[GitHub] [incubator-mxnet] aaronmarkham opened issue #12373: macOS installation (build from source) fails

["aaronmarkham (GitHub)" <gi...@apache.org>]

Running the installation for "build from source" for mac fails.

https://mxnet.incubator.apache.org/install/index.html?platform=MacOS&language=Python&processor=CPU#validate-mxnet-installation

It has you run a shell script.

Two issues:

1. It detects a previous version, but fails to remove it.
```
MXNet 1.0.0.post4 is already installed.
This installation might interfere with current installation attempt.
Do you want to remove installed version? (y/n): y
Skipping mxnet as it is not installed.
MXNet 1.0.0.post4 is already installed.
This installation might interfere with current installation attempt.
Do you want to remove installed version? (y/n): y
Skipping mxnet as it is not installed.
MXNet 1.0.0.post4 is already installed.

```

2. Then later the test fails:
```

:-(
```

Importing mxnet yields a warning:

```
>>> import mxnet
dyld: warning, LC_RPATH ${ORIGIN} in /Users/markhama/Library/Python/2.7/lib/python/site-packages/mxnet/libmxnet.so being ignored in restricted program because it is a relative path

If we go with https://github.com/apache/incubator-mxnet/pull/12388 then this issue will be moot. We wouldn't be using that script. However, if we get the script updated and working, it can be an alternative install option for users.

@aaronmarkham Seems like the validate-mxnet-installation anchor link does not go to the intended page. Can you please check the URL once again ?

Also, I tried install MXNet on MacOS and I did not run into any issues. 
I used this instruction page to do so : https://mxnet.incubator.apache.org/install/osx_setup.html

#12388 was merged and that removed this script from the instructions. I also moved validation to a separate page to reduce the complexity of the install page. 
@piyushghai Glad to hear that the instructions work for you!

This issue can be closed.
