Can not import minpy in Python 2.7 (anaconda): Type "MXNet" for name "reshape" has already existed

[Ruocheng Guo]

Hi,

I just installed minpy with pip install minpy, but the import failed and returned this message.
Could I fix this by doing something?
I am with MXnet 0.9.4 on Python 2.7.13 (Anaconda), CUDA 8.0 and cudnn 5.1 and they work together.

import minpy
Traceback (most recent call last):
File "", line 1, in

Please install MXNet's engine branch to properly use minpy.

Hi Larry, thanks for your fast response, I wonder how should I properly do this as I already have mxnet installed in ~/mxnet?
As I don't quite understand the relationship between mxnet and the engine branch,
I just cloned the engine branch in ~/mxnet_engine/ and ran make according to the minpy intallation instruction tutorial, no problem happened here.

In .bashrc, I have both
export PYTHONPATH=.../mxnet/python:PYTHONPATH
export PYTHONPATH=.../mxnet_engine/python:PYTHONPATH

Then I failed in run ~/mxnet_engine/python/setup.py install
it throws:

Traceback (most recent call last):
File "/home/ruocheng/mxnet_engine/mxnet/python/setup.py", line 72, in
ext_modules=config_cython())
File "/home/ruocheng/mxnet_engine/mxnet/python/setup.py", line 43, in config_cython
for fn in os.listdir(path):
OSError: [Errno 2] No such file or directory: 'mxnet/cython'

Thank you~

[Larry Tang]

Once PYTHONPATH is set up, you do not need to install through setup.py. You are good to go.

[Ruocheng Guo]

Thanks Larry, it works now.

Where is this build branch it appears to be gone.
