roboflow not generating new version - roboflow

Please help me, when I generate a new version of my dataset, roboflow takes a long time with only 14 images and then generates a new empty version with no images.

Can you help me understand your user flow? When Generating a new version of a dataset you should be taken to the "Generating New Version" page where you have the option to add more source images, rebalance train/test/split, preprocess, augment, and generate.
Addressing the images you attached with unused classes 3-7, if the question here is to remove the unwanted classes, you can do this by clicking Add preprocessing step and selecting modify classes to remove or override a name

Edit Photos via Photoshop on a server

I wart to create a web app where a user enters certain data via a form and then receives a custom rendered image. The image is from a smart object in a psd. It's kind of like a mock-up which definitely requires needs some photoshop filters to be properly rendered.
This should all happen in real time and should be doable from my understanding since the rendering of a single images doesn't need much computing power
I've done some research and haven't really found a solution the matches my problem. Is it necessary to run Photoshop on a server and then remotely run a photoshop script and then upload the generated image somewhere else?
I've used The After Effects Plugin Template by DataClay in the past which offers similar functionality but for video.
Looking forward to hearing your ideas.
Thanks
You can use the Dataclay plugin to handle still image exports out of After Effects. Make a single-frame duration composition in After Effects and rig the layers with the Templater plugin. Then use the PNG Sequence output module to render out a single frame.
From Dataclay's forums:
Exporting
A few extra steps are required to correctly render a project file as a PNG sequence using Templater. By default, a file rendered as a PNG sequence will have the frame number appended to the end of the file name, i.e.:
filename.png00000, filename.png00001, filename.png00002, etc.
In order to designate where in the filename the frame number should be added, we’ll need to use the output column. First, add a column named output to your data source. Next, add a filename with a set of brackets with five # signs to designate where the frame numbering should be added. For example:
filename[#####] would result in filename00001.png
or
[#####]filename would result in 00001filename.png

Deletion of module columns/attribute not visible on a given View

I have been given the task of creating a DXL script. First problem is that I have never used DXL before, even though I have many years experience with DOORS itself. I have been surfing the Net to seek guidance on my particular problem. I also have a few specimen DXL scripts for reference.
My new client requires that for each View of a given Module, of which there are many Views, new "reduced" Modules are to be produced reflecting each View.
By "reduced", I mean that these new Modules are to contain nothing that isn't actually needed for that View., i.e. Columns, Attributes etc. These new Modules will only have the single View.
So, the way forward as I see it, is to take copies of the single master Module, one for each View, rename those copies to reflect a given Master Module/Required View, select that required View in the given copy Module and then delete everything that is not needed by that View, i.e. available Columns, Attributes etc.
This would be simple if I had the required DXL knowledge, which I am endeavouring to pick up as fast as I can.
If at all possible, this script has to be generic and be able to work upon any of the master Module copies to produce the associated "reduced" Module reflecting a particular View.
The client aims to use the script periodically for View archiving (I know, that's the way they want it).
Clarification
Some clarification of what I believe is required, given the following text from my original question:
If at all possible, this script has to be generic and be able to work upon any of the master Module copies to produce the associated "reduced" Module reflecting a particular View.
So, say there are ten views of the master Module, outside of the DXL script, I would copy the master Module ten times, renaming each copy to reflect each of the ten views. Unless you know different, each of those ten copies will reflect the same “Absolute Number”s as are in the master Module, so no problem there?
So, starting with the first of the copied Modules, each named to reflect the View it will eventually represent, its View would be set from the ten Views available to it, that which matches its title.
The single generic DXL script would then be run against that first copy Module, the aim being to delete everything not actually needed for that view, i.e. Attributes, Columns etc. Would some kind of purging command be required in the script for any aforementioned deleted items?
The single generic DXL script would then delete ALL views from that copy Module. The log that is produced when running the script also needs capturing, but I’m not sure whether this should be done from within the script, if possible or as a separate manual task outside of the script.
The aforementioned (indented) process would then be repeated, using the same generic script, against the remaining nine copied Modules. The intension is to leave us with ten copy Modules, each one reflecting one of the ten possible Views, with each one containing only the Attributes, Columns etc. required for that View.
Creating a mirror of a module with this approach is not so easy IMO. Think e.g. about "Absolute Number". If the original module contains the numbers 15 (level 1), 2000 (level 2), 1 (level 1), you will have to create 2000 objects, purge 1997 of them and move them to the correct place.
There is a "duplicate" tool at https://www.ibm.com/developerworks/community/forums/html/topic?id=43862118-113d-4eac-b3f1-21d3b73959d1 which tries to do this, but as stated there, this script is said not to work correctly in all situations.
So, I would rather use the approach "string clipCopy (Item i); string clipPaste(Folder folderRef)". Should be faster and less error prone. But: all Out-Links will also be copied with this method, you will probably have to delete these after the copy or else the link target module(s) will have lots of In-Links.
The problem is still not so easy to solve, as every view might have DXL columns that rely on some or other attribute, and it might contain DXL attributes which again might rely on sth else. I doubt that there is a way to analyze DXL code "on the fly" and find out which columns may be deleted.
Perhaps a totally different approach would be feasible: open each view and create an export to Excel, this way you will get rid of any dynamic dependencies. Then re-import the excel sheet to a new DOORS module. You will still have the "Absolute Number" problem, but perhaps you can make a deal that you will have a pseudo attribute "Original Absolute Number" and disregard the "new" "Absolute Number"'
Quite a big task for a DXL beginner....
Update: On second thought, perhaps you might want to combine these approaches
agree with your employer that you will use an alternative attribute for Absolute Number
use a loop like Russel suggested, when creating objects remember that objects might have to be created "below" or "after" its predecessor or sibling
for DXL attributes do not copy the DXL code but the actual current value of the object
for DXL columns create pseudo attributes _ and create a new view that uses these pseudo attributes instead of the original value
Copying the entire module, then deleting everything not in that view, seems worse than just copying the things you need from each particular view.
I would take the following as the outline of your program:
for view in main module do {
for column in view do {
Find attribute for each column and store (possibly in a skip list?)
Store name of column
}
create new module
create needed types / attributes in new module
create new view in new module
for object in main module {
create object in new module
for attribute in main module {
check if attribute is in new module {
copy info from old object to new
}
}
}
}
Each of these for X in y loops should be in the DXL reference manual in some for or another.
If you need more help, let me know!

NiftyNet 'evaluation' action output is incorrect

I'm trying to use the new 'evaluation' action after inference to generate some metrics for my output. However, the .csv files just show scores of '0' for average_distance and '1' for Jaccard and Dice for each of my data volumes. I can't seem to find any documentation for the evaluation action, so I'm not sure what I'm doing wrong. Also, the --dataset_to_infer=Validation option doesn't seem to work, both inference and evaluation are being applied to all data rather than just the validation set.
Thanks!
For the evaluation issue, we're working on the documentation. The dataset_to_infer option is only tested for the applications in NiftyNet/niftynet/application; applications from the model zoo are not upgraded to support it yet (please file an issue with more details https://github.com/NifTK/NiftyNet/issues if you believe it's a bug).
For the time being, pointing directly to the inference result in the config.ini worked for me.
e.g.
[inferred]
csv_file = model_dir/save_seg_dir/inferred.csv
I believe this file is not found currently and then evaluation defaults to comparing labels to labels. See the issue on GitHub.

Processing multiline events from a text file in Dataflow

I am attempting to build a dataflow pipeline to process a text file which contains events that span multiple lines. The dataflow SDK TextIO class assumes each line is a new event.
My plan is to create a new TextReader and register it with the DataPipelineRunner. This new reader will know how to aggregate the multiple lines into a single line.
I am pretty sure that this approach will work but I am wondering if this is the right way to do it or if there is a simpler solution?
The text I am trying to parse is:
==============> len:45 pktype:4 mtype:2
SYMBOL: USOCSTIA151632.00
OPEN_INT: 212
PR_OPEN_INTEREST: 212
TIME_STAMP: 04/10/2015 06:30:17:420 val:1428661817
The result should be the last 4 lines concatenated together and the first line dropped.
Best regards,
Peter
Note that TextReader is an internal implementation detail class, so subclassing it would be highly discouraged and challenging to do properly.
The recommended way to define a new file-based format like yours is to subclass FileBasedSource using the user-defined source API.
In your case, I would recommend to base your class on the LineIO example from documentation, and wrap the LineReader defined there into your own class which would use LineReader as a helper for reading individual lines, but:
In startReading() it would skip until the line starting with "====>"
In readNextRecord() it would read lines until the next "====>" and bundle them into a single record.
Please make sure to carefully read the documentation to FileBasedSource and FileBasedReader: the parallelization mechanism relies on the consistency properties described there, which your format has to satisfy, for ensuring that records are not duplicated or omitted on the boundaries between adjacent processing shards. XmlSource tests are a good example of how to unit-test these properties.
Please tell us how it goes and report back with any problems or questions - we are very interested in feedback on this API.

Is it possible to combine two .po translation files together?

We have two .po files, each from different branches of a piece of software.
We need to combine these into a single .po file.
There are duplicates between the two files, and the ideal handling would be for one file's strings to be favoured (consistently).
We have a SUSE system so the --output-file doesn't seem to have the behaviour of ignoring/merging duplicates which the Sun version has according to a man page I found from a web search. (We do not have a Sun machine handy!)
What you are looking for is the msgcat util, it concatenates and merges the specified PO dictionaries.
This is part of gettext utils, for more information please consult gettext manual page on msgcat.
you can use poedit.
To merge your current po-file, you must to open it and click:
Catalog > Update from POT-file.
Set the filter to all files and select your second.po file
Poedit will show you new & obsolete strings
I use msgmerge:
msgmerge [old_file.po] [new_file.po] > output.po
It works for me, but be aware that it does a silly merge, it is, it discards the entries in the old_file (new file items overwrites old one items).
