08/11/2021, 5:14 PMGreetings !
I'm facing a very similar issue to this one that happened in an older version
https://github.com/quantumblacklabs/kedro/issues/291
Basically I can't save my dataset due an encoding error

08/11/2021, 5:15 PMHi @User
have you tried this in your YAML entry?
Copy code
fs_args:
open_args_load:
mode: "rb"In general when this comes up this sort of approach tends to work
Copy code
yaml
my_dataset:
type: pandas.CSVDataSet
filepath: xxxxx.csv
fs_args:
open_args_load:
mode: "rb"
encoding: "utf-8"
open_args_save:
mode: "w"
encoding: "utf-8"b

08/11/2021, 5:17 PMHey there ! yes, that was my first attempt
d
datajoely
08/11/2021, 5:17 PMCould you post your stack trace
b
Bertozzo
08/11/2021, 5:17 PMi'll try this one

d
datajoely

datajoely
08/11/2021, 5:20 PMokay thats just a bad YAML file
there will be a bad indent somewhere
line 16 to be exact
b
Bertozzo
08/11/2021, 5:21 PMmm, thats interesting
and where do i find this file ?
i only know where my xlxs and csv are
d
datajoely
08/11/2021, 5:22 PMit's you catalog file
C:\Users\lbertozz\Downloads\aut-ia-avaliador-de-materias\conf\base\catalog.ymlline 16
b
Bertozzo
08/11/2021, 5:23 PMok, that was just an ident error 😅
now i am back to the original one, charmap encode etc etc
d
datajoely
08/11/2021, 5:24 PMokay interesting
Can you post your YAML entry here?
for that dataset
b
Bertozzo
08/11/2021, 5:25 PMone moment, i guess i found it
d
datajoely
08/11/2021, 5:25 PMno problem
b
Bertozzo
08/11/2021, 5:25 PMi need to put this in all csvs right ?
so i can read them all correctly
d
datajoely
08/11/2021, 5:26 PMThere is a way to re-use the same pattern over and over
but let's get it working for one
Copy code
yaml
my_dataset:
type: pandas.CSVDataSet
filepath: xxxxx.csv
load_args:
on_bad_lines: skip
encoding: 'utf-8'the other option is to try different encodings like
utf-8-sigutf-16b
Bertozzo
08/11/2021, 5:28 PMi did the same command to all df, an looks like it advanced, but now its saying that saving none to a dataset is not allowed
which is pretty logical tbh
d
datajoely
08/11/2021, 5:29 PMwhich command are you talking about?
b
Bertozzo
08/11/2021, 5:29 PMthis one
d
datajoely
08/11/2021, 5:29 PMYou will get the
Nonenodeah understood
So I'm a little confused, did we get it working?
or do you still need help
b
Bertozzo
08/11/2021, 5:31 PMFile "c:\users\lbertozz\appdata\local\programs\python\python37\lib\site-packages\kedro\io\core.py", line 232, in save
raise DataSetError("Saving
NoneDataSetNoneDataSetthats was the last message
d
datajoely
08/11/2021, 5:31 PMOkay so can you show me the
Nodebecause it works by
Catalog ->
load()Node(Python function)save()If you're getting the
Nonenot a DataFrame
b
Bertozzo
08/11/2021, 5:33 PMwhats the most weird of all
is that all my colleagues that use ubuntu can run it
without any issues
d
datajoely
08/11/2021, 5:34 PMhmm
b
Bertozzo
08/11/2021, 5:34 PMthey dont even need to put the encoding parameters
d
datajoely
08/11/2021, 5:34 PMmaybe its your Python environment
are you running in a virtual env?
b
Bertozzo
08/11/2021, 5:34 PMnope
d
datajoely
08/11/2021, 5:35 PMso I can't guarantee that will fix things
but it sometimes makes things easier not having to worry about multiple Python versions, multiple version of Kedro etc
b
Bertozzo
08/11/2021, 5:35 PMthats what i've done, just installed the 37, set as a global variable on my system
and then as a prymary interpreter on vscode
d
datajoely
08/11/2021, 5:36 PMAnd we're sure it's the same version of the code?
this is super weird
Can you post a screenshot of the catalog entry and the python node
I can't really work it out without seeing them
b
Bertozzo
08/11/2021, 5:37 PMone moment pls
can i call u pls ? and then share the screen ?
d
datajoely
08/11/2021, 5:41 PMI can't tonight (I'm also on calls 🤦♂️)
I could book some time tomorrow?
or do it async on here
b
Bertozzo
08/11/2021, 5:42 PMnp
ok, lets start over
d
datajoely
08/11/2021, 5:43 PMWould you like to book some time in tomorrow?
as it's getting towards end of day here in London
b
Bertozzo
08/11/2021, 5:44 PMthats my screen rn
d
datajoely
08/11/2021, 5:44 PMokay and I need to see the
.pyif you scroll a bit further up on the terminal it should tell you the name of the node
b
Bertozzo
08/11/2021, 5:46 PMlike this ?
021-08-11 14:43:12,636 - kedro.runner.sequential_runner - WARNING - There are 2 nodes that have not run.
You can resume the pipeline run by adding the following argument to your previous command:

d
datajoely
08/11/2021, 5:46 PMEven further please
you can right click the terminal and select all -> copy
That's very helpful thank you
so let me explain how to look at the logs as it explains whats going on
The node you need to look at is called
full_data_cleanand that will be in a
.pyIt looks like there is a bad return somewhere in there where a
Nonesorry my screenshot is run
the node to look at is this one
download_filesb
Bertozzo
08/11/2021, 5:55 PMok, im checking for it
d
datajoely
08/11/2021, 5:55 PMSo this is no longer a CSV encoding issue
it looks like the encoding tweak fixed things
but now is just a badly formed node
I'm going to log off for the evening - but feel free to post questions here and I'll pick them up when I'm next online 🙂
good luck!

Bertozzo
08/11/2021, 5:57 PMi see, and why do you think its not working then ?
