matteosal opened a new issue, #21076:
URL: https://github.com/apache/incubator-mxnet/issues/21076
This looks pretty bad:
```
import mxnet as mx
import os, psutil
print('branch: ' + mx.runtime.get_branch())
print('commit: ' + mx.runtime.get_commit_hash())
def get_memory_usage():
return psutil.Process(os.getpid()).memory_info().rss / 1e+6
print(get_memory_usage())
nd = mx.nd.ones([1000000, 1000])
mx.ndarray.waitall()
print(get_memory_usage())
del(nd)
mx.ndarray.waitall()
print(get_memory_usage())
```
output:
```
