Exception 'Application' object has no attribute 'session'

[rrodrigueznt]

Hi! After enjoying radian on my Samsung A50, I'm now trying to do the same in my brand new A52. After installation, radian starts correctly, but some keyboard entries (delete and enter among others) head to the exception:

Exception 'Application' object has no attribute 'session'

The whole message reads:

Unhandled exception in event loop:

Press ENTER to continue...

Please, any idea about the source of the error?

Thanks!

What version of radian you have? Where did you install it from? radian doesn't have a file called "keybindings.py".

~ $ radian --version
radian version: 0.3.4
r executable: /data/data/com.termux/files/usr/lib/R/bin/R
r version: 4.1.0

python version: 3.9.7
~ $

I would swear that I followed the instructions in the README.md but using pip3 instead of pip. But, radian 0.3.4?!

Thanks!

Perhaps trying to update radian pip3 install -U radian

Thanks. Here what I get:

Then, I run pip3 install wheel and pip3 install -U radian again. Here what I get now:

~ $ radian --version
radian version: 0.5.12

r version: 4.1.0

And radian is working now! Please, could a note on this issue in README.md be helpful? Was it a particular issue of my installation?

Thanks for your help!
