The program cannot run after installation

[Li-Zongshen]

I used Windows Notepad to open the install.sh file and then partially paste the code of this file during installation due to my network issues. In the end, I successfully executed all the commands and checked them without any errors.

My PiDNG library was installed using the following link for teaching: https://github.com/schoolpost/PiDNG ）

I downloaded all the DCP files using this link and renamed them as basic, neutral, and skin and sky, and finally placed them in the profiles folder: https://github.com/davidplowman/Colour_Profiles/raw/master/imx477 ）

(I also installed the keyboard module and ImageTk module myself based on the error message. The commands used were: pip3 install keyboard, sudo apt-get install python3 pil python3 pil. imagetk)

But the error message displayed when I finally ran the program camera.py is:

% Run camera. py

Mmal: mmal_ VC_ Component_ Enable: failed to enable component: ENOSPC

Traceback (most recent call last):

I tried adding a line of code 'camera. close()' before line 22, but it didn't work

My camera can execute the command raspistill - v normally and display a preview window

My system is:

Linux raspberrypi 4.19.97-v7l+# 1294 SMP Thu Jan 30 13:21:14 GMT 2020 armv7l GNU/Linux

I don't know what to do, please help me

@Li-Zongshen I am sorry. I missed the notification for this issue.

What Raspberry Pi device do you have?

Also there is no need to separately install PiDNG, DCP profiles, etc. yourself, the install-camera script should install the proper versions for you, provided you have followed all the steps here: hhttps://github.com/eat-sleep-code/camera/tree/master#getting-started

I was using Raspberry Pie 4b4g to use this software.My Raspberry Pie unable to download libraries and software by accessing Github because I am in China.I have already solved this error.The reason for this error is that I did not set the Memory Split value to a value of at least 256MB.However, there is still a problem with this software that cannot be run by clicking an icon.I wrote a shell script to solve this problem.And then there are frequent parameter adjustments that can cause the preview box to disappear and other issues, even causing my raspberry pie to freeze once.Then there are frequent parameter adjustments that can cause the preview box to disappear or the software to freeze. I used Ctrl+C to stop the program and ran the UI, which still displayed on the screen. This even caused my Raspberry Pika to freeze once.

I have not seen the issue with the freezing. Be sure you have a high quality power supply. The power regulation the Raspberry Pi isn't the best and can result in undervoltage warnings. If the power dips below the expected amount it can lead to all sorts of issues, including lockups.

In addition, there is a newer version of the camera software that is under development, but video functionality is not working yet.
