- I got the same error in
nnabla==1.30.0.
- After that, if numpy's version is upgraded to
1.22.4, I can import nnabla.

- I got the same result in
nnabla==1.30.0. - But, I have not tried the smallest version of numpy that eliminates the error.
- I would like you to try to reproduce this problem.
- Then, if there is a problem, please update the required version of numpy.
- numpy [required: >=1.20.0, installed: 1.22.4]according topipdeptree.

Thank you for reporting.
I think we are running nnabla with latest numpy, so we'll try to reproduce your issue.
TomonobuTsujikawa commented
Ah, I misunderstand the version, it is numpy 1.21.x... All right, your investigation might be correct.
We will check and add requirement for pip.

@TomonobuTsujikawa I'm experiencing a similar issue with nnabla 1.32.0. I'm using Windows 10, Python 3.8, and whatever numpy comes with pip install nnabla:

@JeffreyCA
Sorry for inconvenience, we could not include the fix in v1.32.0.
Now we fixed this numpy incompatibility issue in master branch by #1139
And, it will be released in next version.
TomonobuTsujikawa commented
We're sorry for waiting long time for this numpy issue.
If you face these errors, please downgrade (or upgrade) numpy version until a new version (v1.33.0) is released.
Here is the way to install appropriate numpy for nnabla v1.32.x:
pip install -U numpy==1.23.5After nnabla v1.33.0, the appropriate numpy version will be installed by automatically.
TomonobuTsujikawa commented
nnabla v1.33.0 has been released, so we hope this issue has now been resolved.
IsaraAomi commented
Sorry for the late reply.
I have confirmed that the problem has been resolved in v1.33.0.
Thank you so much.

sorry, I face the similar issue when I am doing with the latest version 1.35.1, I cannot import nnabla in numpy==1.23.5 @TomonobuTsujikawa
TomonobuTsujikawa commented
We have already taken measures to address this issue by #1139
The latest nnabla (v1.35.1) will install numpy v1.23.5 normally, so it should work.
Here is my instruction, and it seems to work correctly on my environment. Could you please check?
$ python --version
Python 3.8.10
$ pip --version
pip 20.0.2 from /tmp/a/test/lib/python3.8/site-packages/pip (python 3.8)
$ pip install -U pip
(snip)
$ pip --version
pip 23.1.2 from /tmp/a/test/lib/python3.8/site-packages/pip (python 3.8)
$ pip install nnabla
(snip)
$ python -c "import nnabla"
