Set up Hugo for DTB and partly sth I’ll call NTB, which is non-work stuff.
So far Hugo is 110/10.
Old one for now is here.

setUp() and tearDown() methods in unittests get executed before/after each test method!
The dictionary with the datasets is a global dictionary, which means that you can’t register_coco_instances() in separate unittests in the same file!
This worked:
if Constants.TRAIN_DATASET_NAME in MetadataCatalog.data:
MetadataCatalog.remove(Constants.TRAIN_DATASET_NAME)
MetadataCatalog.remove(Constants.TEST_DATASET_NAME)
DatasetCatalog.remove(Constants.TRAIN_DATASET_NAME)
DatasetCatalog.remove(Constants.TEST_DATASET_NAME)
Through IDE settings one can configure whether one or multiple visual guides are shown, and the actual number of characters is configured through Settings -> Code Style.

Squash commits into one with Git - Internal Pointers (link by SO):
# Merge the last 7 commits into one
git rebase --interactive HEAD~[7]
# Merge the commits from that commit hash
git rebase --interactive 6394dc
In the latest one, the commit hash is “the hash of the commit just before the first one you want to rewrite from.”
Practically, assuming I want to squash together the a ones, I’d do git rebase --interactive B as it’s the one immediately following the ones I need.
commit a1 (latest/newest)
commit a2
commit a3
commit B
commit C
When actually doing the squashing, set squash in front of the commit lines to squash.
In the next screen, leave only the commit message(s) needed.
I love how it uses vim for this! Very interesting way to do an interface.
flake8 file.py shows issues;
black file.py applies black.
black --line-length=79 file.py applies the line length as per PEP8.
Pycharm uses 119 characters as limit, coming from Intellij I think; officially PEP8 recommends 79.

My blog takes minutes to be generated, this DTB is not far from it either. I heard Hugo is fast, and I dislike most of what’s on my blog, the logical thing seems to burn it to the ground and start from zero using Hugo.

When I’m in the directory with the test_xy.py files, running python3 -m unittest runs all of them. I can also do python3 -m unittest test_xy for that file, and python3 -m unittest test_xy.TestXY.test_specific_thing.
Found this, and it’s freaking awesome: Debugging by starting a REPL at a breakpoint is fun
Sample from there:
def make_request():
result = requests.get("https://google.com")
import ipdb; ipdb.set_trace()
There’s the default pdb, there’s ipdb that has to be installed.
Adding
import ipdb; ipdb.set_trace()
anywhere in the code launches a typical debug window that can be used to look into the vars etc.
Just used this for the first time to debug a python program that was running on a remote server and failing, but not locally.
SO much better than print(f"XXX {i}") and friends!
Nice tutorial about its usage: Better Python Debugging With IPDB

My main issue with Enum classes was that serialization is weird, especially if you’re dumping parameters. Tried again, found this: python - Serialising an Enum member to JSON - Stack Overflow
TL;DR class EnumDerivedClass(str, Enum)
import json
from enum import Enum
class LogLevel(str, Enum):
DEBUG = 'DEBUG'
INFO = 'INFO'
print(LogLevel.DEBUG)
print(json.dumps(LogLevel.DEBUG))
print(json.loads('"DEBUG"'))
print(LogLevel('DEBUG'))
will output
LogLevel.DEBUG
"DEBUG"
DEBUG
LogLevel.DEBUG
“Folie überspringen” is a much better way to do what I did with setting a yellow background color - easy to see and worst case scenario it’ll just get skipped
If you run tensorboard on a non-existing folder, you’ll get no feedback about it anywhere?.. No data on Tensorboard itself, nothing useful in CLI.
After some ill-fated undoing of commits, couldn’t find the work of an hour or so.

I already thought I had set up nvidia-smi and friends (Day 850 | Diensttagebuch (Work journal)), then didn’t use it for months, now when I tried it didn’t work anymore, nvidia-smi said “No devices found”
boltctl showed the device as connected and authorized, prime-select said nvidia was selected, modprobe showed that the correct drivers were used and dkms status had said the correct drivers were installed.

What worked:
Offtopic, when I was googling these issues I found my own serhii.net link above on the first page of Google for the key ’“nvidia-smi “no devices were found” authorized’, which is both nice and sad at the same time :)
EDIT: the next morning it didn’t work again. None of the same magic steps in all possible orders. I think it might be an issue with the eGPU or dock or something of that level. The best way to check this would be to do the nuclear option, uninstall all drivers, and install from the beginning, but I think my monthly quota of GPU stuff is full five times over now.
We’re on day 993 (!) of Diensttagebuch! Freaking awesome.
Was creating a requirements.txt for detectron2, official install instructions were:
python -m pip install detectron2 -f https://dl.fbaipublicfiles.com/detectron2/wheels/cu102/torch1.9/index.html
Answer specificalyl about this: python - How to format requirements.txt when package source is from specific websites? - Stack Overflow:
requirements.txt format is:
[[--option]...]
<requirement specifier> [; markers] [[--option]...]
<archive url/path>
[-e] <local project path>
[-e] <vcs project url>
<requirements specifier> is:
SomeProject
SomeProject == 1.3
SomeProject >=1.2,<2.0
SomeProject[foo, bar]
SomeProject~=1.4.2
The –option (such as the -f/–find-links) is the same as the pip install options you would use if you were doing pip install from the command line.
Therefore, in requirements.txt it ended up literally as this:
--find-links https://dl.fbaipublicfiles.com/detectron2/wheels/cu102/torch1.9/index.html detectron2
And by the way, detectron2’s own requirements.txt demonstrates nicely part of the above.

Best part about ag is that I don’t need to escape anything with its default settings:
pip freeze | ag "(detectron|torch)"
pip freeze | grep "\(detectron\|torch\)"
Suddenly stopped getting readable output.
Fix is to add the env variable JB_DISABLE_BUFFERING, without any value, to the env of the test.

The documentation about default confg covers all the parameters’ meanings and can be used as reference for that! detectron2.config — detectron2 0.5 documentation
And me dreaming up cfg.MODEL.CHECKPOINT_PERIOD is exactly what they wanted to avoid by disallowing the creation of new keys.

For the second time, discovered that Telegram Cache takes 40gb of disk space.
In the phone’s own menus related to disk space, this was shown as “Pictures” taking 40gb, not the Telegram app and its cache. But this info is exposed through Telegram’s own menus.
Who knew you could combine commands! This is how you start tracking tag1,tag2 starting from the end of the previous span:

TL;DR:
duc index ~/ --fs-exclude fuse.sshfs
duc is about disk space, before running it the index should be built/updated. Usually similar to duc index ~/.
If I have a sshfs mounted somewhere, the process never ends as it tries to index the folder where it’s mounted.
Found some solutions:
duc index ~/ --fs-exclude fuse.sshfs
ext3,ext4./etc/fstab didn’t have the sshfs filesystem, but mount called it fuse.sshfs and this worked!duc index ~/ -e "*somefilename*"
*folder\/file* etc).Bonus: -p shows progress during indexing.
Now I have a new alias in ~/.zshrc:
ducindex() {
duc index "$1" -p --fs-exclude fuse.sshfs
}
cdd CLI alias for CD-ing to directory containing a fileI copypaste a lot the locations of the files from pycharm/intellij to run them from CLI or something similar. Easiest way, because they are focused and I don’t need to focus on the files/project view for that. I can’t find an Action in pycharm/intellij to copypaste only the directory.
Yet another alias for today:
cdd() {
$(dirname "$1")
}
dirname gives the directory, dirname .. | cd and dirname ... | xargs cd don’t work (TODO - why?), so I’m using the zsh thing about “cd to the directory if it’s in a command by itself”.
Now cdd /home/me/wahtever/test.py takes me to /home/me/whatever/ which will saved tens of seconds per year!

I often do <CR>ddkkp or d$kp as a reverse-enter, moving what’s to the right of the cursor on the line above the current one. I’m sure something like this already exists in vim.
Detectron’s Yacs has a github repo with documentation and examples, much better than detectron’s own: rbgirshick/yacs: YACS – Yet Another Configuration System
This works:
comp_cfg.set_new_allowed(True)
comp_cfg['key'] = 'value'
Interesting bit about why it’s not like this by default:
We typically don’t use this so that typo in config file can be noticed. 2
Additionally, this is set per leaf, not per config - you can allow adding stuff to the root but not to its existing children.
And, still, even with comp_cfg.set_new_allowed(True), why can’t I merge_from_list etc. for non-existing keys? (TODO)
log.txt is nice and colorful on CLI, I don’t remember how to let vim interpret the CLI colors but less log.txt works magnificently.

If you are inside a screen, and need to write the entire contents to a file (not just the ones currently visible), this will work:
