@arunksoman , any idea on this

@salmanfaris actually not at all solved!!..the problem is that...i do not know how to send data from raspberry pi to Google vm and get the results back from google vm to RPI4. I've researched a lot online...but cant find a proper route

@arunksoman thankyou so much...your reply really busted the stress out of me...can you help with any documentations which i could possibly go through

@arunksoman hi,..
actually at this point of time, I'm not willing to risk RPI4,....i thought of connecting the rpi4 to google cloud (already have an account with $300 credit) and proceeding with the code.
but i do not know if the below process can be executed

1. sending image from rpi4 to cloud
2. using this cloud for running prediction
3. the above two processes should be automated and image should be sent to cloud when pi boots up(VM engine can be activated whenever nessesary)

is this possible?

@arunksoman i'll try this method, but while executing swap command, will the rasbian os and the files it contains be effected??

@arunksoman tensorflow 2.0.0 version had been installed

@arunksoman i installed tensorflow from the below given link

https://maker.pro/raspberry-pi/projects/how-to-set-up-the-machine-learning-software-tensorflow-on-raspberry-pi

and i installed it without entering into virtual environment

but this 10% memory issue is a serious pain

@arunksoman hi, i've run this code using python 3.7 on anaconda and it worked fine.
but as i run this on RPI 4, it showed the Hadoop error. I then updated the libraries and Hadoop error was solved..
now there is a new error

also can you take a look in the 10% memory error?...like what can be possibly done there??

@salmanfaris i know there was a delay in replies, i thought of finishing the project and replying here!....
i ddnt get the exact reason, but the problem was solved

what i did was , label binarized was working fine when i did created the training model. So i loaded my training model and deleted the script for the training procedure. i ended up with the code given below. and it worked up fine.

Hi,
I came by this error after installing TensorFlow in RPI 4
can you guys find a fix?
error on Raspberry PI 4
