QUESTION
When using ls -l
, I noticed that directories start with 2 hard links, and gain one for each subdirectory. I understand that the current directory link .
counts as one link and the parent directory link ..
of each subdirectory counts as a hard link, but:
Why don't subfiles count towards hard links when subdirectories do?
Why does the parent directory link
..
count as a hard link for both this directory and the parent directory?

ANSWER
Answered 2021-Jun-15 at 11:40You are referencing a FileInfo

object, so filename.name.startswith('cop_ ')
should work.

ANSWER
Answered 2021-Jan-29 at 04:04In my opinion, the CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE
setting seems to be wrong.
you can check docker-compose.yaml
or core.yaml
- I will explain fabric-samples/test-network as targeting according to your current situation.
- You can check in
CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE
in docker-compose.yaml - Perhaps in your case(fabric-samples/test-network), the value of
${COMPOSE_PROJECT_NAME}
was not set properly, so it was set to_test
. - Make sure the value is set correctly and change it to your network name.
QUESTION
When running the first "almost MWE" code immediately below, which uses conditional panels and a "renderUI" function in the server section, it only runs correctly when I comment out the 3rd line from the bottom, observeEvent(vector.final(periods(),yield_input()),{yield_vector.R <<- unique(vector.final(periods(),yield_input()))})
. If I run the code with this line activated, it crashes and I get the error message Error in [: subscript out of bounds
which per my research means it is trying to access an array out of its boundary.

QUESTION
I'm trying to create a multi-page pdf using FacetGrid from this (https://seaborn.pydata.org/examples/many_facets.html). There are 20 grids images and I want to save the first 10 grids in the first page of pdf and the second 10 grids to the second page of pdf file. I got the idea of create mutipage pdf file from this (Export huge seaborn chart into pdf with multiple pages). This example works on sns.catplot() but in my case (sns.FacetGrid) the output pdf file has two pages and each page has all of the 20 grids instead of dividing 10 grids in each page.
...ANSWER
Answered 2021-Jun-14 at 17:16You are missing the col_order=cols
argument to the grid = sns.FacetGrid(...)
call.
