrote the predict method in the ./code/machine_learning/crf.py file
To obtain the marginal probability, you need to add the following line to the for loop that iterates over the pycrf_instances after yseq is created (see line 196 here)
y_probs = [tagger.marginal(y, ii) for ii, y in enumerate(yseq)]
And then you can return that list of marginal probabilities from the predict method -- you will in turn be required to rewrite additional functions in the to accommodate this change.
The documentation says that the RTC clock can be initialized with the RTC.init call.
https://docs.micropython.org/en/latest/esp8266/library/machine.RTC.html
But it does not work that way:
>>>import machine
>>>rtc = machine.RTC()
>>>rtc.init((2018,4,10,17,30))
Traceback (most recent call last):
File "<stdin>", line 1 in <module>:
AttributeError: 'RTC' object has no attribute 'init'
So the documentation contradicts reality. The firmware version is v1.9.3 - downloaded the latest just a few days ago.
Most interestingly, dir(rtc) gives ['datetime','memory','alarm','alarm_left','irq','ALARM0']. It is missing several other methods: now, deinit, cancel
So where is the RTC init method, and how could it disappear?
UPDATE: I have figured out that the documentation is wrong, I need to use RTC.datetime instead of RTC.init. But it is still wrong:
>>>from machine import RTC
>>>rtc=RTC()
>>>rtc.datetime((2000,1,1,23,59,59,0,0))
>>>rtc.datetime()
(2000, 1, 3, 0, 11, 59, 3, 705)
In other words: 2000-01-01T23:59:59 suddenly became 2000-01-03T00:11:59. How?
I also could not find anything useful on the tzinfo parameter of the RTC.datetime method. It should be a number, that is clear. But what does it mean?
I have also tried midnight:
>>>rtc.datetime((2000,1,1,0,0,0,0,0))
>>>rtc.datetime()
(2000,1,1,5,0,0,1,155)
So at tzinfo=0, midnight becomes 05:00:00. I first thought that it means UTC+5 but it does not:
>>>rtc.datetime((2000,1,1,10,0,0,0,0))
>>>rtc.datetime()
(2000,1,1,5,0,0,1,155)
And finally:
>>>rtc.datetime((2000,1,1,5,0,0,0,0))
>>>rtc.datetime()
(2000,1,1,5,0,0,1,545)
This is insane! It looks like the hour part is totally ignored.
Wow this is unbelievable! After looking in the source code, it turns out that the fourth parameter is "day of the week", beginning with Monday. So the documentation is totally messed up!
tzinfo parameter does not exist.
The actual parameters in the tuple are:
(year,month,day,day of the week(0-6;Mon-Sun),hour(24 hour format),minute,second,microsecond)
It also seems that when you set the date and time, you can always set day of the week to zero, it will be automatically corrected from the year+month+day.
So for April 10th,2018 at 6:31 P.M. with 15 seconds and 0 microseconds:
>>>rtc.datetime((2018,4,10,0,18,31,15,0))
>>>rtc.datetime()
(2018, 4, 10, 1, 18, 31, 16, 808)
Where the fourth number=1 means it is the SECOND day of the week, Tuesday.
From the picture above in matchDataListener function in line 225, the question is what is the meaning of matchDataEvent.data.data. I have already explored to the reference in http://docs.coronalabs.com/api/type/GameNetwork/match.html but there is no any explanation.
I also don't understand the meaning of
for i = 1, #matchDataEvent.data.participants, 1
in line 244
Could anyone explain them to me?
matchDataEvent.data.data refers to the string inside matchDataEvent.data table/array. I've no idea about what it generally contains though. The line #225 in particular; checks if this string exists and in not empty.
In #matchDataEvent.data.participants, the # is the __len method which returns the length of the table/array matchDataEvent.data.participants. Total number of participants are returned (a number). This number is used as the max value in the for loop.
