Obviously, this isn't Ada code, but crashing GPS doesn't seem reasonable.

I'm executing the Dagster tutorial, and I got stuck at the Multiple and Conditional Outputs step.
In the solid definitions, it asks to declare (among other things):
output_defs=[
OutputDefinition(
name="hot_cereals", dagster_type=DataFrame, is_required=False
),
OutputDefinition(
name="cold_cereals", dagster_type=DataFrame, is_required=False
),
],
But there's no information where the DataFrame cames from.
Firstly I have tried with pandas.DataFrame but I faced the error: {dagster_type} is not a valid dagster type. It happens when I try to submit it via $ dagit -f multiple_outputs.py.
Then I installed the dagster_pyspark and gave a try with the dagster_pyspark.DataFrame. This time I managed to summit the DAG to the UI. However, when I run it from the UI, I got the following error:
dagster.core.errors.DagsterTypeCheckDidNotPass: Type check failed for step output hot_cereals of type PySparkDataFrame.

Does anyone know how to fix it? Thanks for the help!
As Arthur pointed out, the full tutorial code is available on Dagster's github.
However, you do not need dagster_pandas, rather, the key lines missing from your code are:
if typing.TYPE_CHECKING:
DataFrame = list
else:
DataFrame = PythonObjectDagsterType(list, name="DataFrame") # type: Any
The reason for the above structure is to achieve MyPy compliance, see the Types & Expectations section of the tutorial.
See also the documentation on Dagster types.
I was stuck here, too, but luckily I found the updated source code.
They have updated the docs so that the OutputDefinition is defined beforehand.
Update your code before sorting and pipeline like below:
import csv
import os
from dagster import (
Bool,
Field,
Output,
OutputDefinition,
execute_pipeline,
pipeline,
solid,
)
#solid
def read_csv(context, csv_path):
lines = []
csv_path = os.path.join(os.path.dirname(__file__), csv_path)
with open(csv_path, "r") as fd:
for row in csv.DictReader(fd):
row["calories"] = int(row["calories"])
lines.append(row)
context.log.info("Read {n_lines} lines".format(n_lines=len(lines)))
return lines
#solid(
config_schema={
"process_hot": Field(Bool, is_required=False, default_value=True),
"process_cold": Field(Bool, is_required=False, default_value=True),
},
output_defs=[
OutputDefinition(name="hot_cereals", is_required=False),
OutputDefinition(name="cold_cereals", is_required=False),
],
)
def split_cereals(context, cereals):
if context.solid_config["process_hot"]:
hot_cereals = [cereal for cereal in cereals if cereal["type"] == "H"]
yield Output(hot_cereals, "hot_cereals")
if context.solid_config["process_cold"]:
cold_cereals = [cereal for cereal in cereals if cereal["type"] == "C"]
yield Output(cold_cereals, "cold_cereals")
You can also find the whole lines of codes from here.
Try first to install the dagster pandas integration:
pip install dagster_pandas
Then do:
from dagster_pandas import DataFrame
You can find the code from the tutorial here.
I'm trying to read serial data from an Arduino to my Mac (10.12.6). I have downloaded the Synapse library for FreePascal (Lazarus v.2.0.8) from here but I run into an error...
The Arduino is programmed using the Arduino IDE and sends random numbers (between 0 and 255) as a string to the serial port. I am trying to read these strings using FreePascal so that I can plot the values.
Following instructions here I have downloaded and used the Synapse library in the following way:
1) Uncompress the library folder
2) In Lazarus goto 'Project' -> 'Project Inspector' -> 'Add Files from File System' -> select 'synaser.pas'.
3) Add the following code to the form button event:
procedure TForm1.Button1Click(Sender: TObject);
var
ser: TBlockSerial;
begin
ser := TBlockSerial.Create;
try
ser.Connect('my-com-port'); // write here Arduino COM port number (on linux it's something like '/dev/ttyUSB0')
Sleep(250);
ser.config(9600, 8, 'N', SB1, False, False);
ser.SendString('on'); // button 2 should have 'off' here
finally
ser.free;
end;
end;
4) Press run.
An error message appears in the synaser.pas file:
Error incompatible types: got "ShortInt" expected "Pointer"..
Here's the part of the synaser.pas file referred to:
{$IFNDEF MSWINDOWS}
procedure TBlockSerial.Purge;
begin
{$IFNDEF FPC}
SerialCheck(ioctl(FHandle, TCFLSH, TCIOFLUSH));
{$ELSE}
{$IFDEF DARWIN}
SerialCheck(fpioctl(FHandle, TCIOflush, TCIOFLUSH)); { <------ here*******}
{$ELSE}
SerialCheck(fpioctl(FHandle, TCFLSH, Pointer(PtrInt(TCIOFLUSH))));
{$ENDIF}
{$ENDIF}
FBuffer := '';
ExceptCheck;
end;
I am using a Mac and this error seems to be related to a windows system?
Thanks #tonypdmtr.
I had to change the 'synaser.pas' file in the following way to get it to work. Bit of a hack I feel:
Change line 1939 to the following:
SerialCheck(fpioctl(FHandle, TCIOflush, Pointer(PtrInt(TCIOFLUSH))));
Comment out lines 2201, 2202 and 2204 in the same. This sounds like a bad way of doing it but I got it to work.
Changing the button event to the following code allows me to read a single line of data from the Arduino with each button click:
procedure TForm1.Button1Click(Sender: TObject);
var
ser: TBlockSerial;
begin
ser := TBlockSerial.Create;
try
ser.Connect('/dev/cu.wchusbserial1420'); // write here Arduino COM port number (on linux it's something like '/dev/ttyUSB0')
Sleep(250);
ser.config(9600, 8, 'N', SB1, False, False);
Label1.Caption := ser.RecvString(100);
finally
ser.free;
end;
end;
I feel the library should just work without having to change it.
CLIPS version: 6.31 .
language: c++ clips C API .
I get a coredump file when execute ProfileInfoCommand after EnvRun.
Why is this error happening? Is there any usage error here? Or this is a bug?
The c++ code 1:
#define PROFILING_FUNCTIONS 1
// ...
EnvReset(clips);
// ...
EnvLoadFactsFromString(clips, facts.str().c_str(), -1);
// ...
EnvRun(clips, 100000);
ProfileInfoCommand(clips);
I know if PROFILING_FUNCTIONS is defined as 1, the EnvRun function will start profile automatically.So I use ProfileInfoCommand after EnvRun,but the coredump has occurred!
And I also tried using another method,but the process also generated a core dump(the same backtrace like the c++ code 1).
The c++ code 2:
EnvReset(clips);
Profile(clips, "constructs");
// ...
EnvLoadFactsFromString(clips, facts.str().c_str(), -1);
// ...
EnvRun(clips, max_iters);
Profile(clips, "off");
ProfileInfoCommand(clips);
The coredump file is following:

Setting PROFILING_FUNCTIONS to 1 does not automatically profile code when EnvRun is called. It determines whether the profiling functions are included in the CLIPS executable. See Section 2.2 of the Advanced Programming Guide. The functions available for profiling from the CLIPS command are documented in Section 13.15, Profiling Commands, of the Basic Programming Guide. The ProfileInfoCommand can't be called directly. If you want to call a CLIPS command/function that isn't part of the API described in the Advanced Programming Guide, use the EnvEval API:
DATA_OBJECT returnValue;
EnvEval(theEnv,"(profile-info)",&returnValue);
I have used the following code to have a graph in main page of doxygen

But I get the following message "reached end of file while inside a dot block! The command that should end the block seems to be missing!"
Can anyone help?
Thanks.
The solution is like the message says:
warning: reached end of file while inside a dot block! The command
that should end the block seems to be missing!
it is the mistake that is easily overlooked, written is
\endot this should be \enddot (note the double d)
I'm trying to follow this OpenFOAM tutorial for using Gmsh to generate Axisymmetric mesh. The files are provided here. However when I try to solve the problem using the pimpleFoam solver I get the error:
--> FOAM FATAL ERROR:
Unknown TurbulenceModel type RASModel

As explained in this page apparently the syntax of turbulenceProperties in case/constant has changed. So I edited the turbulenceProperties file from:
simulationType RASModel;
to
simulationType RAS;
RAS
{
RASModel kEpsilon;
turbulence on;
printCoeffs on;
}
but then I get a different error:
FOAM FATAL IO ERROR:

It seems like the tutorial is meant for an older version of OpenFOAM. I would appreciate if you could help me know what is the problem and how I can solve it.
The goal for me is to learn how to make axisymmetric mesh using Gmsh. so out of the box solutions or tutorials for the newer versions of OpenFOAM als would do.
P.S. I have reported the issue here in the Github repo
I was able to solve the issue by looking into the different versions of axisymmetricJet template provided in official OpenFOAM GitHub repo (version 2.3.x and version 5.x). Changes to be made:
in case/constant/RASProperties add these at the end:
kEpsilonCoeffs
{
Cmu 0.09;
C1 1.44;
C2 1.92;
sigmaEps 1.3;
}
in case/constant/turbulenceProperties replace the line simulationType RASModel; with:
simulationType RAS;
RAS
{
RASModel kEpsilon;
turbulence on;
printCoeffs on;
}
in case/system/fvSchemes change the line div((nuEff*dev(T(grad(U))))) Gauss linear; to div((nuEff*dev2(T(grad(U))))) Gauss linear;
It the solver converges as expected. I still don't know what these changes mean and how they work. I will add them as soon as I figure that out. I have forked the GitHub repo here including the required edits.
