Ruby on Rails: Cannot Activate tmail




Gem::LoadError: can't activate tmail (= 1.2.3.1), already activated tmail-1.2.7.1. Make sure all dependencies are added to Gemfile.

I get this when I run a certain rake task. I've added it to the Gemfile, and I've already run gem uninstall tmail and gem install tmail.


gem uninstall tmail


gem install tmail

After updating your Gemfile always run bundle install.


Gemfile


bundle install



Also, when bundle install not help, try deleting your Gemfile.lock (file) and then do bundle install.


bundle install


bundle install



When that not fix your issue try to run bundle update for resolving dependencies, but that command can update all gems, so be careful with this task.


bundle update

PySpark count values by condition

Image
Clash Royale CLAN TAG #URR8PPP PySpark count values by condition I have a DataFrame, a snippet here: [['u1', 1], ['u2', 0]] basically one string ('f') and either a 1 or a 0 for second element ('is_fav'). What I need to do is grouping on the first field and counting the occurrences of 1s and 0s. I was hoping to do something like num_fav = count((col("is_fav") == 1)).alias("num_fav") num_nonfav = count((col("is_fav") == 0)).alias("num_nonfav") df.groupBy("f").agg(num_fav, num_nonfav) It does not work properly, I get in both cases the same result which amounts to the count for the items in the group, so the filter (whether it is a 1 or a 0) seems to be ignored. Does this depend on how count works? count 1 Answer 1 There is no filter here. Both col("is_fav") == 1 and col("is_fav") == 0) are just boolean expressions and count doesn't really care about their value as long a
