Installation from source fails due to missing cmake exectuable

[pk-g]

My recent installation attempts from source keeps failing with following error

"AssertionError: Could not find "cmake" executable!
Command "python setup.py egg_info" failed with error code 1"

Is this a known issue?

@bddppq Shall we add cmake in https://github.com/onnx/onnx/blob/master/setup.py#L252

[bddppq]

cmake is a system package, not a python package, so adding it to setup.py doesn't work.
It is a required dependency for building onnx now, so we should add it to our README.

[pk-g]

Thanks guys, updating the README sounds great.

@bddppq How to add it to our README? I also got the same error while running setup.py for onnx installation from source

[Seth-Julien-de-Lampon]

I get same error when using: pip install onnx
Any fix?

Installing cmake using the command "conda install cmake" worked for me

I am trying to install it on windows 10 and i am still getting the assert error.

Complete output from command python setup.py egg_info:
fatal: not a git repository (or any of the parent directories): .git
Traceback (most recent call last):
File "", line 1, in
File "C:\Users\Public\Documents\iSkysoft\CreatorTemp\pip-install-nl0d7cz_\onnx\setup.py", line 71, in
assert CMAKE, 'Could not find "cmake" executable!'

Can someone help?

@Ananyaaa CMAKE is not available. That is the problem. download cmake from here and then try running the script.

[Ananyaaa]

@Rathna21 thanks for response. I understand that cmake is not available and i installed it using https://chocolatey.org/packages/cmake. But still i am facing the same issue. I will see where cmake gets installed and see whether it actually got installed? Can anyone help on where does the cmake gets installed if i use the chocolatey?

[Ananyaaa]

Thanks @Rathna21. I have manually added the cmake to path variable. Now the earlier assert issue got resolved, but i am getting
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

Cam some one help?

from anaconda promt, which you will get after installing anaconda package, just enter conda install cmake and then in normal command prompt just run pip install <package_name>. It worked for me.

My solution is:
First, make sure you have installed camke. And use "which cmake" command to get the directory of your camke path.
Second, add the path in the setup.py file. For example, I set it as

CMAKE = find_executable('cmake') or find_executable('cmake3')
MAKE = find_executable('make') #we already have this two line in the setup.py
CMAKE = "/home/uwen/anaconda3/bin/cmake"

On a MAC, was able to install onyx once I used brew to install Cmake and protobuf (which provides the proto compiler /aka protoc) (Downloading a release and changing $PATH etc did not work).

brew install Cmake
brew install protobuf

For me, conda solution was not as useful as simple sudo apt-get install build-essential cmake

[PlinyTheMid]

try
pip3 install onnx=1.8.1
as someone suggested and then run this
pip3 install onnx-simplifier
i was using conda env, with python 3.7

I was installing unstructured and got this error "cmake is not available"
conda install cmake
then puip install <> worked
