QUESTION
I have a data frame that is indexed from 1 to 100000 and I want to calculate the slope for every 12 steps. Is there any rolling window for that?
I did the following, but it is not working. The 'slope'
column is created, but all of the values as NaN
.
ANSWER
Answered 2021-Jun-14 at 15:14- It's not necessary to use
.groupby
because there is only 1 record per day. - Don't use
.reset_index(0, drop=True)
because this is dropping the date index. When you drop the index from the calculation, it no longer matches the index ofdf
, so the data is added asNaN
.df['Close'].rolling(window=days_back, min_periods=days_back).apply(get_slope, raw=True)
creates apandas.Series
. When assigning apandas.Series
to apandas.DataFrame
as a new column, the indices must match.
QUESTION
Dears, I have a jersey - spring api deployed on apache tomcat 9.0.46. (Jersey to handle restful services JAX-RS and Spring to handle all my beans{controllers, DAO, SessionFactory, JPA etc...}). Everything works fine on tomcat 9 on windows... When deploying the exact same war in ubuntu tomcat 9.0.46, the ContextLoader is getting triggered 3 times and I have all my singletons instantiated 3 times. I'm deploying the api on tomcat ports 80 and 443 (https - godady certificate). once I start tomcat the war is deployed and ports 80 and 443 get started (netstat -tulnp | grep java) and I see in log all singletons instantiated. (pool-2) Applicationcontext class my custom spring @Configuration class and it is getting triggered and DB is accessed without any issues
...ANSWER
Answered 2021-Jun-14 at 12:43I have managed to figure out the problem. The issue was related to tomcat configuration in /conf/server.xml. Multiple Hosts will trigger the context loader to be triggered for each. I was keeping the default appBase to webapps for all host thus triggering the ContextLoader of each my war for each host. Another reason the ContextLoader will triggered multiple times as well is defining the option inside unless you need to load something external to your war. I recommend reading specs: https://tomcat.apache.org/tomcat-4.1-doc/config/host.html
QUESTION
Recently I have been trying to convert .doc files into a new format, so that it is easier to work with the data. So, I decided to convert the .doc files to .docx files because there is a lot of flexibility from there, and I thought this task would be easy. However, I thought wrong. I am currently trying to use Win32 to access Word and for some reason it isn't working. Here is my code:
...ANSWER
Answered 2021-Jun-14 at 09:33You are almost there and need to change just a few little things:
- No need for
Activate()
, you can omit this - I think that your regular expression does not do the job correctly
- You should quit the Word application after saving the file
So this should work:
