Looking at your error, the 16 GB are referring to the graphics card, not the ram.

As far as I know, using colab-pro enables you to use a graphics card with up to 16GB of VRAM.

You can check the VRAM amount by running the following code.

NO!!!!

In your forward method you x.view(-1) before passing it to a nn.Linear layer. This "flattens" not only the spatial dimensions on x, but also the batch dimension! You basically mix together all samples in the batch, making your model dependant on the batch size and in general making the predictions depend on the batch as a whole rather than on the individual data points.

Instead, you should:

Error "Unknown label type: 'continuous'" when I use IterativeImputer with KNeighborsClassifier

Asked 2021-Jun-05 at 18:31

I want to do a multiple imputation with IterativeImputer.

Here is the dataset (the original is from https://www.kaggle.com/jboysen/mri-and-alzheimers) :

alz_df_imp_categorical

The variables to impute are "educ" and "ses". As they are categorical I've choose to use a classifier (KNeighborsClassifier from sklearn). Predictors are continuous (except "sex").

This is the code :

...

ANSWER

Answered 2021-Jun-05 at 18:31

I just understood why it does not works. It's because IterativeImputer works only for continuous variables. So, apparently you can't apply multiple imputation for continuous variables with IterativeImputer. There is discussion about this here.

I saw it's possible to do simple imputation with categorical variables in python. However, it does not seem possible to do multiple imputation with this type of variables (anyway, I did not find).

QUESTION

Streamlining cleaning Tweet text with Stringr

Asked 2021-Jun-05 at 11:17

I am learning about text mining and rTweet and I am currently brainstorming on the easiest way to clean text obtained from tweets. I have been using the method recommended on this link to remove URLs, remove anything other than English letters or space, remove stopwords, remove extra whitespace, remove numbers, remove punctuations.

This method uses both gsub and tm_map() and I was wondering if it was possible to stream line the cleaning process using stringr to simply add them to a cleaning pipe line. I saw an answer in the site that recommended the following function but for some reason I am unable to run it.

...

ANSWER

Answered 2021-Jun-05 at 02:52

To answer your primary question, the clean_tweets() function is not working in the line "Clean <- tweets %>% clean_tweets" presumably because you are feeding it a dataframe. However, the function's internals (i.e., the str_ functions) require character vectors (strings).

cleaning issue

I say "presumably" here because I'm not sure what your tweets object looks like, so I can't be sure. However, at least on your test data, the following solves the problem.

How to input user images to predict with Tensorflow?

Asked 2021-Jun-03 at 03:15

For my project, I am using tensorflow to predict handwritten user input.

Basically I used this dataset: https://www.kaggle.com/rishianand/devanagari-character-set, and created a model. I used matplotlib to see the images that were being produced by the pixels.

My code essentially works with training data, but i want to up it up a little. Through CV2, I created a GUI that allows users to draw a Nepali Letter. After this, I have branching that tells the program to save the image inside the computer.

This is a snippet of my code for it:
