paraview-glance-py's Introduction

paraview-glance-py

Build Status

This is built off of ParaView Glance.

Installation

Download the stand-alone executable:

Operating System Executable
Linux paraview-glance-py.linux.x86_64
macOS paraview-glance-py.macos.x86_64
Windows paraview-glance-py.windows.x86_64.exe

Usage

Run the executable. A new tab will open in your web browser with the application user interface.

Development

Build

This has only been tested with python3.

$ git clone [email protected]:KitwareMedical/paraview-glance-py.git
$ cd paraview-glance-py/
$ npm install
$ npm run build:release
$ cd server/
$ pip install -r requirements.txt

To build a standalone executable:

$ pip install pyinstaller

On Windows, also install pywin32:

$ pip install pywin32

Then package as a directory:

$ pyinstaller build/paraview-glance-py.spec

Or as a single file:

$ pyinstaller build/paraview-glance-py-onefile.spec

Run

Simply run the resultant executable dist/paraview-glance-py/paraview-glance-py.

Run web and server separately

For dev purposes, it is better to run the web and server as separate instances for debugging.

In one terminal, build the development version of the webapp:

$ cd paraview-glance-py/
$ npm run dev

In another terminal, run the server.

$ cd paraview-glance-py/server
$ python server.py --port 8181 --no-browser

After the python server starts up, visit http://localhost:9999/?wsServer=ws://localhost:8181/ws to view the webapp. If you get a blank screen, try clearing cache and then refreshing.

Troubleshooting

Library issues when running (linux)

For the prebuilt binaries, this is likely due to the automated build environment using a different version of certain libraries. The easiest workaround is to follow the instructions under "Development" above and build the application locally so pyinstaller can link against local libraries.

The application is still running after closing the tab

Right now the server is set to self-terminate after 5 minutes. Either kill the application manually or wait 5 minutes for the application to self-terminate. Multiple instances of the application will not interfere with one another.

paraview-glance-py's Issues

How to make the built webapp working with the server?

Hi,

I'm trying to build code, and I'm having troubles trying to use it with python server.
To built and start web and server instances, I followed instructions from documentation (and did not built a standalone executable)

Once server started (with python server.py), I have access to the web page at http://localhost:9999/ but the process step does not work and I'm guessing it is because no server is found.
Moreover, once server starts, it directly opens http://localhost:41692/?wsServer=ws://localhost:41692/ws . The front of this page is not the same than the one at http://localhost:9999/ and here, I can run the process step.

How can I make the server works with the built webapp ?

Thanks,

Error when executing remote tasks

Here is the error I got when executing remote tasks:

"ValueError('cannot reshape array of size 8388616 into shape (128,256,256)')"
"Traceback (most recent call last):

I use Engine.vti and itk 5.1.0

Default server port not correct - two ports are relevant

Lines 59 and 60 of server.py are incorrect:

paraview-glance-py/server/server.py

Line 59 in 26b9a10

wsurl = 'ws://{host}:{port}/ws'.format(host=host, port=port)

There are two ports that need to be recorded and reported to start the web and compute servers. The http:localhost:{port} that is running the webserver hosting the paraviewglance webpage and the ws:{port} that hosts the paraview server. Via lines 59 and 60, the program reports:

C:\src\ParaView-Glance-Py\server>python server.py --port 8181 --no-browser
Namespace(host='localhost', no_browser=True, port='8181')
If the browser doesn't open, navigate to: http://localhost:8181/?wsServer=ws://localhost:8181/ws
wslink: Starting factory
CRITICAL:twisted:wslink: Starting factory

This is wrong. The first instance of {port} should be 9999, in this case. The 8181 port is correct.

Hope this helps,

Release URLs are dead

In the project Readme, the URLs to download the stand-alone executables are dead.
Github stores other releases (suffixed with vessel) but I'm not sure if they are supposed to be the same.
