it is my first time with saleae.
I’ve installed it on my windows machine and launch a notebook. My problem
is that I can’t create an Saleae object. Here is my code
import saleae
from saleae import Saleae
s = Saleae()
I’m having this error message:
INFO:saleae.saleae:Could not connect to Logic software, attempting to launch it now
Output exceeds the size limit. Open the full output data in a text editor
ConnectionRefusedError Traceback (most recent call last) File ....\lib\site-packages\saleae\saleae.py:211, in Saleae.init(self, host, port, quiet, args) 210 self._s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) → 211 self._s.connect((host, port)) 212 except ConnectionRefusedError: ConnectionRefusedError: [WinError 10061] Aucune connexion n’a pu être établie car l’ordinateur cible l’a expressément refusée
how can I solve the issue ?
I found the solution by reverting back to Logic 1.2.40.

since several days, i can not connect to google drive in google colaboratory.
here is the code, that before always worked:
from google.colab import drive
drive.mount('/content/gdrive/')
I tried the following, after reading several blogs for a solution:
-> I only have two items in my first folder of google drive
-> My trash folder is empty
-> I reset all the sessions
-> I create new file for testing just the piece of code above.
-> I restarted my computer and my browser Chrome
-> I tried "drive.mount('/content/gdrive')" , drive.mount('/content/gdrive/'), drive.mount('/content/'), drive.mount('/content'), drive.mount('/content/gdrive/My Drive')
Any idea?
Thanks a lot!

Workaround is to copy the oauth code using a mouse-drag instead of using the "copy" button.
It looks like someone suggested manually copy-pasting the authentication code generated instead of pressing the copy button and then pasting. This worked for me :)
Hi i copied the authentication code on to notepad and then pasted it from there onto the colab. It worked.
Problem Statement: Extract data stored in the .sdf file to python.
System config: Win 10 Pro 64-bit, python 3.5.2-64 bit, adodbapi library, SQL CE 3.5
I am fairly new to programming and I have picked up Python as my first language to learn. Currently, I have hit a wall in process of connecting a SQL CE 3.5 .sdf file.
I have used the adodbapi library. I have searched the web extensively over the past week to find a solution to this problem and to make sure that my connection string is correct. I have tried multiple options/solutions provided on stack overflow and https://www.connectionstrings.com/microsoft-sqlserver-ce-oledb-3-5/.
Code:
import adodbapi
cons_str = "Provider=Microsoft.SQLSERVER.MOBILE.OLEDB.3.5;" \
"Data Source=D:\Work\Programming\Python\SQL_DataTransfer\LF.sdf;"\
"Persist Security Info=False;" \
"SSCE:Max Database Size=4091"
connection = adodbapi.connect(cons_str)
print(connection)
Error Message:

At this point any help is much appreciated.
Thank you,
Sincerely,
JD.
Looks like you have a typo:
Provoider => Provider
adodbapi version = '2.6.0.6' depends on pypiwin32 to be installed in your Python environment.
For adodbapi.py, from line 51:
if api.onIronPython:
from System import Activator, Type, DBNull, DateTime, Array, Byte
from System import Decimal as SystemDecimal
from clr import Reference
def Dispatch(dispatch):
type = Type.GetTypeFromProgID(dispatch)
return Activator.CreateInstance(type)
def getIndexedValue(obj,index):
return obj.Item[index]
else: # try pywin32
try:
import win32com.client
import pythoncom
import pywintypes
onWin32 = True
def Dispatch(dispatch):
return win32com.client.Dispatch(dispatch)
except ImportError:
import warnings
warnings.warn("pywin32 package (or IronPython) required for adodbapi.",ImportWarning)
def getIndexedValue(obj,index):
return obj(index)
In my situation, I traced the fact that the Dispatch function was not defined because an ImportError exception is generated at line 62, (import win32com.client) caught in the except block but for some reason the warning message was not displayed in my console.
Try:
pip install pypiwin32
and the ImportError exception described above should not be raised anymore.

I'm not sure what this error means
I know it is a late answer but maybe somebody is going to profit from it:
you need to declare the context.browser (in a before_all/before_scenario/before_feature hook definition or just test method definition) before you use it, e.g.:
context.browser = webdriver.Chrome()
Please note that the hooks must be defined in a separate environment.py module
In my case the browser wasn't installed. That can be a case too. Also ensure path to geckodriver is exposed if you are working with Firefox.

Anyone knows how to resolve?
If you get this error, a firewall might be blocking you from downloading a dependency. Here is some information and a work around:
Please see the SFrame source code for get_dependencies to see how GraphLab uses this package: https://github.com/turicode/SFrame/blob/master/oss_src/unity/python/sframe/dependencies.py
The xz utility is only used to extract runtime dependencies from the other file downloaded there (from repo.msys2.org): http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-gcc-libs-5.1.0-1-any.pkg.tar.xz. Two DLLs from that file need to be extracted into the "cython" directory inside the GraphLab Create install path (typically something like lib/site-packages/python2.7/graphlab within a virtualenv or conda env). Once extracted the dependency issue should be resolved.
In graphlab folder make the folder writable.Initially it is only readable.Go to properties of folder undo the only read option.Hope it solve your problem.
I'm using python 2.7.3 on a Windows 7 64-bit machine currently (also developing in Linux 32 bit, Ubuntu 12.04) and am having odd difficulties getting python to communicate with the command prompt/terminal successfully. My code looks like this:
import subprocess, logging, platform, ctypes
class someClass (object):
def runTerminalCommand:
try:
terminalOrCmdLineCommand = self.toString()
process = subprocess.Popen(terminalOrCmdLineCommand, shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
output = process.stdout.readlines()
if len(output) < 1:
logging.exception("{} error : {}".format(self.cmd,process.stderr.readlines()))
raise ConfigError("cmd issue : {}".format(self.cmd))
return output
except ValueError as err:
raise err
except Exception as e:
logging.exception("Unexpected error : " + e.message)
raise ConfigError("unexpected error")
Now, I know that the self.toString() returned value will process correctly if I enter it manually, so I'm limiting this to an issue with how I'm sending it to the command line via the subprocess. I've read the documentation, and found that the subprocess.check_call() doesn't return anything if it encounters an error, so I'm using .Popen()
The exception I get is,
[date & time] ERROR: Unexpected error :
Traceback (most recent call last):
File "C:\[...]"
raise ConfigError("cmd issue : {}".format(self.cmd))
"ConfigError: cmd issue : [the list self.cmd printed out]"
What I am TRYING to do, is run a command, and read the input back. But I seem to be unable to automate the call I want to run. :(
Any thoughts? (please let me know if there are any needed details I left out)
Much appreciated, in advance.
The docs say:
Use communicate() rather than .stdin.write, .stdout.read or
.stderr.read to avoid deadlocks due to any of the other OS pipe
buffers filling up and blocking the child process.
You could use .communicate() as follows:
p = Popen(cmd, stdout=PIPE, stderr=PIPE)
stdout_data, stderr_data = p.communicate()
if p.returncode != 0:
raise RuntimeError("%r failed, status code %s stdout %r stderr %r" % (
cmd, p.returncode, stdout_data, stderr_data))
output_lines = stdout_data.splitlines() # you could also use `keepends=True`
See other methods to get subprocess output in Python.
