Cannot install numpy

I am new to Python. I am trying to install numpy but every time I got this error.

C:\Users\Tech Land>pip3 install numpy

Last I heard, numpy was not yet available for Python 3.9, so pip wants to build it instead of just installing precompiled binary code.

You might want to check if numpy is prebuilt for 3.9 yet, and if not, switch to Python 3.8.

Installing on windows can sometimes be tricky. The error says it can't find 'numpy.distutils._msvccompiler' in numpy.distutils and also it cannot find mkl_rt liabrary in your declared paths. You can download and install them separately and then try to install numpy again. usually, there are different files for 32 and 64 bit systems so choose the one which fits you.

pip3 install wheel

Could you try to reinstall it after executing this command?
