PyCodeStyle is installed and I defined the file as shown here. Now I would like to add comments:
max-line-length = 166
# individual setting
The comment in an separate line starting with # works. My preferered method to have it in the same line does not:
max-line-length = 166 # individual setting
Any other method unlike # to get this work?

This doesn't look like a PowerShell issue; the python interpreter looks like it is being run correctly. I suggest adding the python tag to your question to get the right people involved.
Having located the source, it seems as if some of the text files in the following directory aren't in the format expected by convert_annotations.py:
C:\OIDv4_ToolKit\OID\Dataset\train\Vehicle registration plate\Label\
You can verify this with:
print("labels length =", len(labels))
after the line.split() method. If you get a length of 1, it is likely the items on a line somewhere aren't separated with whitespace, for example with commas. You can also inspect the files manually to determine the format. To find them, you can use:
print(os.path.join(os.getcwd(), filename))
inside the the for loop, which is on Line 54 in the source I linked above. Note also that the string split() method supports a custom separator as the first argument, should the files be in a different format.
This issue occurs when you don't put the class name in classes.txt
The class name should be same in classes.txt as downloaded class.
Question about running a custom function in Powershell.
I'm on Windows 10 and I'd like to somehow print my monorepository's directory tree structure excluding node_modules. This is not supported out of the box but requires a custom function to be defined. I found one solution on StackOverflow (https://stackoverflow.com/a/43810460/9654273), which would enable using a command like:
tree -Exclude node_modules -Ascii > tree.txt
The problem is I don't know what to do with the provided source code :D The answer says "add to your $PROFILE, for instance", so I ran notepad $PROFILE in PowerShell, pasted the code snippet there, saved it and tried running the command. It didn't work because I did something wrong. According to the StackOverflow post's comments from anand_v.singh and mklement0 I was still running some other tree command, not the one I just attempted to define.
So how do I use a custom function in PowerShell? Starting point is that source code is on StackOverflow and I don't know where to paste it. Or do you know some other, easier way to print a directory tree on Windows 10 excluding node_modules?
I had the same problem with that function. The issue is the special characters in the hashtable at line 106:
$chars = #{
interior = ('├', '+')[$ndx]
last = ('└', '\')[$ndx] #'
hline = ('─', '-')[$ndx]
vline = ('│', '|')[$ndx]
space = ' '
}
I changed the special characters to ascii as follows:
$chars = #{
interior = ('+', '+')[$ndx]
last = ('\', '\')[$ndx] #'
hline = ('-', '-')[$ndx]
vline = ('|', '|')[$ndx]
space = ' '
}
The only downside is that you do not now have the option of using special graphics characters (the Ascii switch is still there, but does nothing). Maybe someone could tell us how to embed them properly.
I just notices that the command line tool, called like this: "ruamel.yaml.cmd rt --save $YAML_FILE", will break lists that either contain long strings, or hashes:
Example list containing a hash:
Source:
telegraf::inputs:
cpu:
- percpu: true
totalcpu: true
report_active: true
output:
telegraf::inputs:
cpu:
- percpu: true
totalcpu: true
report_active: true
example list containing long string:
source:
rsyslog::config::snippets:
00_forward:
ensure: 'present'
lines:
- 'if $syslogfacility != 1 then {'
- 'action(Name="collector-syslog" Type="omfwd" Target="%{hiera("rsyslog_server")}" Port="514" Action.ResumeInterval="5" Protocol="tcp")'
- '}'
output:
rsyslog::config::snippets:
00_forward:
ensure: present
lines:
- if $syslogfacility != 1 then {
- action(Name="collector-syslog" Type="omfwd" Target="%{hiera("rsyslog_server")}"
Port="514" Action.ResumeInterval="5" Protocol="tcp")
- '}'
I already created a bug report for this, but it was deleted with a comment pointing to https://yaml.readthedocs.io/en/latest/example.html?highlight=indent#output-of-dump-as-a-string.
But I am not sure how this code snipped should help me with the command line tool.
Or is the tool deprecated, and I have to roll my own?
The automatic detection of the indent seems incorrect for your input, as that input is inconsistent (your mappings are indented 2 positions and your sequences 4 positions with an offset for the block sequence indicator of 2). ruamel.yaml.cmd as on PyPI doesn't support different indentation levels for sequences and mappings (ruamel.yaml didn't when that was written, it does now).
Apart from that you cannot set the line width for the output in ruamel.yaml.cmd for older versions ( before 2020-12-01), and those versions are using the default 80 characters for the wrapping.
I recommend you upgrade to 0.5.6 and use the command line options:
yaml rt --indent 2 --width 1024 --save <yourfile>
The appropriate repository for ruamel.yaml.cmd is https://sourceforge.net/p/ruamel-yaml-cmd/code/ci/default/tree/ . A bug report on ruamel.yaml which can only be used from a Python program, should include the minimal source code of the program that reproduces the error, and if not provided, issues will be removed as announced on its create issue page.
Say I have a file with 100 lines of code in a file. 1-90 is a python class code. 91-100 is some code that uses the class.
line 1 - class Test:
line 90 - end of class Test
line 91 - t = Test()
line 92 - input = [1,2,3,4,5]
line 93 - output = t.run(input)
line 94 - print(output)
Now I do changes in the following order
change line 92 ( this breaks the code )
fix something in the class from line 1 - line 90. The new input works
To verify the prev input, I need to undo just the line 92. But an undo will undo all the fixes in the file as well.
So I was wondering if there is a way to do it? Or is it asking for too much? As it would have to keep track of all the lines. But if the undo history has a line number already saved in it, I guess this would not be that hard to do.
I have a binary file that I need to process, but it contains no line breaks in it.
The data is arranged, within the file, into 104 character blocks and then divided into its various fields by character count alone (no delimiting characters).
I'd like to firstly process the file, so that there is a line break (`n) every 104 characters, but after much web searching and a lot of disappointment, I've found nothing useful yet. (Unless I ditch PowerShell and use awk.)
Is there a Split option that understands character counts?
Not only would it allow me to create the file with nice easy to read lines of 104 chars, but it would also allow me to then split these lines into their component fields.
Can anyone help please, without *nix options?
Cheers :)
$s = get-content YourFileName | Out-String
$a = $s.ToCharArray()
$a[0..103] # will return an array of first 104 chars
You can get your string back the following way, the replace removes space char( which is what array element separators turn into)
$ns = ([string]$a[0..103]).replace(" ","")
Using the V4 Where method with Split option:
$text = 'abcdefghi'
While ($text)
{
$x,$text = ([char[]]$text).where({$_},'Split',3)
$x -join ''
}
abc
def
ghi
