[GitHub] chsin opened a new issue #9044: [scala] run_gan_mnist.sh fails
chsin opened a new issue #9044: [scala] run_gan_mnist.sh fails
URL: https://github.com/apache/incubator-mxnet/issues/9044
## Description
Was able to built libmxnet.so, and successfully build the Scala package, but run_gan_mnist.sh fails.
## Environment info (Required)
I had to change diagnose.py:113 to except IOError as e: since FileNotFoundError is only on Python 3.

java: symbol lookup error: /tmp/mxnet1076674076824248309/mxnet-scala: undefined symbol: cblas_sgemm
```
## What have you tried to solve it?
1. Check the links in libmxnet.so are there:
```
bash-4.1$ ldd lib/libmxnet.so | grep blas
libopenblas.so.0 => /scratch/cahsin/local/lib/libopenblas.so.0 (0x00007f86e2406000)
```
2. Check the built openblas from https://github.com/xianyi/OpenBLAS, but that doesn't seem to be the issue since the cblas function is there:
```
bash-4.1$ nm /scratch/cahsin/local/lib/libopenblas.so.0 | grep cblas_sgemm
0000000000090380 T cblas_sgemm
```
