Which should be the "TARGET PATH" for this command please

If you want to build the code with cmake, you have to clone the GIT repository first, then run the setup and build commands.
git clone https://github.com/CNES/aviso-fes.git
cd aviso-fes
mkdir build
cd build
cmake … -DCMAKE_INSTALL_PREFIX=<TARGET PATH>
when I paste this last command find error {The syntax of the command is incorrect}.
Can anyone help by fixing that what should be TARGET PATH please

Followed the instructions exactly from here..

Ive been into Heroku web interface and selected buildpack of Python (hoping that might be it), but still no luck.

Any thoughts people?
Would be so grateful for any help.
Thanks again

I imported TensorFlow to the project but then removed it, when trying to delete it from the terminal it's not there (and when looking for it manually).
any help would be appreactied!

Since you should not push any generated binary file anyway, start first by removing them locally, commit and push:
git rm -r '*.so' -f
echo '*.so' >> .gitignore
But if that still fails, it means you are trying to push past commits (not just the latest one) with *.so files, even though the last commit no longer includes any such files.
If that is the case, since git filter-branch is soon deprecated, consider newren/git-filter-repo to remove any large files like those *.so ones, before pushing (or force pushing of that rewrites the content of past commits previously pushed).

There is a problem with the code, I can not find a solution

Your Problem
remote:Requested runtime (python-3.5.2) is not available for this stack (heroku-18)
Solution:
by the official website of heroku, your python version (3.5.2) isn't compatible with heroku version 18.
From Developer Webpage:
Specifying a Python version
By default, newly created Python apps use the python-3.6.8 runtime. You can also specify a different supported Python version.
Supported runtimes
python-3.7.3 on all (heroku-16, and heroku-18) runtime stacks
python-3.6.8 on all (heroku-16, and heroku-18) runtime stacks
python-2.7.16 on all (heroku-16, and heroku-18) runtime stacks

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte when deploying to Heroku

I'm trying to follow this tutorial: http://tutorial.djangogirls.org/en/index.html
I'm up to this part: http://tutorial.djangogirls.org/en/deploy/README.html
Where I am to push it up to heroku via git. I'm familiar with git just not heroku and while I know python I'm a django beginner.
When I do the command git push heroku master i get this output which prevents the app from being deployed.
Here is the error I am receiving:

does anyone have any idea why this is occurring? heroku seems nice to use, is there a better alternative/what are the best use cases for heroku? I really just want to solve this issue so I can continue the tutorial. Learning django has been a goal of mine for a while as I'm sick of Word Press and PHP development and have been a long time Python lover.
After that error when I try the next step: heroku ps:scale web=1 i get this output:
Scaling dynos... failed
! App mus tbe deployed before dynos can be scaled.
Thanks in advance.
EDIT:
Here's my requirements.txt:
Django==1.8
dj-database-url==0.3.0
gunicorn==19.3.0
heroku==0.1.4
python-dateutil==1.5
requests==2.6.0
whitenoise==1.0.6
psycopg2==2.5.4`
I have tried saving as UTF-8, ANSI, UTF-16. Same message for all of them. I even rewrote it without copy paste. Why is my first byte always 0xff regardless of encoding? What is heroku expecting and is there a way/tool to check the bytes in a txt file?

On the shoulders of the other contributors to this question, it looks like your requirements.txt file is encoded as UTF-16 little endian.
0xFF is the first character of the Byte Order Mark for UTF-16-LE, the second character being 0xFE. The traceback states that the first character is 0xFF in position 0, and it is common in Windows for files to be stored as UTF-16 with the BOM.
Try saving the requirements.txt file as UTF-8 without BOM, or as ASCII. Simple old notepad.exe might do the trick.
Edit
Not working in notepad, so use Python 3 instead:
with open('requirements.txt', encoding='utf-16') as old, open('requirements_new.txt', 'w', encoding='utf-8') as new:
new.write(old.read())
requirements_new.txt will now be encoded as UTF-8 and should work (it will probably end up as ASCII anyway).
Note that this is based on the comments and answers of others which have suggested that the troublesome file is requirements.txt.

See this answer: Deploying Django/Python 3.4 to Heroku
pip is crashing because your requirements.txt file is encoded wrong. Save it in UTF-8 ANSI encoding.

I fixed it, the problem seemed to occur only when requirements.txt was generated on windows no matter what encoding I picked. I generated the file in ascii on Linux and it worked. I then transferred the file to windows and it worked there as well. Therefore the problem must be the requirements.txt encoding as was mentioned in comments. However, the correct encoding appears to be ASCII.
