In DEBIAN11, I write a code for serial display on GUI to plot a graph using dev/ttyACMO but unfortunately an error occurred that string could not convert to float here is the code:
import serial as sr
import matplotlib.pyplot asplt
import numpy as np
s=sr.Serial('/dev/ttyACM0',115200);
plt.close('all')
plt.figure();
plt.ion();
plot.show();
data = np.array([]);
i=0
while i<100
a=s.readline()
a.decode()
b = float(a[0:4])
data = np.append(data,b);
plt.plot(data);
plt.pause(0.01);
i=i+1
s.close()

When attemping to get the rdkit to work i keep getting an argument error i am unsure of how to solve.
mol_list1 = [Chem.MolFromSmiles(i) for i in tqdm(df_database['Ligand SMILES'], desc='Creating mol objects from database Smiles')]
mol_list2 = [Chem.MolFromSmiles(i) for i in tqdm(df_metabolites['Smiles'].dropna(), desc='And now for the metabolites!')]
mfp1 = [AllChem.GetMorganFingerprint(j, 4) for j in tqdm(mol_list1, desc='Getting fingerprints for database mols')]
ArgumentError: Python argument types in
rdkit.Chem.rdMolDescriptors.GetMorganFingerprint(NoneType, int) did
not match C++ signature: GetMorganFingerprint(class RDKit::ROMol mol,

I'm using Python's watchdog module to listen for created events on a certain directory. Where I do some processing on newly created .csv files. When I test my code with nothing in the handler the watchdog fires correctly for all pasted/created files, but when I add my code/logic inside the handler it fires less than expected (52/60 files for example).
OS used: Windows 10, code is expected to work on a Windows server.
Python version: 3.7.3
Code:
import time
from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler
import pandas as pd
import numpy as np
from error_handling import ErrorHandler
import os
from timeloop import Timeloop
from datetime import timedelta
import json
from fill_data import OnMyWatch2
class OnMyWatch:
# Set the directory on watch
watchDirectory = "."
def __init__(self):
self.observer1 = Observer()
def run(self):
self.observer1.schedule(Handler() , self.watchDirectory, recursive = True)
self.observer1.start()
try:
while True:
time.sleep(1)
except:
self.observer1.stop()
print("Observer Stopped")
self.observer1.join()
class Handler(FileSystemEventHandler):
#staticmethod
def on_any_event(event):
if event.is_directory:
return None
elif event.event_type == 'created':
try:
# Event is created, you can process it now
print("Watchdog received created event - % s." % event.src_path)
pathlower = str(event.src_path).lower()
if ".csv" in pathlower:
print("File is csv file")
# Once any code is added here the problem happens
# Example:
# df = pd.read_csv(event.src_path, names= ALL_INI.columnlistbundle.split("|"), sep="|", encoding='latin-1', engine='python')
# arraySelectedColumnsBundle = ALL_INI.selectedcolumnsbundle.split(",")
# bundle_df = df[np.array(arraySelectedColumnsBundle)]
else:
print("File is not csv file")
except Exception as e:
ErrorHandler(0, 'In Observer ', '-7', 'Exception ' + str(e), '', 1, '')

Have the python code with pytesseract & multiprocessing. When I start the code manually from PyCharm it works fine with any number of threads. When I start the code with Win Task Sheduler with 'threads=1' it works fine.
However if I start the code with Win Task Sheduler with 'threads=2' or more than 2, it finishes without processing the images and without any errors.
I've got log messages like this. Script starts but does nothing and there is no any errors in Win logs

Whats wrong? How can I fix this issue?
I'm using tkinter for my python3 GUI. The script I wrote, when executing in IDLE. But when I try to execute it without the GUI is not responding.
Here's the code:
#! python3
from tkinter import *
import tkinter as tk
class Program:
nameC = ""
master = ""
varC = ""
def callback(self):
self.nameC= filedialog.askopenfilename()
def __init__(self):
self.master = Tk()
self.varC = StringVar(self.master)
l1 = Label(text="Open file", relief=RIDGE,width=15)
l1.grid(row=0,column=0)
b1 = Button(text='Open', command=self.callback)
b1.grid(row=0,column=1)
program = Program()
mainloop()
So far I have a button and a label. If I click on the button, a filedialog is opened using the callback function
EDIT: fixed one error in the code
If it helps, I'm using windows
So after running the script in the console ( as mentioned not IDLE) I figured out that I would have to import filedialog:
#! python3
from tkinter import *
from tkinter import filedialog # this is what I needed
import tkinter as tk
class Program:
nameC = ""
master = ""
varC = ""
def callback(self):
self.nameC= filedialog.askopenfilename()
def __init__(self):
self.master = Tk()
self.varC = StringVar(self.master)
l1 = Label(text="Open file", relief=RIDGE,width=15)
l1.grid(row=0,column=0)
b1 = Button(text='Open', command=self.callback)
b1.grid(row=0,column=1)
program = Program()
mainloop()
STEPCAFControl which is available in python2.6 but webgl module is not available. So I am trying to run this below program .
from __future__ import print_function
import sys
from OCC.STEPCAFControl import STEPCAFControl_Reader
from OCC.STEPControl import STEPControl_Reader
from OCC.IFSelect import IFSelect_RetDone, IFSelect_ItemsByEntity
from OCC.Display.SimpleGui import init_display
#from OCC.Display.WebGl import threejs_renderer
step_reader = STEPControl_Reader()
status = step_reader.ReadFile('./models/screw.step')
if status == IFSelect_RetDone: # check status
failsonly = False
step_reader.PrintCheckLoad(failsonly, IFSelect_ItemsByEntity)
step_reader.PrintCheckTransfer(failsonly, IFSelect_ItemsByEntity)
ok = step_reader.TransferRoot(1)
_nbs = step_reader.NbShapes()
aResShape = step_reader.Shape(1)
print("Success")
else:
print("Error: can't read file.")
sys.exit(0)
display, start_display, add_menu, add_function_to_menu = init_display()
display.DisplayShape(aResShape, update=True)
start_display()
#my_renderer = threejs_renderer.ThreejsRenderer(background_color="#123345")
#my_renderer.DisplayShape(aResShape)
but getting this error.
How to solve this issue? Any suggestion?
