I get a syntax error in the following command of LogisticRegression. Can someone please advise where I might be going wrong here?
from sklearn import linear_model
lm = linear_model.LogisticRegression (C = 1e3)
lm.fit (m[:lags].T, np.sign(m[lags])
LogisticRegression (penalty ='l2', tol = .0001, C = 1000000.0, class_weight = None, dual = False, fit_intercept = True,
intercept_scaling = 1, random_state = None, solver ='liblinear', max_iter = 100, multi_class ='ovr',verbose = 0,
warm_start = False, n_jobs = 1)
Error:

SyntaxError: invalid syntax
you have missing closing parenthesis here:
lm.fit (m[:lags].T, np.sign(m[lags]) <--
change to
lm.fit (m[:lags].T, np.sign(m[lags]))

I am trying to get proper synchronization working in trying to get a compute shader writing to an image. However, when I enable validation layers I get the following errors:

I have a problem with read a file JSON, that file contains an array objects like this:

show me this error:

please help me, thanks for your attention.
Try to use with when opening files, it's a better approach, see here more info.
This code is working:
import sys

try:

ls_plano: dict = json.load(read_content)
except (FileNotFoundError, PermissionError, OSError, ValueError) as e:
print(f"Error opening the file: {e}")
sys.exit()

How i get resolve the issue
construct an small app using shiny, after i code a loop it keeps giving me error

it seems that something wrong with the for() sentence
I'm trying to create a simple addon for world of warcraft which records my kills.
I've already got'n quite far except there is a problem with the writing of a lua array.
The code I have so far
local CharacterDefaults = {
kills = {},
totalkills = 0
}
local killDefaults = {
DBtimeofday = 0,
DBplayer = 0,
DBenemyname = 0,
DBenemyid = 0,
DBzone = 0,
DBkilltype = 0
}
The next piece is inside a event which checks for overkill
if not KillCount then
KillCount = CharacterDefaults
end
if not KillCount.totalkills then
KillCount.totalkills = 0
end
KillCount.enemy[KillCount.totalkills] = destName
KillCount.kills[KillCount.totalkills] = killDefaults
KillCount.kills[KillCount.totalkills].DBtimeofday = stamp
KillCount.kills[KillCount.totalkills].DBzone = zone
KillCount.kills[KillCount.totalkills].DBkilltype = killtype
KillCount.kills[KillCount.totalkills].DBenemyid = unitId
KillCount.kills[KillCount.totalkills].DBenemyname = destName
KillCount.kills[KillCount.totalkills].DBplayer = playerName
KillCount.totalkills = KillCount.totalkills + 1
Ofcourse there's more code but this is the only important code (as far as I know).
If I look at this I would expect that for every new kill a new array part is made and the values are entered. However, for each kill I make in world of warcraft, every single item already in it will get the results of the last kill.
The lua variables saved file:
KillCount = {
["kills"] = {
{
["DBplayer"] = "MyName",
["DBzone"] = "Blackrock Depths",
["DBkilltype"] = 0,
["DBenemyname"] = "Grim Patron",
["DBenemyid"] = 9545,
["DBtimeofday"] = "11-09-22 10:45:23",
}, -- [1]
{
["DBplayer"] = "MyName",
["DBzone"] = "Blackrock Depths",
["DBkilltype"] = 0,
["DBenemyname"] = "Grim Patron",
["DBenemyid"] = 9545,
["DBtimeofday"] = "11-09-22 10:45:23",
}, -- [2]
[0] = {
["DBplayer"] = "MyName",
["DBzone"] = "Blackrock Depths",
["DBkilltype"] = 0,
["DBenemyname"] = "Grim Patron",
["DBenemyid"] = 9545,
["DBtimeofday"] = "11-09-22 10:45:23",
},
},
["totalkills"] = 3,
}
as you can see the [0] is the only one to be properly writen. Am I doing something wrong?
The problem is here:
KillCount.kills[KillCount.totalkills] = killDefaults
Everytime you kill, you're pointing KillCount.kills[KillCount.totalkills] to killDefaults then modifying killDefaults. The problem is, you are using the same killDefaults every time. So when you udpate the values of killDefaults later, it affects every reference to killDefaults that you have already created.
Try something like:
function GetDefaultKills()
return {
DBtimeofday = 0,
DBplayer = 0,
DBenemyname = 0,
DBenemyid = 0,
DBzone = 0,
DBkilltype = 0
};
end
KillCount.kills[KillCount.totalkills] = GetDefaultKills()
