Hi, While I am trying to run the example from mxnet/example/gluon.

I meet this problem:

root@server:/users/yxd429/mxnet2/mxnet/example/gluon# /usr/bin/python3 image_classification.py --dataset cifar10 --model vgg11 --epochs 1
Traceback (most recent call last):
File "image_classification.py", line 30, in
from mxnet.gluon.metric import Accuracy, TopKAccuracy, CompositeEvalMetric
ModuleNotFoundError: No module named 'mxnet.gluon.metric'

I am trying to run the training no cpu. I install it as "pip3 install mxnet"

What is the problem should be ?

Best Regards,
Johnny

pip3 install mxnet installs MXNet 1 and you are executing MXNet 2 Python code with MXNet 1, which is expected to fail.

MXNet 2 is currently unreleased. You can track the status for beta release at #19139

You can use the v1.x branch to get MXNet 1 or compile MXNet 2 from source. We'll provide package on pypi once the beta is approved later. If you wish to help test MXNet 2, you can also install a nightly build pip install --pre -f https://dist.mxnet.io/python/cpu mxnet

What i did is i change the source code from mxnet.gluon.metrics to mxnet.metrics. It works now. thank you Leonard Lausen <[email protected]>于2020年10月12日周一下午7:15写道：

Hi, Leonard Actually, I follow the instructions from the tutorial from this link. I just try to run the example model here. https://mxnet.apache.org/versions/1.7/api/faq/distributed_training All the command I am using is from this link... However, the errors keep showing up. What tutorial I need to follow with ? [apache/incubator-mxnet] ModuleNotFoundError: No module named 'mxnet.gluon.metric' Best Regards, Johnny

The problem with the page is that it links to master branch, which actually should have been linked to a commit instead. i.e.

This page:
https://github.com/apache/incubator-mxnet/blame/v1.7.x/docs/static_site/src/pages/api/faq/distributed_training.md#L98
should link to:
https://github.com/apache/incubator-mxnet/blob/7efb5df7fcaaff5b1ced41b7e718e2146ed57814/example/gluon/image_classification.py

For now you can run the script from the second link

Hi, Thank you for your guys' quick response ! Hope this E-mail finds you well! I use a right image_classification.py file, however, I still have other problems. Problem One: Within the tutorial for distributed training, the information within the hostfile should be only IP address. My master can ssh to the worker nodes using command "ssh -A user@ip_address". However, if the hostfile only contains the ip_address without the user name, the ssh will be denied because of the publickkey problem. However, if the hostfile contains user@ip_address, there will be no ssh problem. Problem Two: When I try to run the command: ../../tools/launch.py -n 3 -s 1 -H hosts --launcher ssh --sync-dst-dir /users/yxd429/test python image_classification.py --dataset cifar10 --model vgg11 --epochs 1 --kvstore dist_sync There will be a errors: rsync: failed to set times on "/users/yxd429/test/.": Operation not permitted (1) How can I solve this problem ? Best Regards, Johnny

Also, even though I follow all the instructions, I still got this type of errors: What is wrong with my implementation ? root@server:/users/yxd429/incubator-mxnet/example/gluon# ../../tools/launch.py -n 3 -s 1 -H hosts --launcher ssh --sync-dst-dir /users/yxd429/test python image_classification.py --dataset cifar10 --model vgg11 --epochs 1 --kvstore dist_sync 2020-10-17 13:49:04,653 INFO rsync /users/yxd429/incubator-mxnet/example/gluon/ -> [email protected] [email protected] [email protected] [email protected]: /users/yxd429/test bash: [email protected]: command not found bash: line 0: export: `[email protected]': not a valid identifier bash: line 0: export: `[email protected]': not a valid identifier bash: line 0: export: `[email protected]': not a valid identifier python: can't open file 'image_classification.py': [Errno 2] No such file or directory bash: [email protected]: command not found bash: line 0: export: `[email protected]': not a valid identifier bash: line 0: export: `[email protected]': not a valid identifier bash: line 0: export: `[email protected]': not a valid identifier bash: [email protected]: command not found bash: [email protected]: command not found bash: line 0: export: `[email protected]': not a valid identifier bash: line 0: export: `[email protected]': not a valid identifier bash: line 0: export: `[email protected]': not a valid identifier bash: line 0: export: `[email protected]': not a valid identifier bash: line 0: export: `[email protected]': not a valid identifier bash: line 0: export: `[email protected]': not a valid identifier Best Regards, Johnny
