Cannot convert binary image to label if applied on a cropped image

$
0
0

Dear KNIME experts,

I have recently created a workflow that aims to use the interactive annotator to manually select a rectangular region of interest. This region is used to crop the image and to subsequently process/analyse only the manually cropped region. However, when I try to apply the global thresholder and the "image to labeling" node, I failed to obtain the label. Interestingly this works on the uncropped image. I have no idea why the "image to labeling" cannot be applied on a cropped image. The problem does not appear to be related to different images sizes in the column: if I apply the workflow after filtering to one row, the problem persists.

Would be very grateful for any advise. Thanks in advance. An example workflow with embedded images is attached.

File Reader Error While analyzing file:

Having some difficulties using the Knime File Reader node on a Macintosh.

I've tried several URLs that seem to work OK from the Browser on this workstation.

For example:

http://archive.ics.uci.edu/ml/machine-learning-databases/adult/adult.data

Does not work and gets I/O Error while analyzing file: Can't access 'http://archive.ics.uci.edu....

This HTTP:// URLs do not seem to read.

If I change the url to an HTTPS:// URL  Things see to read OK.

I belive that the HTTP version of the URL worked on previous versions of knime.  Not working now.

Thoughts?

SVD - Singular Value Decomposition

I could not find a SVD function in KNIME. Does anybody know if there is such a module in KNIME? I need it for directional reduction in text mining projects. Most every Text Mining / Text Analytics tool has such a data reduction module... If it does not exist, what is the process to follow to request it from the KNIME development gurus. 

Thanks,

Delen

SQL OPENQUERY to Progress Database

$

Hi..

I am trying to use KNIME to access tables within a Progress Database which is succesful when retrieving the data but not when getting the SQL Types.

All dates are shown as timestamps, decimals as numbers(30,10), strings as varchar(255) etc..

The problem is there are some 2,000 columns for 12 tables and to enter these would be very time consuming considering I have already recreated the tables under SQL.

The purpose of the project is to read from Progress and then Insert/Update the tables in SQL similar to a T-SQL 'MERGE" script.

Any suggestions on this?

Setting fixed axis ranges in jfreechart nodes (Line chart)

$

Dear users,

is there a possiblity to specify the axis range in jFreeCharts (particularly Line charts) to have a fixed value for the maximum Y  value to be displayed? Could this be controled by a flow variable? I could not find any option or variable field to do this. It works easily with R view and matplot, but R view nodes need longer computational times and are more difficult to configure for users with no R knowledge.

Thanks in advance for any advise.

Stefan.

Distance between two columns

Hi all,

I'm totally new to KNIME, please excuse me if the question is too silly but I've been unable to come up with a solution for this...

I have a table with two columns, each one containing n-dimensional vectors expressed as a collection of doubles. Is there any node capable to insert a third column into the table, containing the euclidean distance between the two vectors at each row?

Best regards, and thank you for your help,

Deprecated DatabaseReaderConnection Class - Alternative?

Hello Knime community,

I'm developing a node which uses a DatabasePortObject and the DatabaseQueryConnectionSettings.

With the settings I want to create a BufferedDataTable in my execute method. 
Currently I'm working with the DatabaseReaderConnection which works perfectly fine.
However, I saw that this class is deprecated. (At least eclipse says this) So which new class will be used to get a BufferedDataTable from a DatabaseConnectionSettings object?

In advance thank you very much for your answers.

wrapped node - always default value used

$

Dear,

I have a "Value Filter" quickform node inside a wrapped metanode. This value filter is populated with a list from a SQL query. 

Whatever selection I make on the webportal in this value filter, it is not used, but instead the default value of the "Value filter" is always used...
I already have included all workflow variables to be visible outside the wrapped node, but this does not solve my problem...

What am I missing?

I am using org.knime.core version 3.1.3

 

DL4J - how do you verify the GPU is being used?

$

I am working on the DL4J package and nodes. I have got it working and I am trying to integrate with GPU: 4NVIDIA GRID K1's. I have set up the proper backend installations which DL4J connects to: CUDA driver and CUDA Toolkit v 7.5. After that, I go into the KNIME preferences and check 'Use GPU" for DL4J. However, in my tests, running on the GPU takes more time than running on the CPU (14 times longer). Surely, there is some error. I know that the GPU is not the issue because with the same backend installations, I have a deep learning program running in Python, and it runs faster on the GPU than on the CPU. So unless some other dependencies need to be installed, I think there is some issue with how DL4J in KNIME is connecting to and using the GPU - some disconnect exists there.

 

I am on a Windows Server 2012 system.

 

I have attached the workflow I am using. The dataset used by the topmost node (Income) is found here: https://archive.ics.uci.edu/ml/datasets/Adult.

 

If anyone has experienced setting up GPU use with DL4J, any help would be appreciated. Thank you.

How to read Japanese file (not using UTF-8 codepage) in file reader node?

I am trying to read a file containing Japanese character in KNIME workflow using file reader. None of the built-in codepages (UTF-8, UTF-16 etc) could read this file properly. Then I opened this file in Excel and Excel used 932: Japanese (Shift-JIS) to read the file fine. Is there anyway, I can use this code page to read the file in my KNIME client? Any setting I need to change so that file reader node will display this character set?

Is there anything I need to do in the Linux server to make this workflow run successfully in the KNIME server?


Table to JSON - to a predefined schema

I would like to output values from a table to a JSON data schema. At the moment, I have no control over the structure of the JSON except for adding specific values. I want to map from table to names in the data schema the same as I do when I read a JSON using JSON Path to map out the values I want to retrieve.

Is there a version of JSON Path which allows me to add a JSON as output and map to it from table? Additionally, I would like to add static values which do not come from the data values from the table.

Thanks, Matt

I have a workflow that outputs to an SQL table the issue I have is I get the “Error while adding rows #101 - #201, reason: String or binary data would be truncated.”  The only way I have found to fix this is to use a column filter to remove some fields start to run the Database writer which now does not error cancel the operation, put the excluded fields back re run the Database writer and it will work. I have made no changes what so ever to the data or the writer settings, has anybody experienced this and is there a fix?I

Dear,

I am running Knime WebPortal Lite version 4.3 on Apache Tomcat (TomEE)/7.0.55 (1.7.1) with Java 1.8

It is working fine for the workflows, but when I go to the administration interface, I get the following error:

"Admin pages not available. Error: 500 Internal Server Error""Could not load status data from server. Error: 500 Internal Server Error""Could not load license data from server. Error: 500 Internal Server Error"

In the Tomcat logs I see this error:    

"INFO          com.knime.enterprise.server.application.LoginManagerImpl checkLicense                     : Message for invalid or missing Webservice license sent to user"

and

"GET /com.knime.enterprise.server/rest/v4/admin/license?_=1471607827686 HTTP/1.1" 500 75

Apparently, I also cannot login to the server anymore from the knime client with a "connect time out" error on the client side, and the same error on the server:

Where should I start looking at?
