hi i am trying to add new blocks in gnuradio . I tried to follow the the procedure mentioned in gnuradio website
http://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModules?version=24
but when in terminal window i write "gr_modtool newmod howto"
it gives following error
File "/usr/local/bin/gr_modtool", line 41, in <module>
main()
File "/usr/local/bin/gr_modtool", line 36, in main
modtool.setup()
File "/usr/local/lib/python2.7/dist-packages/gnuradio/modtool/modtool_newmod.py", line 70, in setup
self._srcdir = gr.prefs().get_string('modtool', 'newmod_path', options.srcdir)
File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/gnuradio_core_general.py", line 18953, in get_string
return _gnuradio_core_general.gr_prefs_get_string(self, *args, **kwargs)
TypeError: in method 'gr_prefs_get_string', argument 4 of type 'std::string const'
please tell me how to fix it.
To create your own modules in GNU Radio Companion using the gr_modtool try this:
$ gr_modtool newmod
Name of the new module: myPlugin
To add processing blocks to your newly created module use:
../gr-myPlugin$ gr_modtool add
You can choose if you want a cpp or python block by adding the "-l" specificier:
../gr-myPlugin$ gr_modtool add -l python

I am trying to run a model using keras's fit_generator with a tensorboard_callback for profiling a specific epoch. I am running the following code for the generator:
def gen(source):
loopable = iter(source)
for batch in loopable:
yield (batch[0], batch[1])
In the main training script I am instantiating the generator and using the model with a tensorboard callback as follows:
train_gen = gen(train_datasource)
log_dir="logs/profile/" + datetime.datetime.now().strftime("%Y%m%d-%H%M%S")
tensorboard_callback = tf.keras.callbacks.TensorBoard(log_dir=log_dir, histogram_freq=1, profile_batch = 3)
m.fit_generator(train_gen, epochs=5, steps_per_epoch=500, use_multiprocessing=True, workers=32, callbacks=[tensorboard_callback])
The main issue I am facing is that the training always halts with the error 'Function' has no attribute 'fetch_callbacks' with the following stack trace:
m.fit_generator(train_gen, epochs=5, steps_per_epoch=500, use_multiprocessing=True, workers=32, callbacks=[tensorboard_callback])

self.merged] = self._fetch_callback
AttributeError: 'Function' object has no attribute 'fetch_callbacks'
I am using tensorflow 1.15 also tried downgrading to 1.14 but still no success. I am trying to train with the tensorboard callback to debug the performance for a specific epoch other than the first one. But so far my attempts have failed to make the callback function correctly. I made sure the GPU is running and detected correctly too.
Any help would be much appreciated.
I ended up using tf.keras fit function instead of fit generator and it worked correctly as expected:
m.fit(x=train_gen, epochs=5, steps_per_epoch=500, use_multiprocessing=True, workers=8, callbacks=[tensorboard_callback])
I'm trying to create a .exe file from a python script (which use PyQt4 GUI and matplotlib). I'm using cx_Freeze version 5.1.1 for 64-bit windows with the following setup.py:
import cx_Freeze
import sys
import matplotlib
base = "Win32GUI"
includes = ["atexit"]
buildOptions = dict(
#create_shared_zip=False,
#append_script_to_exe=True,
includes=includes
)
executables = [cx_Freeze.Executable(script = "main.py", base = base)] # icon = "chart32.jpg")]
cx_Freeze.setup(
name= "1ChPlotGUI",
options = dict(build_exe=buildOptions), # {"build_exe": {"packages": ["matplotlib"], "include_files":["chart32.jpg"]}},
version = "0.01",
description = "1 Channel Plotting app with GUI",
executables = executables
)
after running
python setup.py build
in the cmd from the position of
C:\Users\Us.Er\Pyth-examples\Qt\UI-examples\ChannelplotGUI-to-exe
I have something like this:

h = BeginUpdateResource(pathname, 0)
pywintypes.error: (2, 'BeginUpdateResource', 'The system cannot find the file specified.')
What is the possible solution for above problem?
EDIT
To be clear: I don't want to add any icon for now. I am happy with just a simple, working .exe
I have added the target in this way:
executables = [cx_Freeze.Executable(script = "main.py", base = base, targetName="main.exe")]
I have tried to add
targetDir = "C:\Users\Us.Er\Pyth-examples\Qt\UI-examples\ChannelplotGUI-to-exe"
anyway, the return is:
TypeError: __init__() got an unexpected keyword argument 'targetDir'
The main problem is as before - the error with last lines as:
h = BeginUpdateResource(pathname, 0)
pywintypes.error: (2, 'BeginUpdateResource', 'The system cannot find the file specified.')
In my case the issue was solved by changing
'build_exe': 'build_folder'
to
'build_exe': './/build_folder'
This is because open(pathname) would work on the pathname='build_folder\\executable.exe', allowing the code to advance during the check at the begginning of the stamp method, but BeginUpdateResource(pathname, 0) would only work on './/build_folder\\executable.exe'
Solution
options = {
'build_exe': {
'build_exe': './/build'
}
}
Note: .//build here, build is the folder name where you want to build your project.
Thanks to help of user jpeg I managed to successfully freeze the script.
To eliminate the problem with path I have added a line print(pathname) in win32verstamp.py before line 159.
The print statement worked fine showing the relative path to the newly made .exe file.
Despite showing the correct path, the error was still present. I went to the stamp() definition in win32verstamp.py and found a try - except block, and have inserted print(pathname) over there.
The part is:
def stamp(pathname, options):
# For some reason, the API functions report success if the file is open
# but doesnt work! Try and open the file for writing, just to see if it is
# likely the stamp will work!
#print("Current path is " + pathname)
try:
f = open(pathname, "a+b")
f.close()
print("Possible to open" + pathname) #<---line added
except IOError, why:
print "WARNING: File %s could not be opened - %s" % (pathname, why)r code here
....
Since that the freeze was possible. (Not sure why tho, I'm happy to add some info if explanation is known)
I had the same issue tying to freeze my PyQt5 app (using python 3.7 under windows 10) with the following message :
h = BeginUpdateResource(pathname, 0)
pywintypes.error: (2, 'BeginUpdateResource', 'Le fichier spécifié est introuvable.')
So I choose to use cx_freeze Sample provided as a first step.
(This samples are availables after cx_freeze installation under MyVENVpath\Lib\site-packages\cx_Freeze\samples)
The very basic PyQt5 exemple was working, but my case was way more complex as I used several sub Python class I have developed.
I honestly don't really understand why but I was able to make it work So here is all modifications I have performed :
In setup.py identify sub python files
add my personnal packages and class like this :
include = ["PyQt5", "PySerial", "myclass1", "myclass2", "myclass3", "PandasModel"]
packages = ["PySerial", "myclass1", "myclass2", "myclass3", "PandasModel", "pandas","math"]
Use relative path in setup.py
executables = [cx_Freeze.Executable(os.getcwd() + r'\..\..\MyFileName.py', base=base)]
include_files = [(os.getcwd() + r'\..\..\CalibrationTool.ui', r'Inputs\GUI\CalibrationTool.ui')
The reason for "...." is to jump two directories higher level, as my python.exe is in sub folders VENV\Script\
Add python Files containing "Myclass1" at same level as setup.py.
Even if in my application, class files are in a subfolder Input\Packages\Myclass1File.py, I had to copy-paste it at the same level as setup.py. This way the include and package line of setup.py work and was able to generate the executable.
Last but not least,the terminal command
I have no idea why but the only command who did suceed was:
to use full path to the python.exe and full path to the setup.py with the "build" at the end.
cmd:>C:\Folder1\Folder2\MyVENV\Scripts\python.exe D:\Folder1\Folder2\setup.py build
This finaly created the executable in a build folder under C:\Folder1\Folder2\MyVENV\Scripts\
I copied the codes from the example to learn scapy. But realized the IDE showed the error with unsolved reference for IP() & TCP(). Anyone know how to fix this?
Here are the codes:
#! /usr/bin/env python
from scapy.all import *
import logging
logging.getLogger("scapy.runtime").setLevel(logging.ERROR)
dst_ip = "10.0.0.1"
src_port = RandShort()
dst_port=80
tcp_connect_scan_resp = sr1(IP(dst=dst_ip)/TCP(sport=src_port,dport=dst_port,flags="S"), timeout=10)
if(str(type(tcp_connect_scan_resp))==""):
print("Closed")
elif(tcp_connect_scan_resp.haslayer(TCP)):
if(tcp_connect_scan_resp.getlayer(TCP).flags == 0x12):
send_rst =sr(IP(dst=dst_ip)/TCP(sport=src_port,dport=dst_port,flags="AR"),timeout=10)
print("Open")
elif (tcp_connect_scan_resp.getlayer(TCP).flags ==0x14):
print("Closed")
I'm using Pycharm IDE. Python2.7 and scapy 2.4.0. I searched on stackoverflow and found someone asked the same question before but no answer.....
Here is the error after I tried to run the codes:

I answered the same Unsolved Reference issue last week here:
vscode import error: from scapy.all import IP
In short, don't worry about that error, it's a limitation of Pylint (or similar). I propose a workaround in the other question, if you'd like to remove the error/warning.
For the No /dev/bpf handle is available error, have you tried running the script as root? I see that suggested as a solution over on this GitHub issue: https://github.com/secdev/scapy/issues/1343
I have an app running online under web2py. Now, i am adding names.yml file which i need to call in my controller file (default.py) on web2py server. where should I keep the .yml/.yaml files. Currently I have kept them in views with default/names.yml but when I call it in default.py like:
dicttagger = DictionaryTagger([ 'default/names.yml', 'default/surname.yml'])
i get no such file error.
Also tried below:
dicttagger = DictionaryTagger([ 'views/default/names.yml', 'views/default/surname.yml'])
same error
class snapshot as under:
class DictionaryTagger(object):
def __init__(self, dictionary_paths):
files = [open(path, 'r') for path in dictionary_paths]
dictionaries = [yaml.load(dict_file) for dict_file in files]
map(lambda x: x.close(), files)
Any suggestions as how to do this or am I making mistake of using yaml/yml file in we2py and it doesn't work in web2py app hosted online?
question 2
thank you. it resolved an error but I am not sure how to add nltk.download() into my hosted app. I keep getting the below error. Can you pls have a look:

You can store the files wherever you want, but if you're using the Python open function, you'll need to give it full paths, not paths relative to the web2py application folder. Instead, try:
import os
dicttagger = DictionaryTagger([os.path.join(request.folder, 'views',
'default', 'names.yml'),
...])
I have been struggling with this for a while. I have used py2exe and cx_freeze to package everything. I am using a 32 bit machine and Everything works fine and the interface opens up and everything just that I know the entire puLP package is not being copied correctly into the package. I know this because the solver does not work. Inside both library zips in the packages created by py2exe and cx_freeze, there are only .pyc files included where PuLP has cbc.exe and other file types that make the solver work.
Is there any work around this? I have tried copying the actual PuLP package into the library.zip as well as into the dist folder and that didn't work.
Here is the setup I used for py2exe:
import sys
from cx_Freeze import setup, Executable
# Dependencies are automatically detected, but it might need fine tuning.
build_exe_options = {"packages": ["pulp"],
"icon": "icon.ico",
"include_files": ["icon.ico","cbc.exe","cbc-32","cbc-64","cbc-osx-64","CoinMP.dll"]}
# GUI applications require a different base on Windows (the default is for a
# console application).
base = None
if sys.platform == "win32":
base = "Win32GUI"
setup( name = "my_app",
version = "0.1",
options = {"build_exe": build_exe_options},
executables = [Executable("my_app.py", base=base)])
I received the following error:
Exception in Tkinter callback
Traceback (most recent call last):
File "Tkinter.pyc", line 1470, in __call__

File "my_app.py", line 467, in branchAndBound
File "pulp\pulp.pyc", line 1619, in solve
AttributeError: 'NoneType' object has no attribute 'actualSolve'
EDIT
I tried to change the paths to cbc.exe and CoinMP.dll but that didn't really work either. I am probably missing something.
I changed the following inside solvers.py in the PuLP package:
try:
coinMP_path = config.get("locations", "CoinMPPath").split(', ')
except configparser.Error:
coinMP_path = ['/Users/al/Desktop/my_app/build/exe.win32-2.7']
try:
cbc_path = config.get("locations", "CbcPath")
except configparser.Error:
cbc_path = '/Users/al/Desktop/my_app/build/exe.win32-2.7'
try:
pulp_cbc_path = config.get("locations", "PulpCbcPath")
except configparser.Error:
pulp_cbc_path = '/Users/al/Desktop/my_app/build/exe.win32-2.7'
What am I missing or doing wrong?
