Can't import gensim library - Python 3.8.5 + numpy 1.20.2 #3097

norbertgieruc · 2021-03-31T13:40:13Z

Hi,

I was trying to run script that I created some time ago on Python 3.6.5 and it seems to don't work anymore. I can't import the library. Upgrading numpy didn't help. Can I ask for a solution to this problem?

Thanks for reporting. That's weird – my understanding was that upgrading numpy should help.

Related to #3095 and numpy/numpy#16938.

@mpenkov could you have a look please? This Numpy's C API incompatibility fuckup seems critical, will hit a large percentage of Gensim users.

mpenkov · 2021-03-31T14:49:57Z

@norbertgieruc What version of numpy did you upgrade to?

Also, what O/S?

norbertgieruc · 2021-03-31T14:53:17Z

Current:
Windows 10
Numpy 1.20.2

If you are asking what Numpy version were working previously I don't remember. I created that code like 1 year ago and just wanted to rerun it now and failed.

mpenkov · 2021-04-01T00:55:18Z

@piskvorky Something really strange is happening with numpy.

In this ticket, the user is still unable to import gensim even after upgrading numpy to 1.20.2, when using Python 3.8.5 on Windows. For that configuration, Appveyor built the wheels using numpy 1.20.1 (see https://ci.appveyor.com/project/piskvorky/gensim-wheels-2x1bk/build/job/7bhvjbjhcr9mivx7#L1372). If numpy version 1.20.2 is incompatible with wheels built against 1.20.1, then we're in trouble.

piskvorky · 2021-04-01T07:12:50Z

Indeed. I'll open a ticket at numpy, but can you clarify one thing for me please? How come the wheels used numpy 1.20.1, when you switched to using oldest-supported-numpy? I don't understand how that can be.

Because if we're building against the latest version, that's against the official numpy recommendation, so I guess problems are to be expected.

BTW, Numpy have a nice signpost page for new issues: https://github.com/numpy/numpy/issues/new/choose
Let's see how they did it and do it for Gensim too :) Many don't read / respect our current issue template.

mpenkov · 2021-04-01T09:23:36Z

How come the wheels used numpy 1.20.1, when you switched to using oldest-supported-numpy? I don't understand how that can be.

It could be a bug in oldest-supported-numpy. Its choice of versions for Windows builds is quite strange:

Py3.6: numpy 1.19.5
Py3.7: numpy 1.20.1
Py3.8: numpy 1.20.1

mpenkov · 2021-04-01T09:38:46Z

No, wait, the problem is that Windows builds happen using Appveyor, not Travis CI, and that uses a different build mechanism. This mechanism isn't picking up oldest-supported-numpy. I'll build new wheels and do a bugfix release. That should fix the wheels for Windows users (but, as I mentioned above, I'm not sure that will fix the ImportError that OP is having).

Have non-Windows users reported similar problems?

piskvorky · 2021-04-01T09:42:39Z

Oh crap, I just submitted the Numpy ticket :)

mpenkov · 2021-04-01T09:51:54Z

I think the Numpy ticket is still valid. We built the wheel using 1.20.1, and the user is unable to use it with numpy 1.20.2 installed. Is that expected? We built with an older version than what they have, so things should work, right?

piskvorky · 2021-04-01T10:16:54Z

I think so. @norbertgieruc how did you install Gensim? Was it a standard pip install from PyPI?

Because I see some Anaconda3 in your stack trace above. I'm not sure what these guys do exactly, but we do not support non-standard 3rd party repositories (packaged and controlled by someone else).

norbertgieruc · 2021-04-01T10:47:45Z

@piskvorky Yes, it was standard pip install via anaconda prompt.

llunn · 2021-04-01T11:21:09Z

We're also experiencing this error in one of our projects that uses gensim, but I don't think your lib is the issue here. Our source of the problem is coming from a scikit-learn package: hdbscan (https://github.com/scikit-learn-contrib/hdbscan)

Problem occurs in both Windows (python 3.8.8) and macOS (python 3.8.5).

I'm not able to disclose the full stack, but the snippet that matters:

  File "C:\Users\Brent\AppData\Local\Programs\Python\Python38\lib\site-packages\hdbscan\__init__.py", line 1, in <module>
    from .hdbscan_ import HDBSCAN, hdbscan
  File "C:\Users\Brent\AppData\Local\Programs\Python\Python38\lib\site-packages\hdbscan\hdbscan_.py", line 21, in <module>
    from ._hdbscan_linkage import (single_linkage,
  File "hdbscan/_hdbscan_linkage.pyx", line 1, in init hdbscan._hdbscan_linkage
ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

In our particular case, we're also using tensorflow 2.4.1, which fails when using numpy 1.20.x, so we seem to be in a difficult spot atm. Dependencies are fun, right?

piskvorky · 2021-04-01T11:30:49Z

@llunn it's possible the issue with HDBScan is a separate one. Do they use oldest-numpy-version? Probably best to open a ticket at HDBScan, or chime in at numpy/numpy#18709, so the numpy devs have a bigger picture. Whatever happened over there at numpy, it clearly wasn't communicated well enough downstream.

llunn · 2021-04-01T11:40:14Z

@piskvorky honestly I'm not sure what HDBScan does or how to check on that oldest-numpy-version. Will be amplifying your issue at numpy; intent here was to let you know it isn't specific to this project.

mpenkov · 2021-04-01T13:10:04Z

In our particular case, we're also using tensorflow 2.4.1, which fails when using numpy 1.20.x, so we seem to be in a difficult spot atm. Dependencies are fun, right?

@llunn Please mention the numpy versions for each of your environments (Windows/Mac, Python version, etc) that exhibit the problem. I'm trying to pin down the cause, seeing a matrix with what works and what doesn't would be helpful.

mpenkov · 2021-04-01T14:18:24Z

https://pypi.org/project/gensim/4.0.1/

llunn · 2021-04-01T15:27:43Z

@mpenkov Full disclosure here, our project is unlikely be a good case study to use. We have had to drop our gensim version to < 4.0.0 due to breaking changes in another dependency ( top2Vec ) that imports gensim.

Completely recognize that our problem is completely outside of your area of concern and it is almost certainly unrelated to gensim. That being said, I'm not sure any of the information below can be considered relevant, so I defer to your expertise in this project and provide it for whatever value it might have.

We tried today:

In all cases, using gensim 3.8.5

Platform	Python Version	NumPy Version
Windows	3.8.8	1.20.2
Windows	3.8.8	1.19.5
MacOS	3.8.5	1.20.2
MacOS	3.8.5	1.20.1
MacOS	3.8.5	1.20.0
MacOS	3.8.5	1.19.5

Based on the response over at NumPy, I don't find it surprising that none of these work since the hdbscan import is surely using the same numpy version in their pyc.

What follows is unrelated to the gensim project, but for awareness of how I joined this conversation:

As mentioned above, top2vec uses gensim as a dependency;
Top2Vec requires NumPy > 1.20, which has an import for tensorflow.
Tensorflow 2.4.1 requires NumPy < 1.20. The actual requirement for tensorflow is ~1.19.2, maybe. I don't have the exact version in console history atm.
We also using scikit_learn (which is where the hdbscan dependency comes from).
Our particular trouble arose due to top2vec does not work with NumPy < 1.20, and our tensorflow model training code doesn't work with NumPy > 1.19.x.

** Edit note**
I feel like it is worth pointing the incompatibility that is introduced for projects that require numpy >= 1.20.0 with tensorflow. This likely for sure impacts gensim.

piskvorky · 2021-04-01T17:40:07Z

Seems fixed now with Gensim 4.0.1.

@llunn I'd recommend you urge your dependencies (top2vec etc) to upgrade using the Gensim 4 Migration Guide. Because Gensim 4 is miles ahead of 3.8 in terms of performance and memory, and also fixed a number of important bugs.

mpenkov · 2021-04-02T10:14:03Z

@norbertgieruc Can you please try gensim 4.0.1 and let us know whether the problem still persists?

0x0badc0de · 2021-05-17T13:46:46Z

gensim 4.0.1 fails on python 3.9.5 with the same error when installed with pip install --no-cache-dir -r requirements.txt. If gensim is removed from requirements.txt and installed later with pip install gensim - works as expected.

piskvorky · 2021-05-17T16:52:49Z

Hm. Maybe something to do with the fact we don't distribute Python 3.9 wheels yet?

Although I don't see how that could affect whether you use requirements.txt or not. Some disfunctional order-of-resolving-conflicting-dependencies in pip?

0x0badc0de · 2021-05-17T17:21:31Z

Did some testing. Changing packages order in requirements.txt doesn't help. Also, we don't install numpy explicitely - it's brought in by some other packages. What works: using python 3.8, installing gensim after numpy, installing numpy==1.20.3. Doesn't work: installing gensim==4.0.1 along with numpy==1.19.5 (requirement of other packages) on python 3.9.

I still have a compatibility issue when running : pip install numpy==1.19.4 pip install tensorflow=2.5.0 pip install gensim==4.0.1

On Ubuntu 18.04, with Python 3.9.5 (installs made inside docker container).

I get the following exception when trying to import gensim: ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject. Not sure how i can make this work, I tried downgrading several libraries but still not achieved to make it work in Ubuntu.

Edit : works on Python 3.8.10

Hi all - We came across the same issue using gensim 3.8.3 and numpy 1.22.2

I removed numpy from requirements.txt (it gets installed as a dependency by other packages anyway) and let pip resolve the dependencies. That fixed the problem for us.

Gensim 3.x is not supported at this point – please upgrade to the latest version (4.1.2 currently). If something doesn't work there, report here. Thanks.

I had the same error on Python 3.8.8 and gensim 4.2.0 on Jupyter Notebook. I fixed by upgrading Numpy to 1.22.4 and restarting run time.

I am on Python 3.10.7, gensim 4.3.1, and Numpy 1.24.1 getting this error when running
import gensim.downloader as api
api.info("text8")

Hi there, I am using poetry, and installing the latest gensim forced a downgrade to numpy 1.26.4 from 2.1.2

This breaks some other things that were expecting numpy 2 (of course it's the other offending package for not properly specifying only numpy 2) but still, should gensim be officially depending on numpy 2 or not?
