When I run the code, it doesn't give an error and doesn't say anything. I checked the speaker and everything is fine
Here my code:
import pttsx3
speak = 'Hello world'
saying = pyttsx3.init()
saying.say(speak)
saying.runAndWait()
import pttsx3 <--- Missing y in the library, working properly after add it
import pyttsx3

When I write
import "#openzeppelin/contracts/token/ERC20/ERC20.sol";
contract DaiTokenMock is ERC20{
The code compiles perfectly fine. However, I'm trying to import ERC20Mintable, in which case I get the error "ParserError: Source "#openzeppelin/contracts/token/ERC20/ERC20Mintable.sol" not found"
Any help fixing this would be greatly appreciated!
When my Flask+PySpark application has a function with #udf or #pandas_udf annotation, it will not start. If I simply remove the annotation, it does start.
If I try to start my application with Flask, the first pass of lexical interpretation of the script is executed. For example, the debugger stops at import lines such as
from pyspark.sql.functions import pandas_udf, udf, PandasUDFType
. However no statement is executed at all, including the initial app = Flask(name) statement. (Could it be some kind of hidden exception? )
If I start my application without Flask, with the same exact function and with the same imports, it does work.
These are the imports:
from pyspark.sql import SQLContext
from pyspark.sql import SparkSession
from pyspark.sql.functions import pandas_udf, udf, PandasUDFType
import pandas as pd
This is the function:
#pandas_udf('string', PandasUDFType.SCALAR)
def pandas_not_null(s):
return s.fillna("_NO_NA_").replace('', '_NO_E_')
This is the statement that is not executed iff #pandas_udf is there:
app = Flask(__name__)
This is how IntelliJ starts Flask:
FLASK_APP = app
FLASK_ENV = development
FLASK_DEBUG = 1
In folder /Users/vivaomengao/projects/dive-platform/cat-intel/divecatintel

I'm running MacOS in my own computer.
I found the problem. The problem was that the #pandas_udf annotation required a Spark session at the time that the module is loaded (some kind of "first pass parsing" in Python). To solve the problem, I first called my code that creates a Spark session. Then I imported the module that has the function with the #pandas_udf annotation after. I imported it right inside the caller function and not at the header.
To troubleshoot, I set a breakpoint over the #pandas_udf function (in PyCharm) and stepped into the functions. With that I could inspect the local variables. One of the variables referred to something like "sc" or "_jvm". I knew from a past problem that that happened if the Spark session was not initialized.
RN version: 0.50
Testing on Android, haven't tested on iOS
I am trying to use ErrorUtils.setGlobalHandler as described in this github issue: https://github.com/facebook/react-native/issues/1194
However, what is not clear from the issue is how to import ErrorUtils. It's not in the react documentation: https://facebook.github.io/react-native/docs/0.50/getting-started.html
Previously, in RN 0.41, I was able to import ErrorUtils with import ErrorUtils from "ErrorUtils"; However, in 0.50 I am getting a red react popup with the following message when I try to import ErrorUtils like this:
com.facebook.react.common.JavascriptException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'http://localhost:8081/index.bundle?platform=android&dev=true&minify=false' failed to load.
I've also tried import { ErrorUtils } from 'react-native'; but it doesn't seem to exist there. The error is:
Cannot read property 'setGlobalHandler' of undefined
How do I properly import ErrorUtils in RN 0.50?
ErrorUtils is a global variable, therfore it doesn't need to be imported. You can verify this with console.log(global.ErrorUtils)
However it is exported as module anyways (here). The comment there also has more information why it is done this way.
You can import the module like this:
import ErrorUtils from 'ErrorUtils';
For anyone on RN61+, you should no longer import the module as you will experience the following error in the running metro bundler:
Error: Unable to resolve module `ErrorUtils`
Instead, just use the module without importing as this is a global variable, as stated by leo
I did created a global.d.ts to define a global variable,
interface Global {
ErrorUtils: {
setGlobalHandler: any
reportFatalError: any
getGlobalHandler: any
}
}
declare var global: Global
then, at where you are trying to use it, simply
global.ErrorUtils.setGlobalHandler(xxxx)
I am trying to evaluate the jPod PDF library, the import line:
import de.intarsys.tools.locator.FileLocator;
says it cannot be resolved. I have jPod.JAR and iscommon.jar, What other JARs do I need to get the FileLocator?
I'm creating a web-based interface for a number of different command line executables, and am using cherrypy behind apache (using mod_rewrite). I'm very new to this, and am having difficulty getting things configured properly. On my development machine, everything works reasonable well, but when I installed the code on a second machine I can't get anything to work properly.
The basic workflow for the applications is: 1. upload a dataset, 2. process the data (using python with some calls to executables using subprocess.call), 3. display the results on the web page.
After uploading and processing one dataset, everytime I attempt to process a second dataset the system stops responding. I'm not seeing any output in the terminal from the cherrypy process, or in the site log that shows any errors have occurred.
I'm starting cherrypy with the following conf file:
[global]
environment: 'production'
log.error_file: 'logs/site.log'
log.screen: True
tools.sessions.on: True
tools.session.storage_type: "file"
tools.session.storage_path: "sessions/"
tools.sessions.timeout: 60
tools.auth.on: True
tools.caching.on: False
server.socket_host: '0.0.0.0'
server.max_request_body_size: 0
server.socket_timeout: 60
server.thread_pool: 20
server.socket_queue_size: 10
engine.autoreload.on:True
My init.py file:
import cherrypy
import os
import string
from os.path import exists, join
from os import pathsep
from string import split
from mako.template import Template
from mako.lookup import TemplateLookup
from auth import AuthController, require, member_of, name_is
from twopoint import TwoPoint
current_dir = os.path.dirname(os.path.abspath(__file__))
lookup = TemplateLookup(directories=[current_dir + '/templates'])
def findInSubdirectory(filename, subdirectory=''):
if subdirectory:
path = subdirectory
else:
path = os.getcwd()
for root, dirs, names in os.walk(path):
if filename in names:
return os.path.join(root, filename)
return None
class Root:
#cherrypy.expose
#require()
def index(self):
tmpl = lookup.get_template("main.html")
return tmpl.render(usr=WebUtils.getUserName(),source="")
if __name__=='__main__':
conf_path = os.path.dirname(os.path.abspath(__file__))
conf_path = os.path.join(conf_path, "prod.conf")
cherrypy.config.update(conf_path)
cherrypy.config.update({'server.socket_host': '127.0.0.1',
'server.socket_port': 8080});
def nocache():
cherrypy.response.headers['Cache-Control']='no-cache,no-store,must-revalidate'
cherrypy.response.headers['Pragma']='no-cache'
cherrypy.response.headers['Expires']='0'
cherrypy.tools.nocache = cherrypy.Tool('before_finalize',nocache)
cherrypy.config.update({'tools.nocache.on':'True'})
cherrypy.tree.mount(Root(), '/')
cherrypy.tree.mount(TwoPoint(), '/twopoint')
cherrypy.engine.start()
cherrypy.engine.block()
For one example where this occurs, I've got the following javascript function that calls my python code:
function compTwoPoint(dataset,orig){
// call python code to generate images
$.post("/twopoint/compTwoPoint/"+dataset,
function(result){
res=jQuery.parseJSON(result);
if(res.success==true){
showTwoPoint(res.path,orig);
}
else{
alert(res.exception);
$('#display_loading').html("");
}
});
}
This calls the python code:
def twopoint(in_matrix):
"""proprietary code, can't share"""
def twopoint_file(in_file_name,out_file_name):
k = imread(in_file_name);
figure()
imshow(twopoint(k))
colorbar()
savefig(out_file_name,bbox_inches="tight")
close()
class TwoPoint:
#cherrypy.expose
def compTwoPoint(self,dataset):
try:
fnames=WebUtils.dataFileNames(dataset)
twopoint_file(fnames['filepath'],os.path.join(fnames['savebase'],"twopt.png"))
return encoder.iterencode({"success": True})
These functions work together to give the expected result. The problem is that after processing one input file, I am unable to process a second file. I don't seem to get a response from the server.
On the machine where things are working, I'm running python 2.7.6 and cherrypy 3.2.3. On the second machine, I have python 2.7.7 and cherrypy 3.3.0. While this may explain the difference in behavior, I'd like to find a way to make my code portable enough to overcome the difference in version (going from older to newer)
I'm not sure what the problem is, or even what to search for. I would appreciate any guidance or help you can offer.
(edit: Digging a bit more, I discovered something is happening with matplotlib. if I put print statments before and after the figure() command in twopoint_file, only the first one prints. Calling this function directly from a python interpreter (removing cherrypy from the equation) I get the following error:
can't invoke "event" command: application has been destroyed while executing "event generate $w{{ThemeChanged}}"
procedure "ttk::ThemeChanged" line 6 invoked from within "ttk::ThemeChanged"
end edit)
I don't understand what this error means, and haven't had much luck searching.
Old question, but I got the same problem which I fixed by changing backend in Matplotlib:
import matplotlib
matplotlib.use("qt4agg")
