Pyinstaller with APScheduler - TypeError with IntervalTrigger

I had the same problem as here (see link below), brielfy: unable to create .exe of a python script that uses APScheduler
Pyinstaller 3.3.1 & 3.4.0-dev build with apscheduler
So I did as suggested:
from apscheduler.triggers import interval
scheduler.add_job(Run, 'interval', interval.IntervalTrigger(minutes = time_int),
args = (input_file, output_dir, time_int),
id = theID, replace_existing=True)
And indeed importing interval.IntervalTrigger and passing it as an argument to add_job solved this particular error.
However, now I am encountring:
TypeError: add_job() got multiple values for argument 'args'
I tested it and I can ascertain it is occurring because of the way trigger is called now. I also tried defining trigger = interval.IntervalTrigger(minutes = time_int) separately and then just passing trigger, and the same happens.
If I ignore the error with try/except, I see that it does not add the job to the sql database at all (I am using SQLAlchemy as a jobstore). Initially I thought it is because I am adding several jobs in a for loop, but it happens with a single job add as well.
Anyone know of some other workaround if the initial problem, or any idea why this error might occur? I can't find anything online either :(

Things always work better in the morning.
For anyone else who encounters this: you don't need both 'interval' and interval.IntervalTrigger() as arguments, the code should be, this is where the error comes from.
scheduler.add_job(Run, interval.IntervalTrigger(minutes = time_int),
args = (input_file, output_dir, time_int),
id = theID, replace_existing=True)

Getting a selection in 3ds Max into a list in Python

I am writing in Python, sometimes calling certain aspects of maxscript and I have gotten most of the basics to work. However, I still don't understand FPValues. I don't even understand while looking through the examples and the max help site how to get anything meaningful out of them. For example:
import MaxPlus as MP
import pymxs
MPEval = MP.Core.EvalMAXScript
objectList = []
def addBtnCheck():
select = MPEval('''GetCurrentSelection()''')
objectList.append(select)
print(objectList)
MPEval('''
try (destroyDialog unnamedRollout) catch()
rollout unnamedRollout "Centered" width:262 height:350
(
button 'addBtn' "Add Selection to List" pos:[16,24] width:88 height:38
align:#left
on 'addBtn' pressed do
(
python.Execute "addBtnCheck()"
)
)
''')
MP.Core.EvalMAXScript('''createDialog unnamedRollout''')
(I hope I got the indentation right, pretty new at this)
In the above code I successfully spawned my rollout, and used a button press to call a python function and then I try to put the selection of a group of objects in a variable that I can control through python.
The objectList print gives me this:
[<MaxPlus.FPValue; proxy of <Swig Object of type 'Autodesk::Max::FPValue *' at 0x00000000846E5F00> >]
When used on a selection of two objects. While I would like the object names, their positions, etc!
If anybody can point me in the right direction, or explain FPValues and how to use them like I am an actual five year old, I would be eternally grateful!

Where to start, to me the main issue seems to be the way you're approaching it:
why use MaxPlus at all, that's an low-level SDK wrapper as unpythonic (and incomplete) as it gets
why call maxscript from python for things that can be done in python (getCurrentSelection)
why use maxscript to create UI, you're in python, use pySide
if you can do it in maxscript, why would you do it in python in the first place? Aside from faster math ops, most of the scene operations will be orders of magnitude slower in python. And if you want, you can import and use python modules in maxscript, too.

import MaxPlus as MP
import pymxs
mySel = mp.SelectionManager.Nodes
objectList = []
for each in mySel:
x = each.Name
objectList.append(x)
print objectList

The easiest way I know is with the
my_selection = rt.selection
command...
However, I've found it works a little better for me to throw it into a list() function as well so I can get it as a Python list instead of a MAXscript array. This isn't required but some things get weird when using the default return from rt.selection.
my_selection = list(rt.selection)
Once you have the objects in a list you can just access its attributes by looking up what its called for MAXscript.
for obj in my_selection:
print(obj.name)

"Re-declared Defined Without Usage" One Script but Not The Other?

This sounds like it should be blindingly obvious but there's something quirky going on.
So I have two scripts. Largely the same but a few variances here and there. They both run big loops and they both use global variables. Yes, I know this is bad. Tidying it up is on my to do list but I'm on a time constraint at the moment.
One script works fine. As expected.
The other works fine... for the most part. Then it bugs out once it iterates through the loop again. It's very strange because the code has very little differences but I did pick up on something which I can't explain.
The variable I use to track my position in the loop is set like this in script 1 (which works flawlessly):
global CurrentMatchScan
while True:
print "=Starting Loop="
Loopcounter = 0
CurrentMatchScan = -1
LoadMatch()
The second script has:
global CurrentMatchScan
while True:
print "=Starting Loop="
Loopcounter = 0
CurrentMatchScan = -1
LoadMatch()
However in the second script PyCharm highlights the = -1 part as
Redclared'CurrentMatchScan' defined above without usage
So the obvious assumption is something further up in the code is using it. I do call a function later on which is placed up there...
def LoadMatch():
nextbox1 = LinkList[CurrentMatchScan + 1]
nextbox2 = LinkList[CurrentMatchScan + 2]
But this is only called once CurrentMatchScan is set... and the first script has the exact same code.
Is my IDE just not noticing it on the other script or something? There's a pretty big issue with the looping on the second one and this is the only difference I can see between the two.
I know this doesn't look like a lot to go on but there's not much else to it that I can see. It's barely actually referenced.
I'd really appreciate anyone who can point out how much of an idiot I'm being and missing something really simple.
/edit:
Based on the fact that it does use CurrentMatchScan and calls LoadMatch() for the first iterations properly I'm starting to doubt this is anything but PyCharm trying to warn me I'm potentially doing something silly.
I think if this was the issue it wouldn't work at all so the warning might be a bit of a red herring when it comes to the issue I'm actually facing.

Clear and exit_fullscreen seem not to work

I've started to play around with blessings - so far I'm liking it a lot since it does make things a lot easier.
However I tried to clear the screen without success... enter_fullscreen seems to work tho since that "clears" it - but exit_fullscreen doesn't bring me back to the original view.
term = blessings.Terminal()
term.enter_fullscreen
with term.location():
print(term.move(0,(term.width/2)-7) + term.bold_green("Test Test Test"))
print(term.move(5,(term.width/2)-7) + term.bold_red("Test Test Test"))
time.sleep(5)
term.clear
term.exit_fullscreen
This works except for clear and exit_fullscreen it seems. There is no error message or anything, it just doesn't seem to do anything.
Does anyone know how it works?
Edit: Neither
term.clear
nor
term.clear()
seem to work...
edit2:
I can pretty much do this and the result is the same as above. It does the coloring and placement but not clearing or anything else.
term = blessings.Terminal()
with term.location():
print(term.move(0,(term.width/2)-7) + term.bold_green("Test Test Test"))
print(term.move(5,(term.width/2)-7) + term.bold_red("Test Test Test"))

Just as with all the other capabilities exposed by Blessings, you have to print them for them to have any effect. What's happening under the covers is that your terminal emulator is "listening" for certain sequences, and then it responds by taking actions such as switching in or out of fullscreen mode. So, in your case, saying print term.enter_fullscreen should do the trick. Let me know if you have any more problems!

As I read through your issue (facing the same one myself) I realized that I had forgotten that all the term.some_formatting() calls returned a value that you then had to print. The clear function merely returns the appropriate escape sequences.
If you add:
print(term.clear())
when you want it cleared it should work.
Additionally, I had issues with ex_fullscreen, so I used the wrapper style call of fullscreen:
with term.fullscreen():
a_function_or_some_code()
That should return you to your previous state upon exiting the code block.

How would you adblock using Python?

I'm slowly building a web browser in PyQt4 and like the speed i'm getting out of it. However, I want to combine easylist.txt with it. I believe adblock uses this to block http requests by the browser.
How would you go about it using python/PyQt4?
[edit1] Ok. I think i've setup Privoxy. I haven't setup any additional filters and it seems to work. The PyQt4 i've tried to use looks like this
self.proxyIP = "127.0.0.1"
self.proxyPORT= 8118
proxy = QNetworkProxy()
proxy.setType(QNetworkProxy.HttpProxy)
proxy.setHostName(self.proxyIP)
proxy.setPort(self.proxyPORT)
QNetworkProxy.setApplicationProxy(proxy)
However, this does absolutely nothing and I cannot make sense of the docs and can not find any examples.
[edit2] I've just noticed that i'f I change self.proxyIP to my actual local IP rather than 127.0.0.1 the page doesn't load. So something is happening.

I know this is an old question, but I thought I'd try giving an answer for anyone who happens to stumble upon it. You could create a subclass of QNetworkAccessManager and combine it with https://github.com/atereshkin/abpy. Something kind of like this:
from PyQt4.QtNetwork import QNetworkAccessManager
from abpy import Filter
adblockFilter = Filter(file("easylist.txt"))
class MyNetworkAccessManager(QNetworkAccessManager):
def createRequest(self, op, request, device=None):
url = request.url().toString()
doFilter = adblockFilter.match(url)
if doFilter:
return QNetworkAccessManager.createRequest(self, self.GetOperation, QNetworkRequest(QUrl()))
else:
QNetworkAccessManager.createRequest(self, op, request, device)
myNetworkAccessManager = MyNetworkAccessManager()
After that, set the following on all your QWebView instances, or make a subclass of QWebView:
QWebView.page().setNetworkAccessManager(myNetworkAccessManager)
Hope this helps!

Is this question about web filtering?
Then try use some of external web-proxy, for sample Privoxy (http://en.wikipedia.org/wiki/Privoxy).

The easylist.txt file is simply plain text, as demonstrated here: http://adblockplus.mozdev.org/easylist/easylist.txt
lines beginning with [ and also ! appear to be comments, so it is simply a case of sorting through the file, and searching for the correct things in the url/request depending upon the starting character of the line in the easylist.txt file.

Privoxy is solid. If you want it to be completely API based though, check out the BrightCloud web filtering API as well.
