For instance: What are all naming conventions I need to be aware of? How should controller actions be structured and named?

问题 Background In order to speed up generating grouped summaries across multiple tables; as I'm doing most of that while in dplyr workflow, I've drafted a simple function that generates the desired metrics # Function to generate summary table generate_summary_tbl <- function(dataset, group_column, summary_column) { group_column <- enquo(group_column) summary_column <- enquo(summary_column) dataset %>% group_by(!!group_column) %>% summarise( mean = mean(!!summary_column), sum = sum(!!summary

问题 Given a situation such as the following library(dplyr) myData <- tbl_df(data.frame( var1 = rnorm(100), var2 = letters[1:3] %>% sample(100, replace = TRUE) %>% factor(), var3 = LETTERS[1:3] %>% sample(100, replace = TRUE) %>% factor(), var4 = month.abb[1:3] %>% sample(100, replace = TRUE) %>% factor())) I would like to group `myData' to eventually find summary data grouping by all possible combinations of var2, var3, and var4. I can create a list with all possible combinations of variables as

问题 I'm trying to setup an image recognition CNN with TensorFlow 2.0. To be able to analyze my image augmentation I'd like to see the images I feed into the network in tensorboard. Unfortunately, I cannot figure out, how to do this with TensorFlow 2.0 and Keras. I also didn't really find documentation on this. For simplicity, I'm showing the code of an MNIST example. How would I add the image summary here? import tensorflow as tf (x_train, y_train), _ = tf.keras.datasets.mnist.load_data() def
