QUESTION
I am trying to set up a WASM back-end for blazeface face detection model in a react app. Although the demo with the vanillajs can run it without any error for hours, in react it throws "Unhandled Rejection (RuntimeError): index out of bounds error" after leaving the cam open for more than 3-5 minutes.
Entire app crashes with this error. From the log of the error below, maybe it is related to disposeData() or disposeTensor() functions which to my guess, they are related to garbage collecting. But I don't know if it is a bug from the WASM lib itself or not. Do you have any idea why this might happen?
Below I provide my render prediction function as well.
...ANSWER
Answered 2020-Oct-25 at 14:42After using a tensor to make predictions you will need to free the tensor up from the devices memory otherwise it will build up and the cause a potential error you are having. This can simply be done using tf.dispose() to manually specify the place at which you want to dispose the tensors. You do it right after making predictions on the tensor.
QUESTION
In this code , I am not able to understand why the rotation is not in circular locus. This may be basic logic behind this but i can't understand why this so random locus.
I am rotating camera in orbital motion but it is not following it.
In my knowledge, i created a orbital motion camera and inverse of that is view matrix. So, view matrix will transform the world space for this result.Is there any fault in my thinking process ?
...ANSWER
Answered 2020-Jun-24 at 16:50If I understand your question, the problem you see is it looks like the camera is getting closer to and further from the Fs
The issue is the vertex data for the Fs are built so the top left front corner is at 0,0,0, from that they go +X 100 units (so 100 units wide), +Y 150 units (so 100 units tall), and +Z 30 units so 30 units deep
So then, when you draw them around a 100 unit circle their origin is the part you are positioning and you get this
The image is top down so the Fs are just a rectangle. The green circle is the local origin of each F, its local 0,0,0. The other vertices of the F are relative to that local origin so they are closer to the outer circle (the orbit of the camera) on one side and further on the other
You can fix it by moving the Fs -50 in X and -15 in Z. In other words
QUESTION
Am completely new to flask so pls forgive me if dumb question
I'm learning how to use flask and want display graphs generated by sigma.js.
When I open "svg-freestyle-renderer.html" directly by double-clicking on the file, it opens up and shows an interactable network graph with nodes and connections.
Now I want to view the same graph by accessing the html in a flask server but when I open the page, it only loads the background colour without the graph. I've triple checked all my files are in the right directory.
Is there a difference between opening a html file directly and accessing it through flask that I'm missing?
This is how I'm calling the html in my py file:
...ANSWER
Answered 2020-Jan-17 at 03:22Right click on your page in browser and click "Inspect element" and open "console". You'll see something like
Failed to load resource: the server responded with a status of 404 (NOT FOUND)
for all your files.
Put your js files in a directory named static or you can specify your own creating your app app = Flask(static_folder="src")
And in your templates use {{ url_for('static', filename='sigma.core.js') }} to access your js-files. You won't be able to open this page in browser directly from filesystem, but will it perfectly served by app.

QUESTION
I have 4 Orgs:
- Org1 -- 2 peer
- Org2 -- 2 peer
- OrgCam -- 0 peer, 1 client
- OrgView -- 0 peer, 1 client
Org1's peers have a chaincode installed on them that access some private data only available to Org1.
As a client of OrgCam, I want to access the chaincode installed on Org1's peers.
When I try to do that:
...ANSWER
Answered 2019-May-20 at 07:59I am a bit confused by your configuration, but I'll try to answer as best as I can.
Lets make it clear
A chaincode does not "belong" to an organization. A chaincode belongs to a channel and has particular endorsement policies.
Considering that, you could say a chaincode belongs to the peers that are member of the channel.
An organization can only interact with a chaincode if it possesses a peer that is member of the channel that has the chaincode.
Answer
You did not provide any information about your channel. Considering you error, I suppose you did not join the OrgCam peer to the channel in which Org1 peer(s) deployed the chaincode.
You OrgCam peer is not part of the channel, you cannot query the chaincode of the channel.
Moreover, you cannot use a OrgCam client certificate to interact with a Org1 peer, because the certificate is not known/accepted by the Org1 peers. Only Org1 explicitly defined clients can interact with org1 peers.

QUESTION
When I run this, I will check the database after submitting the form and all the values for the check boxes (smalltube, largetube, wakeboard) all say yes, even if its not checked.
any idea why?
The checkboxes should get the value yes or no from here
...ANSWER
Answered 2018-Oct-19 at 00:32It's because you are using a hidden input before the checkbox and checking if it is not empty.
Try check if the input name is set instead.
