So I am pretty new to the ML world and currently following fastai's deep learning course. I tried to import gradio on my local machine's Jupyter. (using mamba). Whenever I try to import the module as
import gradio as gr
it gives me this error:
Traceback (most recent call last):

from __future__ import annotations
^
SyntaxError: future feature annotations is not defined
Any idea about what I need to do is appreciated.
I tried installing gradio in the environment, the error:
Looking for: ['gradio']
conda-forge/linux-64 No change
conda-forge/noarch 10.9MB # 2.1MB/s 5.3s
Pinned packages:
- python 3.10.*
Could not solve for environment specs
Encountered problems while solving:
- nothing provides requested gradio
The environment can't be solved, aborting the operation
From the traceback it looks like you're using python version 3.6.
At the moment, gradio supports python versions 3.7 and above (as seen here)
Prerequisite: Gradio requires Python 3.7 or higher, that's all!
As mentioned in this answer, the future feature annotations is only implemented in python 3.7 onwards.

I am trying to call rpy2.robjects which is giving below mentioned error. I am using rpy2 package(3.4.5) in python 3.5.10. R installed version is 3.4.1.

I am running this command from AWS EC2 instance where it is required to call an R function from python.
The same command is working in windows after setting R_HOME.
In EC2 instance, tried 2 paths for R_HOME,
os.environ['R_HOME'] = '/usr/lib64/R/'
or '/usr/bin/R'
The issue persists in both cases.
R.home is '/usr/lib64/R/' (R prompt)
rpy2 3.4.x requires Python >=3.6 as described in the documentation (installation section). The error you see is because Python 3.5 did not support typing.
You need to upgrade your Python version. Python 3.5 support ended 1 year ago and its not safe to use it - you may be exposed to unpatched security bugs. Given that support for 3.6 ends in two months I would recommend upgrading straight to 3.7 or 3.8.
I have created virtualenv for python3 using:
virtualenv -p $(which python3) ENV
Then activate the source
source /Users/myusername/ENV/bin/activate
Install the apache-airflow:
pip install apache-airflow
then which airflow yields /Users/myusername/ENV/bin/airflow
But when I try to initdb using:
airflow initdb
I get below error:

(ENV) ---------------------------------------------------------
Seems like example scripts use python 2.7 and it can't recognize the function definition syntax.
Does apache-airflow package need to be fixed by the next release or I can do something to fix this?
I tried fixing this:
Use python2.7 instead of python3
then install airflow on default python 2.7 enabled on mac but this throws other errors like package "six" is not compatible.
You need to turn off the example DAGs to be loaded in config file to solve this problem.
Anyway, it seems weird that airflow uses 2.7 Python when you told that it is installed into Python 3 virtual environment.
I've installed Qt5.2.1 / SIP 4.5.15 and PyQt5 on my Ubuntu 12.4 desktop. Everything seemed OK until I try to import QtWebKitWidgets. This module is very important in my code.
>>> from PyQt5 import QtWebkitWidgets
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name QtWebkitItems
>>>
No error raised during the installation phase. in my /opt/Qt5.2.1/5.2.1/gcc_64/lib directory I can see the corresponding Qt libs.
Does anyone have an idea ?
Thank you in advance
I'm not sure where you're getting "QtWebkitItems" from (a web-search gets no hits other than this page), but the real problem is a simple typo. The import statement should be:
from PyQt5 import QtWebKitWidgets # upper-case K!
PS: it's nicely ironic that you managed to spell it right in your question, and even highlighted it in bold!
I've just migrated from the Python 2.5 to the 2.7 runtime, and most of server I've written runs fine. However I'm occassionaly seeing this odd stack trace (I've hacked it down for brevity):
ERROR 2013-04-23 10:40:15,598 wsgi.py:235]
Traceback (most recent call last):
File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/jinja2-2.6/jinja2/environment.py", line 894, in render

File "templates/querystart.html", line 30, in top-level template code
{% for session in sessions %}
ImportError: No module named _sqlite3
I've not imported sqlite3 myself, and I don't rely on it. The code that's calling it is pretty simple (perhaps bordering on the dumb side of things):
class UserIdQuery(BaseHandler):
def get(self):
sessionQuery=Session.all().order("userid")
template_values = {
'sessions': sessionQuery,
}
self.render_template('querystart.html',**template_values)
The above simply extends the below (taken from a very helpful migration tutorial)
class BaseHandler(webapp2.RequestHandler):
#webapp2.cached_property
def jinja2(self):
return jinja2.get_jinja2(app=self.app)
def render_template(self, filename, **template_args):
self.response.write(self.jinja2.render_template(filename, **template_args))
Anyone know what might be triggering the import error? Thanks,
Appengine uses sqlite for the datastore, my bet is your python2.7 installed on OSX is missing the sqlite binary library. Do a quick test, start a python interpreter (outside of appengine) and try to import sqlite3
$ python
Python 2.7.3 (default, Sep 26 2012, 21:53:58)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3

If that fails you know you have an incomplete 2.7 runtime installed.
I was having the same problem and fixed it.
I was running python 2.7.3 that I installed from Ninite.com.
Uninstalled python, downloaded and installed 2.7.5 installer directly from python.org and problem has gone away.
I am trying to launch the hello world sample,I use TideSDK 1.3.1-beta with Tide SDK Developer,I have install all the needed components such as imagick,wix and python 2.7 ,But I am getting this error during launch :

Done launching!
I have fixed the problem , Since TideSDK comes with its own Python runtime,I created an environmental variable pointing to that python runtime so this was how I did it . [code] variable home : PYTHONHOME variable vaulue : C:\ProgramData\TideSDK\modules\win32\python\1.3.1-beta
It almost seems like it's using a different Python version, although the folder clearly says 2.7. Did you have another version of Python installed before? If so, did you change the environment variable to point to 2.7 after installing 2.7? Maybe confirm with python --version.
