Perspective Python install failure - Windows

[twmeggs]

Bug Report

Steps to Reproduce:

1. pip install numpy
2. pip install pyarrow==0.15.1
3. pip install perspective-python

Expected Result:

I would expect the install to flag any additional required dependencies [y/n] and complete successfully. Full output below, apologies it's long.

Actual Result:

  ERROR: Failed building wheel for perspective-python
Failed to build perspective-python
ERROR: Could not build wheels for perspective-python which use PEP 517 and cannot be installed directly

Environment:

Has been tried on a Windows 10 machines, separately on a Windows Server also, in both a conda virtual env and directly into a default python environment (not virtual env). The same error is received in each case.

[timkpaine]

Do you have cmake installed and on your path? The error is saying that which cmake returned no results, and the command cmake didn't exist on your path. Make sure to install a relatively recent cmake.

[twmeggs]

@timkpaine I didn't (couldn't see that dependency in the docs, but probably my bad). I have installed now, and getting a different error. Is there are particular version of MS Visual Studio that is also a requirement?

[timkpaine]

@twmeggs right now VS 17 with VC 15 https://github.com/finos/perspective/blob/master/python/perspective/setup.py#L189

There's a PR to make it configurable but it's not merged yet, it will compile with VS 15/VC 14 as well. It will compile with VS 13/VC12 but you probably need to build pyarrow yourself.

[twmeggs]

@timkpaine thank you. That's probably the issue. I have cmake installed now, but it's throwing another error. I'm running under VS 19. I'll try with VS 17 / VC 15 now.

[timkpaine]

@twmeggs I would expect it to work fine under VS19, but you should be careful if its mixing different runtimes. Please share any errors if you see them, I will look to fix them. Be aware there are some lingering windows numerical issues when using numpy types #926

[twmeggs]

@timkpaine thanks. I've for a fresh install of VS 17. I've also added the following path to my user path environment variable and the system path environment variable:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin

I'm (pretty) sure this is still something to do with my runtime setup, but it is all fresh and clean. The XXXX is where I have obscured my username. The error is as follows (note the reference to 'Visual Studio 14 2015' at the end of the error..?)

Its looking for Visual Studio 14 2015. If you grab the tarball and modify setup.py to be Visual Studio 15 2017, it should be fine. Alternatively, you can pip install from master (it looks like i bumped to 15 2017 recently), or wait a few days for the next release which will have it be a configurable argument

[twmeggs]

@timkpaine thanks. I think I might end up waiting for the new release. Trying to run the below:

pip install -e git://github.com/finos/perspective.git@v0.4.3#egg=perspective-python

and I get the following. (I feel like a proper noob - what am I doing wrong?!?):

[timkpaine]

@twmeggs given that that command is gonna checkout this repo anyway, probably better to explicitly clone and build

git clone https://github.com/finos/perspective.git
cd perspective
yarn
yarn build_python
yarn install_python

We'll be doing a release this week most likely.

[twmeggs]

@timkpaine thanks. I'll wait for the release.

[MarcSkovMadsen]

I get the same error as @twmeggs

Failed to build perspective-python

I then run the below without problems

$ C:\\Users\\masma\\source\\repos\\orsteddcsmarketsanalytics\\sandbox\\.venv\\Scripts\\cmake.exe --version
cmake version 3.16.3

CMake suite maintained and supported by Kitware (kitware.com/cmake).

Now I don't know what to do. Any help is appreciated. Thanks.

@MarcSkovMadsen thats a different error, yours is failing in cmake itself. If you activate the virtual env what is the result of cmake --version? Also what is the result of where cmake
