what other alternatives solutions I can use
I'm using flask 2.2.2
Try
Werkzeug <= 2.1.2
flask == 2.1.2
Both of these have to be compatible. Let me know if you can work it out. the above version worked for me.

I have model trained on colab and now I want to use that in my centOS7-server like this
import json
from flask import Flask, jsonify, request
import mysql.connector as mariadb
from simpletransformers.ner import NERModel,NERArgs
model = NERModel('bert', './checkpoint-14000', use_cuda= False)
model_args = NERArgs()
model_args.lazy_loading = True
app = Flask(__name__)
#app.route('/sp', methods=['POST'])
def addOne():
try:
prediction = model.predict([json.loads(request.data)['txt']])
return jsonify({'OK': prediction[0][0]})
except Exception as e:
return jsonify({'ERROR': e})
if __name__ == '__main__':
app.run(host='0.0.0.0')

It looks like your source files are messed up. Try to reinstall the dns library. If it does not help, manually edit the file C:\Users\Aadish\AppData\Local\Programs\Python\Python39\lib\site-packages\dns\name.py to fix the problem.
All my code is on github except for the token.py file for obvious reasons.
bot.py file
I have had similar issues in the past and have resolved them by reconstructing some code so I apologize in advance if this is another one of those issues where I missed a capital or something but I have tried all the obvious syntax issues and none of them seemed to work. Atom also didn't show any errors.
Here is the whole error message:

I had a similar error just because the filename.
I am trying to create my own PyEnvironment for TF-Agents.
However, this error keeps showing up:
AttributeError: module 'tensorflow.python.ops.linalg.linear_operator_util' has no attribute 'matmul_with_broadcast'
I have found out that this seems to be an issue with tensorflow-probability, but I have installed the version tensorflow-probability=0.7.0 recommended at
https://github.com/tensorflow/agents/issues/91
I have tried reinstalling and updating
tensorflow-gpu=2.0.0-beta1
tf-agents-nightly
tensorflow-probability=0.7.0
Here is a minimal code example:
from tf_agents.environments import py_environment
class myEnv(py_environment.PyEnvironment):
def __init__(self):
pass
def _reset(self):
pass
def _step(self, action):
pass
This is the full error message when running this minimum example:

Found it!
In order to use tensorflow-gpu with tensorflow-probability, one needs to install tfp-nightly
So pip3 install --upgrade tfp-nightly did the trick
To use 2.0.0beta1 requires tfp-nightly.
I have python 2.7.9 on OS X (10.11). I have installed tweepy 3.5.0 and simplejson 3.8.1. When i write a program (IDE: textWrangler) for updating status of twitter account (by using tweepy) and run the program using command line it throws error on "import tweepy" in a program. However when i run the same code on python shell, it execute sucessfuly (without any error). Any suggestions or comments?
