I am trying to create a Model, but i'm getting a RuntimeError "Boolean value of Tensor with more than one value is ambiguous". I've searched already on other posts about this but could find a working solution so here is my own try.
I am following a tutorial, which is working with the tutorial set of Data. The code looks as follows:
...ANSWER
Answered 2022-Feb-16 at 10:12Short answer:
Remove the Variable()
Explanation:
I believe your answer is in you question. If you don't know what Variable is, why are you using it? But more importantly you are importing it from tkinter which is an interface package and I'm pretty sure that's not what you want.
What you want is to use the one from torch.
I was looking for it in the doc but it is actually deprecated, the Variable() API from torch now returns a Tensor so it is not useful anymore.

I need a bit of advice here.
I have the following chart:
I would like to start the chart XAxis at 00:00 and end at 23.59, but I still have to plot the last point of the previous day and first of the next day (so that the line/curve continues off), but not extend the chart view to include these points. I have drawn lines onto where I would like the chart to start and finish.
Anyone have any idea how I can achieve this? It is a daily tide chart, so only needs to show the curve of a single day.
Here is the code I currently have:

QUESTION
I develop an iOS app using Swift.
I use the following method below to access an login ENDPOINT with PUT method.
...ANSWER
Answered 2021-Dec-27 at 16:18I find out the fix for my problem.
I was using "http://MY_ENDPOINT/validaResenha" in my constants file instead of using "https://MY_ENDPOINT/validaResenha".
After add the "s" to "http" letter (it becomes "https") everything starts to work for me.
The strange part is that GET and PUT methods works fine because of the redirect from HTTP to HTTPS, but in the case of POST calls, I got this error.
It's fixed now.

QUESTION
I'm currently working on a simple neural network using Keras, and I'm running into a problem with my labels. The network is making a binary choice, and as such, my labels are all 1s and 0s. My data is composed of a 3d NumPy array, basically pixel data from a bunch of images. Its shape is (560, 560, 32086). However since the first two dimensions are only pixels, I shouldn't assign a label to each one so I tried to make the label array with the shape (1, 1, 32086) so that each image only has 1 label. However when I try to compile this with the following code:
...ANSWER
Answered 2021-Nov-28 at 15:47The ValueError occurs because the first dimension is supposed to be the number of samples and needs to be the same for x and y. In your example that is not the case. You would need datax to to have shape (32086, 560, 560) and datay should be (32086,).
Have a look at this example and note how the 60000 training images have shape (60000, 28, 28).
Also I suspect a couple more mistakes have sneaked into your code:
- Are you sure you want a
Conv1Dlayer and notConv2D? Maybe this example would be informative. - Since you are using binary crossentropy loss your last layer should only have one output instead of two.
QUESTION
I've been working on a Neural Network recently but everytime I try to compile the model, I get a SIGKILL which by looking at Activity Monitor, is from a memory error. My data is very large but it's not a part of the problem because I tried taking a tiny part of it but I still get the same error. This is the code I'm using:
...ANSWER
Answered 2021-Nov-27 at 21:55you add dropout layer in your model.
Dropout is a technique where randomly selected neurons are ignored during training. They are “dropped-out” randomly. This means that their contribution to the activation of downstream neurons is temporally removed on the forward pass and any weight updates are not applied to the neuron on the backward pass.
