i have problem with pyinstaller i use library opcua for comunication, with normal run in pycharm everything works correctly, after create .exe with pyinstaller after few second or minute the comunication stops.
from opcua import Client
from opcua.crypto import security_policies
from opcua.ua import MessageSecurityMode
from opcua import ua
def connect(self):
try:
self.client.set_security(policy=security_policies.SecurityPolicyBasic256Sha256,
certificate_path=self.root_path+CERT_RELATIVE_PATH,
private_key_path=self.root_path+PRIVATE_KEY_RELATIVE_PATH,
mode=MessageSecurityMode.SignAndEncrypt
)
self.client.application_uri = "urn:script:opcua"
# self.client.secure_channel_timeout = 10000
self.client.session_timeout = 60000
self.client.connect()
self.root_node = self.client.get_root_node()
self.call_method('ns=2;s=/Methods/GiveUserAccess', 'OpcUaClient', 'GudWrite')
return True
except Exception:
self.main_log.info('unable to connect to nc: {}'.format(traceback.format_exc()))
raise custom_exceptions.UnableToConnect()
def get_battery_100(self):
return self.client.get_node('ns=2;s=/NC/_N_NC_GD2_ACX/DG_BATTERY_TIME').get_value()
This is the error after some data exchange:

do you know if there is any modification to make to make it work in pyinstaller for comunication0?
(class with this module is call with a thread)
BadSecurityChecksFailed related to security, are you shure you are destribute the correct certificates? Or if you are using your client on another device, are you matching the correct hostname/ipaddress in the certificates?
I solved. when i created the .exe file with pyinstaller i copied the .der and .pem certificates (all in the same pc) but if i delete them and with python I recreate them automatically, the program works correctly, instead with old certificates, the connection is unstable.

[LATEST UPDATE] Thanks to Jack's enormous help!!! I managed to connect to the Cloud SQL postgres DB and read/write my dataframes to the database. However, I am still experiencing the same error that I experienced previously, which is...
struct.error: 'h' format requires -32768 <= number <= 32767
This error doesnt happen when the dataframes are small, compact and columns do not have too many NaN values in them. However, when there are many NaN values in the columns, the program throws the following error.
Separately I have tried using df = df.fillna(0) to fill the NaN values with 0. But it did not work as well, and the same error surfaced. Please help!

concurrent.futures._base.TimeoutError:
I have setup a postgresql in GCP's Cloud SQL. I am trying to connect to it using
google.cloud.sql.connector. I have created a Service Account from the GCP Console, and downloaded the json keys.
I want to use a service account , credentials/ keys (in the format of reading a .json file placed in the same directory as my main.py code) to authenticate access to cloud_sql.
I am trying to authenticate, but I keep getting an error that says that the service account json file was not found.
Can anyone help to figure out how to fix this error? Thank you!
import pandas as pd
from google.cloud.sql.connector import connector

# configure Cloud SQL Python Connector properties
def getconn():
conn = connector.connect(
os.environ['LL_DB_INSTANCE_CONNECTION_NAME'],

user=os.environ['LL_DB_USER'],
password=os.environ['LL_DB_PASSWORD'],
db=os.environ['LL_DB_NAME'])

WHERE table_schema = 'public'""").fetchall()
for table in results:
print(table)
if __name__=="__main__":
# Set the Google Application Credentials as environment variable
os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = os.path.join(os.getcwd(),"Google-Credentials-LL-tech2.json")
# create connection pool to re-use connections

# Show what tables remain in database
results = db_conn.execute("""SELECT table_name FROM information_schema.tables

for table in results:
print(table)
The error you are seeing means that the .json file is not being found. This is most likely being caused by os.getcwd() which gets the path of the current working directory from where main.py is being called. This leads to errors if you are calling the file from anywhere other than the parent directory.
Working case: python main.py
Error case: python folder/main.py
Change the line where you set credentials to the following:
os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = os.path.join(os.path.dirname(os.path.abspath(__file__)),"Google-Credentials-LL-tech2.json")
This will allow the credentials path to be properly set for all cases of where your main.py is called from.
Responding to your latest update of the error.
First, make sure that your service account has the Cloud SQL Client role applied to it.
Secondly, try executing the following basic script prior to your custom configuration, this will help isolate the error to the Python Connector or the service account/implementation.
The following should just connect to your database and print the time.
from google.cloud.sql.connector import connector
import sqlalchemy
import os
os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = os.path.join(os.path.dirname(os.path.abspath(__file__)),"GSheet-Credentials-LL-tech2.json")
# build connection for db using Python Connector
def getconn():
conn = connector.connect(
os.environ['LL_DB_INSTANCE_CONNECTION_NAME'],
"pg8000",
user=os.environ['LL_DB_USER'],
password=os.environ['LL_DB_PASSWORD'],
db=os.environ['LL_DB_NAME'],
)
return conn
# create connection pool
pool = sqlalchemy.create_engine("postgresql+pg8000://", creator=getconn)
def db_connect():
with pool.connect() as conn:
current_time = conn.execute(
"SELECT NOW()").fetchone()
print(f"Time: {str(current_time[0])}")
db_connect()
If that still gives the error, please provide the full stacktrace of the error so that I can try and debug it further with more info.
I'm new to pybliometrics. I opened the python pybliometrics documentation and ran this example:
from pybliometrics.scopus import AffiliationSearch
query = "AFFIL(Max Planck Institute for Innovation and Competition Munich)"
s = AffiliationSearch(query)
print(s)
But it throws a pybliometrics.scopus.exception.Scopus401Error error.

As I understand it, I need to specify the API keys. How to do it?
You're right, according to https://pybliometrics.readthedocs.io/en/stable/access.html#error-messages 401 is most likely due to a missing key.
As the documentation on the configuration states, pybliometrics starts a process in the beginning to create the config. It asks for the API keys, and more. It seems you skipped this.
To manually create the config, go to your home directory (~/ on *nix systems) and create the folder .scopus (the dot is important). In there, create the file config.ini with a normal text editor. It needs to have at least those two sections, Directories and Authentication as shown on the documentation on the configuration.
Or simply reinstall pybliometrics and don't skip the set-up prompt in the beginning.
Admittedly, I am fairly new to postgresql and pgadmin, but after spending a day learning it, with pgadmin4.4.1 I was able to backup tables and restore them in various different formats, currently, the format of choice is plain text, so that I can actually read the backup file to see what it is doing and also my database is tiny, but large enough to not want to type in every entry by hand.
Since updating to pgadmin4.4.2, the restore function does not work. I provides a green box saying restore job created, yet no data is added to the database. This was not the case yesterday, it would just restore the data.
Does anyone know what defaults might possibly have changed in the update that will be preventing my restore job from actually running? I am assuming that it is created and waiting in a queue somewhere that I can't find in order to actually run the backup.
Here is the last error from the log file. Apologies for the delay in replying.

OverflowError: MongoDB can only handle up to 8-byte ints
If I look in my database tables, everything seems okay except a couple fields.
In auth_user (not sure about this one):
registration_id:""
In auth_event (I'm assuming this should not be null):
user_id:null
What is the best way to resolve this? If possible, I'd like to use MongoDB for all database transactions (including access control / authentication).
UPDATE: You can avoid this by upgrading to the latest version of Web2py. This is now fully supported so you do not need to use two different databases.
I wasn't able to solve this problem directly, but I was able to create a work-around. In db.py, I define two separate database connections:
db = DAL('sqlite://storage.sqlite',pool_size=1,check_reserved=['all'])
db1 = DAL('mongodb://localhost:27017/collection')
I call db (eventually a mysql database) on all auth functions (registration, login, is logged in checks), while handling everything else (including detailed member profiles) in mongo. I often bypass db1 DAL entirely by using the pymongo API.
I need to create a small WebDAV client that just upload files on the server.
I've found "requests" library that seems to be very easy to be used but I'm not able to use it properly.
The client should transfer binary files - so I've used the example bellow:
>>> url = 'http://IPADDR/webdav'
>>> files = {'report.xls': open('report.xls', 'rb')}
>>> r = requests.post(url, files=files)
from http://docs.python-requests.org/en/latest/user/quickstart/#post-a-multipart-encoded-file.
For me it's not working, I have the following error:
File ".../site-packages/requests/packages/urllib3/connectionpool.py", line 260, in _make_request
conn.request(method, url, **httplib_request_kw)
File ".../httplib.py", line 941, in request

File ".../httplib.py", line 795, in _send_output
msg += message_body
UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 147: ordinal not in range(128)
Should be the input file somehow encoded? (I didn't found anything related in the "requests" documentation).
After some debugging, I've actually found what's happening.
I was able to fix the issue by removing the following import in my script:
from __future__ import unicode_literals
This import seems to cause unwanted string conversions in urllib3 (which requests relies on).
As requests' author explained, this issue should be filed against urllib3.
