I am trying to install and configure Globus Connect Personal for Linux (i have a CentOS 8), following this tutorial. However, when I try to set up Globus connect personal by running ./globusconnectpersonal -start i get this error

does anybody know what this could mean?
I think there needs to be PYTHONHOME and PYTHONPATH. I created a conda environment with just the correct version of python in it. Then I ran ./globusconnectpersonal inside the conda environment.
Using a conda environment also works for the non-GUI form of globus.
I have not tried setting the paths manually.
I ran into the same problem when I was using Python3.8 in a Miniconda environment. When I disabled conda with:
conda deactivate
Then I could run "globusconnectpersonal -start" with my native Python2.7. I don't know if it was because the client needed Python2 or if conda was interfering, but his resolved the problem for me.

I am trying to install openstack Wallaby on Ubuntu 20.04. I already installed Keystone and Glance and they work as expected. But after I installed Placement and tried to verify it using 'placement-status upgrade check' I constantly get the same error.
Error:
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/oslo_upgradecheck/upgradecheck.py", line 196, in run

raise NotInitializedError()
oslo_config.cfg.NotInitializedError: call expression on parser has not been invoked
Is this normal at this stage or am I doing something wrong here?
I already checked the database connections (user and password work and database is made). And I also checked the username, password and url options in keystone_authtoken in placement.conf but I can't find what's wrong.
I also encountered this problem with Wallaby on Ubuntu 20.04. I solved it with installing Placement from PyPI instead of Ubuntu package manager so far. You should consider how implement starting Placement automatically if you install Placement from this instruction.
Install and configure Placement from PyPI
https://docs.openstack.org/placement/wallaby/install/from-pypi.html
I had the same problem so changed to Victoria, same issue. Digging about in the docs though I found the issue. The command that populate the database looks similar for Keystone, Glance and Placement but for placement the command should be 'su -s /bin/sh -c "placement-manage db sync" placement'. Notice that for placement it is 'db sync' not 'db_sync' as it is for the others. I created scripts, well actuall am using ansible and just cut and pasted between them and my guess is you have done the same. Basically as it does not run the database is empty hence the error.

Actual behavior
I am facing an issue when I try to release the assignment:
nbgrader release_assignment ps1 --force --debug
It releases the assignment without errors but to the location (/home/jupyter-tljh-admin/course_id/outbound/ps1) but not to the shared location /srv/nbgrader/exchange:
[ReleaseAssignmentApp | INFO] Overwriting files: /home/jupyter-tljh-admin/course_id ps1
[ReleaseAssignmentApp | INFO] Source: /home/jupyter-tljh-admin/course_id/release/./ps1
[ReleaseAssignmentApp | INFO] Destination: /home/jupyter-tljh-admin/course_id/outbound/ps1
[ReleaseAssignmentApp | INFO] Released as: /home/jupyter-tljh-admin/course_id ps1
The folder /srv/nbgrader/exchange has write permissions.
Please suggest, what could be the issue?
I faced a similar problem. When I opened the Formgrader there was a notification saying that the directory /srv/nbgrader/exchange does not exist or could not be created. I simply created the directory on my own, but not directly. First I created the directory /srv/nbgrader with sudo. Then I cd into that directory and created the subdirectory exchange, also with sudo. I also added a nbgrader_config.py in /etc/jupyter with the following content:
from nbgrader.auth import JupyterHubAuthPlugin
c = get_config()
c.Exchange.path_includes_course = True
c.Authenticator.plugin_class = JupyterHubAuthPlugin
This solved the issue for me.
Create the /srv/nbgrader/exchange directory and add the permissions like this: chmod ugo+rw /srv/nbgrader/exchange
Open the nbgrader_config.py that was created after running nbgrader quickstart <course-id>
Make sure these two lines are present and uncommented:
c.CourseDirectory.course_id = "<course-id>"
c.IncludeHeaderFooter.header = "source/header.ipynb"
Search for the specific line that says: c.CourseDirectory.root = '', uncomment it, and set it to c.CourseDirectory.root = /full/path/to/your/course-id/
Search for the specific line that says: c.Exchange.assignment_dir = '.' and actually set it to c.Exchange.assignment_dir = '/srv/nbgrader/exchange'
Copy this exact nbgrader_config.py into .jupyter or any other directory that apprear in jupyter --paths

I'm trying to get familiar with the robotframework using autoitlibrary to test Windows applications. I found some examples which use the Send command to type text into a notpad window.
That's what I've done so far:
*** Settings ***
Library AutoItLibrary
*** Variables ***
${app} C:/Program Files/Notepad++/notepad++.exe
*** Test Cases ***
Enter text
Run ${app}
Win Wait Active new 1 - Notepad++
Send This is just a test.
So, the Notepad++ window is opened, but then it failed with the No keyword with name 'Send' found. message. I suppose there is no Send command in the AutoItLibrary, but I also cannot find any other command which may do this job.
AutoIt is installed, and so is the wrapper by pip install robotframework-autoitlibrary.
There really exists a Send keyword in AutoIt, but supposedly not in the wrapper for robotframework.
And ideas to fix this?
UPDATE: Windows 10 (64bit in a VirtualBox), Python v3.7.6 (32bit), RF v3.1.2, RF-AutoItLibrary v1.2.4, AutoIt v3.3.14.5
The "Search Keywords" dialog in RIDE provides AutoItLibrary as a Source, but then list only a few commands. So I suppose the library is accessible, but incomplete.
import os, re, subprocess, sys
# Set path to Python directories.
programfiles = os.environ['programfiles']
if not programfiles:
exit('Failed to get programfiles')
python_dirs = [os.path.join(programfiles, 'Python35'),
os.path.join(programfiles, 'Python36'),
os.path.join(programfiles, 'Python37'),
os.path.join(programfiles, 'Python38')]
# Process each python directory.
for python_dir in python_dirs:
print('---')
# Set path to AutoItX3.dll.
autoitx_dll = os.path.join(python_dir, r'Lib\site-packages\AutoItLibrary\lib\AutoItX3.dll')
if not os.path.isfile(autoitx_dll):
print('File not found: "' + autoitx_dll + '"')
continue
# Set path to the makepy module.
makepy = os.path.join(python_dir, r'Lib\site-packages\win32com\client\makepy.py')
if not os.path.isfile(makepy):
print('File not found: "' + makepy + '"')
continue
# Generate cache using make.py.
command = [os.path.join(python_dir, 'python.exe'), makepy, autoitx_dll]
with subprocess.Popen(command, stderr=subprocess.PIPE, cwd=python_dir, universal_newlines=True) as p:
stderr = p.communicate()[1]
print(stderr.rstrip())
parameters = re.findall(r'^Generating to .+\\([A-F0-9\-]+)x(\d+)x(\d+)x(\d+)\.py$', stderr, re.M)
if len(parameters) == 1:
parameters = parameters[0]
print('Insert the next line into AutoItLibrary.__init__.py if not exist.\n'
' win32com.client.gencache.EnsureModule("{{{guid}}}", {major}, {minor}, {lcid})'
.format(guid=parameters[0],
major=parameters[1],
minor=parameters[2],
lcid=parameters[3]))
# Pause so the user can view the subprocess output.
input('Press the return key to continue...')
The generated cache done by win32com\client\makepy.py for AutoItLibrary from the setup.py is saved in the %temp%\gen_py folder. This is done only when setup.py is executed. If the %temp% directory is cleaned later, which removes the cache, then I notice keywords like Send may fail to be recognized by the robotframework.
One solution appears to be regenerating the cache. The code above will generate the cache by use of makepy.py. It may also print a message about inserting win32com.client.gencache.EnsureModule(...) into AutoItLibrary\__init__.py for any of the Python versions as needed. This will ensure the cache is available when AutoItLibrary
is imported.
Change paths in the code to suit your environment.
With further research:
AutoItLibrary currently has AutoItX 3.3.6.1 and latest AutoIt has AutoItX 3.3.14.5. Important to know as one version registered can overwrite the registration of the previous registration.
AutoItLibrary currently registers AutoIt3X.dll without the _x64 suffix on the name on x64 systems. I may reference AutoIt3_x64.dll to define difference between x86 and x64.
Any version of AutoIt3X.dll and AutoIt3_x64.dll uses the same ID codes and the last registered wins (based on bitness as both x86 and x64 registrations can co-exist).
The TypeLib class key registered ID is {F8937E53-D444-4E71-9275-35B64210CC3B} and is where win32com may search.
If AutoIt3X.dll and AutoIt3_x64.dll are registered, unregister any 1 of those 2 will remove the AutoItX3.Control class key. Without this key, AutoIt3X will fail as AutoItLibrary needs this key. To fix, register again e.g. regsvr32.exe AutoIt3X.dll as admin in the working directory of AutoIt3X.dll.
The methods of any same version of AutoItX will match i.e. AutoIt3X.dll and AutoIt3X_x64.dll only changes in bitness, not methods.
Inserting win32com.client.gencache.EnsureModule("{F8937E53-D444-4E71-9275-35B64210CC3B}", 0, 1, 0) into AutoItLibrary\__init__.py should ensure the cache is always available for any AutoItX version. The initial code can be used to generate the cache, though the suggested change in AutoItLibrary\__init__.py makes it obsolete as the cache is generated on import of AutoItLibrary. If the ID was not constant, then the initial code may inform you of the ID to use.
The cache is important as it has generated .py files with methods like e.g.:
def Send(self, strSendText=defaultNamedNotOptArg, nMode=0):
'method Send'
# etc...
which if missing, makes Send and many others, an invalid keyword in AutoItLibrary.
If AutoItX 3.3.14.5 is registered, the - leading methods are removed and the + leading methods are added as compared to AutoItX 3.3.6.1:
-BlockInput
-CDTray
-IniDelete
-IniRead
-IniWrite
-RegDeleteKey
-RegDeleteVal
-RegEnumKey
-RegEnumVal
-RegRead
-RegWrite
-RunAsSet
+RunAs
+RunAsWait
So if any of those methods causes error, then you may want AutoItX 3.3.6.1 registered instead. In the AutoItX history, 3.3.10.0 release is when those method changes happened.
Fix:
Check your python architecture ( is it 32 or 64 bit)
For 32:
Open cmd in "Run as administrator" mode
run the command pip install robotframework-autoitlibrary
Now clone the autoit library source code:
https://github.com/nokia/robotframework-autoitlibrary
in the root directory run the below command: python setup.py install using cmd in admin mode
to navigate to root directory use the command pushd <filepath>' instead ofcd ` if cd doesn't work in cmd opened in admin mode.
For 64:
Open cmd in "Run as administrator" mode
Now clone the autoit library source code:
https://github.com/nokia/robotframework-autoitlibrary
in the root directory run the below command: python setup.py install using cmd in admin mode
to navigate to root directory use the command pushd <filepath>' instead ofcd ` if cd doesn't work in cmd opened in admin mode.
After going through a lot of sites about best terminal for system admins I was trying to install on Cygwin. Unfortunately, I did not find any good site with instruction about how to do it.
Is anyone done this before? Please help me with steps and packages that I need to install.
Also is there any terminals I can try (like Cygwin)?
I don't know since what version, but now you can install terminator just from the Cygwin installer. And runs great
Regards
If you don't want to use cygwinports, you can actually install all of terminator's dependencies from the cygwin installer, except for terminator itself.
In the cygwin installer select and install:
python-dbus
python-gobject
python-gtk2.0
python-vte (under GNOME tab for some reason)
GConf2
Then, pull down the latest terminator tarball from https://launchpad.net/terminator/+download and extract it somewhere. In a administrator terminal just run python setup.py install and as long as you have a running X server just running terminator will work perfectly.
The sources about how to install terminator are a bit obscures. What I did, and may help you, was this: (although I'm still having segmentation faults errors)
Update your Cygwin to the latest
Open a Cygwin terminal and run: (if you have the x86 version use that. The idea of this step is to use Cygwin Ports)
cygstart -- /your/cygwin/path/setup-x86_64.exe -K http://cygwinports.org/ports.gpg
In the section Choose A Download Site:
Add "http://downloads.sourceforge.net/cygwin-ports"
Add " ftp://ftp.cygwinports.org/pub/cygwinports"
Select another mirror close to you
Check that you have a total of three URLs selected
It may show you warning about not loading the .ini configuration but ignore them (Note: I looked for different port URLs but the official ones threw me errors and I could not pass this step, that's why I used alternatives URLs)
First, you need to install the packages for the X Window:
http://x.cygwin.com/docs/ug/setup.html
Basically they are:
xorg-server (required, the Cygwin/X X Server)
xinit (required, scripts for starting the X server: xinit, startx, startwin (and a shortcut on the Start Menu to run it), startxdmcp.bat )
xorg-docs (optional, man pages)
Also search and select the terminator package
It takes quite a while before it finishes.
Go to Start->All Programs->Cygwin-X->X Win Server (windows tool bar)
A xterm window should open. Type:
terminator
You should know have terminator with Cygwin.
Note: After I run terminator I get this error:
/usr/lib/python2.7/site-packages/terminatorlib/terminator.py:87: Warning: Attempt to add property GnomeProgram::sm-connect after class was initialised

Warning: python-keybinder is not installed. This means the hide_window shortcut will be unavailable

I've looking to fix this issue but sadly I couldn't find anything. If you use Cygwin x86 your outcome can be different.
Hope this can help you.
I wanted to run this example script: http://mazamascience.com/WorkingWithData/?p=912 from Windows command line. So I opened the command line and typed Rscript tryCatch.R 1. However, I keep getting the error message Error: R not found. I did set the PATH environment variable as C:\Programme\R\R-3.0.1\bin. If I just type R.exe, it does start R, but it cannot find the packages that are to be loaded at start (e.g. package 'utils' in options<"defaultPackages"> was not found). I guess I have to set another path to the libraries somewhere, but I haven't got any idea where to do this.
UPDATE: After explicitly typing PATH C:\Programme\R\R-3.0.1\bin (rather than just adding this to the value of the environment variable PATH) it seems that R is found. However, a new problem occurs: In normalizePath<path.expand(path), winslash, mustWork>: path[2] = "C:/Programme/R/R-3.0.1/library": Access denied, the same than for the methods library. Then: Calls: .First ... library -> .getRequiredPackages2 -> library -> normalizePath Execution stopped. I'm using Windows 7 and I do have administrator rights.
Rscript is very handy (R CMD BATCH is the old way to ) specially under windows, But generally under I create a batch file to avoid all path's headache.
For example say launcher.bat:
#echo off
C:
PATH C:\Programme\R\R-3.0.1\bin;%path%
cd PATH_TO_YOUR_RSCRIPT
Rscript tryCatch.R 1
pause
And open a console(using cmd) , go where you have stored your launcher.bat and launch it. Or from the R cosnole using shell:
shell('path_to_launcher\launcher.bat')
I've found out that it was a language-specific problem on Windows 7, similar to what is described here: https://stat.ethz.ch/pipermail/r-help/2011-May/276932.html
After changing PATH to C:\Program Files\R\R-3.0.1\bin the script is properly executed from the command prompt.
Thanks to everyone who tried to help!
I ran into this problem under windows 7, apparently, when setting environment variables>user variables the path is not added into the PATH, so the user must add this path in system variables > PATH
at the end just add the path to your .EXE files and voila.
