QUESTION
I am trying to use the redisgraph-bulk-loader to load the dataset into the RedisGraph instance running in a docker container. However, it returns with IndexError: list index out of range
which I do not understand. I have read the documentation and my CSV files are valid.
I have opened an issue here.
Command :
$ redisgraph-bulk-loader DemoGraph --enforce-schema --nodes-with-label TBox import/nodes.csv --relations-with-type relations import/relationships.csv
Log :
...ANSWER
Answered 2021-Apr-20 at 15:54The error you're encountering occurs at this line - https://github.com/RedisGraph/redisgraph-bulk-loader/blob/master/redisgraph_bulk_loader/entity_file.py#L233 .
At this point, we are trying to retrieve the type specified after the colon in a specific field of a header line. As such, an IndexError
indicates that no colon was found in one of the fields.
Looking at relationship.csv
, I see that the header row ends with "properties__title","properties__uri","end__labels__002"
. These columns should have a colon-separated type, like the preceding fields.

I am using the classic titanic dataset to build a decision tree. However, I am not sure what goes wrong with the edges or branches that are almost invisible.
Here is the code for building the decision tree
...ANSWER

returns a list of artists (a list of Annotations). You can access the arrow and change their properties in a loop. Refer to https://matplotlib.org/api/_as_gen/matplotlib.patches.FancyArrowPatch.html#matplotlib.patches.FancyArrowPatch for a list of the properties that you can change.
I don't know why the arrows don't appear in your case, but I would start by playing with their colors and width.
QUESTION
I am a beginner at working with CNNs.
So, I am building a 2D convolutional neural network that predicts brain tumor type and have a question about NumPy arrays. The input-shape of my model is (1, 512, 512) as (channels, img_height, img_width). The 4th dimension is num_images which seems to be automatically defined by TensorFlow. This is just a quick background. I have 3064 ".mat" extension files with MRI scans of brain tumors. Everything is setup. I converted ".mat" files into numpy matrices and appended the entire list of matrices in a single numpy array to pass as input for the CNN. I also have the corresponding labels (index-linked to the images when passing input into the model) as a numpy array. All the numbers are of float type in both images and labels.
Again, my input shape is (1, 512, 512). However, when fitting my model I get the following error:
ValueError: Error when checking input: expected conv2d_130_input to have shape (1, 512, 512) but got array with shape (79, 512, 512)
So, I am slicing my NumPy arrays to create train_images, train_labels, test_images, test_labels. I have verified the length of each both train and test sets with there labels match. They are also arrays, I checked multiple times. And this is a value error. So, how do I fix this?
I don't even know where the input shape became (79,512,512). I have a loop to convert f"{n}.mat" images to a matrix. I am using 100 images to test and have 80 train and 20 test. I think the mistake is here, the input shape is (channels, img-hght, img-wdth), but the number of images left to train is being placed in the channel's value instead. So, the input is being placed as (num_images, img-hght, img-wdth). This is wrong and should be changed, but I don't know how to do it. Or, I could be wrong and what I said might not make sense. I am providing all the code, running it on Colab. Make sure to change the image paths if you download the code and want to run it in order to help me out. Thanks a lot!

QUESTION
We've recently updated Newtonsoft.JSON and another Nuget package, SKGLExtension, across both our WPF and Excel add-in products.
All of our referenced projects use the Newtonsoft.JSON.dll version 11.0.0 nuget package.
Both the WPF and Excel products reference an engine .dll, which then reference the SKGLExtension which uses Newtonsoft.JSON.dll.
When the Excel add-in is installed via MSI and run, we get this binding error:
...System.IO.FileLoadException: 'Could not load file or assembly 'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)'
ANSWER
Answered 2018-Jul-06 at 02:33After exhausting our options, we have unfortunately had to remove the nuget reference to the SKGLExtension package. Fortunately, we were able to compile the SKGL library from source against the Newtonsoft.Json package version 11, which has resolved the issue. It would have been nice to find a better solution, though
QUESTION
I have an application which has a license key function.
The user gets their license key, then type it into the TextBox where the license key is supposed to go, and if the license key is valid, they get taken to the main form, where all of the features are.
Now, to make my program more secure, I need to be able to check that the user has definitely typed in their license key, and they haven't done something like delete (by decompiling) the license key form so they can gain access to the main form where all of the features are.
Note: My license keys are stored on a server.
How would I check that the user has definitely typed in the license key?
Below is the code.
AddLicense.vb:
...ANSWER
Answered 2018-Apr-28 at 18:17I believe what you want is to stop users from decompiling your program and removing the license key form entirely...
Unfortunately, it's impossible to stop that, as long as a program can be run on an ordinary computer, it can be decompiled, otherwise, it would be impossible for the processor to process it.
This means, that it would be possible to remove the relevant instructions for that, and C# and VB is easy to decompile - tools like dotPeek get valid source code (it won't be exactly the same as the original, but still readable and runs like the original) just with a click.
Keep in mind that even proper commercial programs made by whole companies have this problem.
So, what could you possibly "do"? Well, I only really have two suggestions... but they won't work too well.
One only makes it harder and the other one requires access to the internet all the time.
ObfuscationObfuscation essentially makes the code harder to read after decompiling, however, it won't stop people from deleting the form, it will just make it slightly harder.
I posted it as an option because it will make the code very confusing when recompiling and it might be helpful to "protect" it a bit more. However, just remember this: "It's a weak layer of defence for a weak attacker."
An obfuscator you could use is Eazfuscator.NET, that webpage I sent also has a description of essentially what it does and how to use it - it may be worth taking a look at.
Online ServersThis one requires a connection to the internet... but, it's the only other option you have at all - it's either this or... able-to-get-rid-of-product-key.
Essentially, in this idea, you make a server do all the work that the application has to do and then return the result of it.
Imagine the user's computer is a server. Their "server" runs the code, and so the code is on their "server" (otherwise it has nothing to run) and everything is processed on their server. Now, if you run it on your server, all the code is on your server and your server only returns the result, meaning, they can't get at the process that provides that result.
In the end, this would mean that the application physically would not be able to do anything without a license key, since the only way it can get its data processed is via the server, and the server won't process the data without a product key.
The only downside to this is that you must have an internet connection and if the internet connection is slow - the program will be slow.
Since you want to know how to do this in vb.net taking a look at ASP.NET may help, but it's really designed to make a full-website - not to just process a few tasks.
I can leave it up to you how you would want to approach this task but here's one way of doing this:
The code below will make a "request" to a certain URL and then get the result back - with this, you could make it so when it goes to that URL the server processes the data given (including the product key) and returns back a result.
QUESTION
How can I use my database with another computer without changing the path?
I'm using this path
...ANSWER
Answered 2017-Aug-27 at 09:31Do not use the path you are now using for your database file. It is a location used to store your VS project in development. When you deploy your application, you should not use any of your development folders.
You should use a dedicated folder for your database, like
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)
Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData)
Or you can use the folder your app is installed in, provided that the every user has read/write access to it (it should not be e.g. in ProgramFiles
)
