systrace: can't create /sys/kernel/debug/tracing/trace_marker: No such file or directory

I try to do a systrace of a react native app running on android:
/home/a/Android/Sdk/platform-tools/systrace/systrace.py --time=5 -o trace.html sched gfx view -a com.mypackage
This is the error I get, but trace_markers seem to be defect:
These categories are unavailable: sched

I have generated the template using command $ culebra -U -o mytest.py and using for com.csr.csrmeshdemo:id/powerSwitch to turn on and off the switch.
It worked fine for first time but after restarting system for another issue I am unable to run my python script. getting error like this:

Latest AndroidViewClient/culebra 11.5.7 adds more verbose information about the exception and would let you trace the root cause easily.

Error when trying to use Android systrace.py on Linux Ubuntu

I am trying to run Systrace but I get an error when I run the command.

I am currently running Ubuntu with Android SDK 5.1.1 installed along with Android Studio. Below is are my PATH export in .bashrc:
export PATH="~/Applications/android-studio/bin/:$PATH"
export PATH="~/Android/Sdk/platform-tools/:$PATH"
export PATH="~/Android/Sdk/tools/:$PATH"

Even though the answer is accepted, for those who face this problem in the future;
Run systrace from /platform-tools directory(adb is in /platform-tools directory) not from /platform-tools/systrace directory. E.g.
.../platform-tools$ python systrace/systrace.py

I fixed the issues by changing my PATH export to be specified by absolute path instead of relative path. This means, I can't define my home directory using ~/..., I have to use /home/username/....
export PATH="/home/user1/Applications/android-studio/bin/:$PATH"
export PATH="/home/user1/Android/Sdk/platform-tools/:$PATH"
export PATH="/home/user1/Android/Sdk/tools/:$PATH"
However, it is not clear to me why systrace.py won't properly run when PATH is defined using ~/... instead of /home/username/.... ADB works perfectly fine when the PATH is defined using ~/....

Error when trying to use android systrace.py line 135

New to android and wanted to do a little debugging with the systrace tool however I am unable to run the tool on the emulator (tried running the python script with python 2.0.1, 2.7.x, 3.x) as well as using ADT.
However they all produce different errors:
Developers | Systrace claims that it requires 2.x so using Python 2.x and executing python command systrace.py --help, I get:

OSError: [Errno 2] No such file or directory when running systrace.py

I'm currently trying to run the systrace python script that is included in the platform-tools folder and I'm getting the following error:
File "systrace.py", line 274, in <module>
main()
File "systrace.py", line 60, in main

I'M running on Ubuntu 12.04 LTS. Here is the command I'm using to run systrace:
sudo python systrace.py -o output.html
NOTE: The sudo is in order to avoid the following error:
File "systrace.py", line 274, in <module>
main()
File "systrace.py", line 63, in main
os.execv(legacy_script, sys.argv)
OSError: [Errno 13] Permission denied
After doing some searching around the web I found that one solution was to add the adb to my PATH variable. I added the platform-tools directory to my PATH and I'm still getting the same error. I went ahead to check the code that is causing the problem and apparently its this snippet:
adb = subprocess.Popen(getprop_args, stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
where getprop_args is defined as follows:
getprop_args = ['adb', 'shell', 'getprop', 'ro.build.version.sdk']
From what I understand the code is trying to run the following command:
adb shell getprop ro.build.version.sdk
I ran the command in console and it work with no problem. I also copied both lines of code and ran them in python interpreter and it ran without a problem. I really don't know how to solve this issue. Does anyone know of a possible solution?

Ok so I found out what the problem was. The problem was the sudo that I was putting right before python systrace.py -o output.html I didn't know but I guess the PATH variable is different when using sudo, than when not using it. So the PATH in sudo didn't have the platform-tools directory. So I removed the sudo and I was getting the following error:
File "systrace.py", line 274, in <module>
main()
File "systrace.py", line 63, in main
os.execv(legacy_script, sys.argv)
OSError: [Errno 13] Permission denied
To solve this problem I ran the following command on the legacy_script:
$chmod +x ./systrace-legacy.py
And now I was able to run the systrace script without a problem :P

this problem is causing by PATH. adb path should put the end of the other path.
for example:
$ sudo gedit /etc/environment;
PATH="...:~/softAddr/adt-bundle-linux-x86_64-20140624/sdk/platform-tools:~/softAddr/adt-bundle-linux-x86_64-20140624/sdk/tools"
not:
PATH="~/softAddr/adt-bundle-linux-x86_64-20140624/sdk/platform-tools:~/softAddr/adt-bundle-linux-x86_64-20140624/sdk/tools:..."
