Error on Raspberry PI 4 while opening TensorFlow.
I came by this error after installing TensorFlow in RPI 4
can you guys find a fix?
error on Raspberry PI 4
tensorflow/core/platform/hadoop/hadoop_file_system.cc:132] HadoopFileSystem load error: libhdfs.so: cannot open shared object file: No such file or directory)
Your are using a bleeding edge python software for tensorflow. I believes it is python 3.7 or python 3.8 or something. Try to downgrade your python to 3.6.5 or other compatible version by refereing documentation.
@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??
@arunksoman i installed tensorflow from the below given link
and i installed it without entering into virtual environment
but this 10% memory issue is a serious pain
@arunksoman tensorflow 2.0.0 version had been installed
Ensure that you are installed tensorflow 1.x since screenshot of your code shows something like
from keras.layers.convolution import covolution2D
It is not correct in case for tensorflow 2.0 since keras api is part of tensorflow itself.
Another thing is try to expand your file system. It should be do with your own risk.
- Navigate to Advanced options
- Select advanced options and hit enter(I believes tab key is useful here)
- Choose Expand File System and hit enter finish.
- Then your pi may prompt to reboot. If it didn't run. Execute
- Then execute following commands one by one:
$ sudo apt-get purge wolfram-engine $ sudo apt-get purge libreoffice* $ sudo apt-get clean $ sudo apt-get autoremove
- Then increase swap memory by editing following file swapfile:
$ sudo nano /etc/dphys-swapfile
- It will open nano editor. Navigate to variable
It indicates your current swap is only 100mb.
So you just have to increase by commenting down this line and increase to appropriate value something like shown below for 2GB swap:
- Save the file and exit nano editor.
I believes if it did not helped you, you have to think about MOVIDIUS or NVIDIA Jetson nano etc.
@arunksoman i'll try this method, but while executing swap command, will the rasbian os and the files it contains be effected??
@sreu13 I edited comment please read that again. Most probably it will not effect your file system. In some scenarios it can create worse effect.
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
- sending image from rpi4 to cloud
- using this cloud for running prediction
- 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?
I have made a custom board with Atmega328P SMD IC and now I am having a problem flashing it. I have flashed multiple chips like these earlier, however this time I am having a hard time figuring out the issue.
I am using Arduino UNO as an ISP programmer to burn bootloader but getting responses like Attempt 1 of 10 - stk500() is not responding etc., like that. I need some help regarding this issue.
Any kind of help will be greatly appreciated. Please ask me for any additional information that I might have not mentioned in this post.
Thanks in advance.
I have been facing this problem recently while I run the program the output terminal just shows scanned text and the android virtual device is not opening. I have reinstalled the SDK but the problem still persist.!
Hi, I was looking for a reliable carbon monoxide sensor, I tried the MQ7 sensor, but it has a preheat time of 48 hours and a sensitivity range from 20ppm-2000ppm, and my application requires 1ppm to 1000ppm. let me know if anyone working with a similar sensor or use case!
@milanvarghese No, the battery comes into the play only if there is no power from the solar cell. It's like inverters in our home. They activate only if main power is gone, rest of the time they keep charging. similarly here the direct power will be coming from the solar cell, only if the solar cell can't produce enough voltage battery comes into the loop and starts providing voltage to our circuit.
@kowshik1729 I have seen this, but doesnt it damage that battery? dischargeing and charging at the same time?
