Step 1 opencv-haar-classifier-training error

[rajarao47]

Hi,

1. I tried step 2 to step 4. Had about 675 positive and1970 negative pictures. I could generate positives.txt and negatives.txt files.
   while running step 5:(below)
   perl bin/createsamples.pl positives.txt negatives.txt samples 1700 "opencv_createsamples -bgcolor 0 -bgthresh 0 -maxxangle 1.1 -maxyangle 1.1 maxzangle 0.5 -maxidev 40 -w 24 -h 24"
   I am receiving error as below:
   it gave error as:
   Error is: syntax error near unexpected token "(".

2. I realized that I missed step 1. Hence, I restarted the process and entered the first command as below and got message as below:

---

root@rajas01:~/rajashaar2# brew tap homebrew/science
W: be careful as root.

========================================================================
You may want to update following environments after installed linuxbrew.

PATH, MANPATH, INFOPATH

(example: /usr/share/doc/linuxbrew-wrapper/examples/profile)

Don't run this as root!
root@rajas01:~/rajashaar2# Don't run this as root!

---

It indicates a warning as do not run this as root!
I have gone through previous correspondences and unable to locate any solution for this. Am I missing any step here? Please help. (Note: I am trying this on web server installed with Ubuntu.)

Regarding 1.: See #4
Regarding 2.: the error comes from the fact that you're running this on Ubuntu. brew is a package manager for macOS.

Hi Nugget,
Thanks for your help. I did more research and realized that brew package is for mac OS. (Sorry for this as I am just bit new in programming and exploring slowly)
While running step 5, I am still getting below error message as
sh 1: ### Syntax error: "(" unexpected

Kindly help.
Is there any alternate command required for Ubuntu instead of brew

Try removing the "(", ")" and whitespace from the file names.

Hi,
I have corrected the naming of the .jpg files. It worked fine now. Thanks for your help.
