Windows installations fail

[folterj]

All Windows installations as described appear to fail for me.
OS: Windows 10 64-bit
Python: 3.x 64-bit
GPU: Nvidia GTX 1050 Ti

I've tried the approaches as documented without success:

• The easy way (tensorflow with and without -gpu)
• Using Beta Installers
• Installing via Conda (/pip)
• Compile it yourself
  • creating a local conda channel, and installing from there
  • running CMake/build manually with customized options

The main error appears to be that a suitable version of tensorflow cannot be found.
As a side note, according to the tensorflow documentation, Windows GPU is supported up to TF version 2.10, is currently preferred installed via PIP, not using the 'tensorflow-gpu' package as the regular package automatically detects GPU. I have been able to install tensorflow (and pytorch) separately with GPU support.
Installing tensorflow separately before installing TREX, results in TREX unable to find tensorflow, even if the expected version is installed (2.8). I've attempted installing various versions of Python 3 (all 64 bit) and tensorflow (with and without -gpu).
The Windows beta installer fails on env/version conflicts (see attached file install.log).
For completeness (though this is my least favourite method), the compile using CMake approach fails as bellow (I note it appears to use python 3.12):

  test_python.cpp
C:\Users\Y\PycharmProjects\trex\Application\build\_deps\pybind11-src\include\pybind11\detail\type_cas
ter_base.h(482,21): error C2027: use of undefined type '_frame' [C:\Users\Y\PycharmProjects\trex\Appl
ication\build\src\commons\examples\test_python.vcxproj]
  (compiling source file '../../../../src/commons/examples/test_python.cpp')
  C:\Program Files\Python312\include\pytypedefs.h(22,16):
  see declaration of '_frame'

Another note is that the python and tensorflow versions do not appear to be pinned in the configurations.

I'm running into the same issue, just to confirm that it indeed is an issue.

[mooch443]

Hey, I assume this is to be expected - did you try the normal versions first? Or what is your use case?

I have deleted the beta installers since they weren't supposed to be fully public yet - I had just given them to some people and they become outdated pretty quickly :-) I assume they all fail, although I haven't tested in a while.

[roaldarbol]

Hey! The issue is that the normal version doesn't install, I think that's why we've both tried using the beta installer too. Here's the log from right now, trying a few different ways to install the non-beta, first with tensorflow-gpu which is the one showing on trex.run:

Hey @mooch443! Just to prioritise my tracking in the coming weeks - do you reckon you will have time to look at/sort this one out? I still have the option of running the tracking on my Mac, but it's also my writing/analysis workhorse, so will take me longer to get through the tracking (it then runs nights only). :-)

[mooch443]

conda create -n trex_normal -c trexing trex tensorflow-gpu numpy=1.23.1
this works for me. in general the trouble seems to be that the available software in conda repositories has evolved, but unfortunately i hadn't specified the exact numpy version in this older version of the software. specifying 1.23.1 worked for me (on windows).

Ah, I think I found the issue!
How have you installed conda @mooch443 - with Anaconda? When you create a conda env, does it use a different channel by default? I think if you've installed conda with Anaconda, the default channel is anaconda, whereas installed with miniforge, the default is conda-forge.
Now it seems that tensorflow-gpu is on anaconda, bu NOT on conda-forge, which could explain the discrepancies. So maybe we should be more explicit and add the anaconda channel into the one-liner to ensure it works across all conda installations.

This works for me:

conda create -n trexenv -c trexing -c anaconda trex tensorflow-gpu

(and much much faster solving by using pixi)

So seems like numpy may not have been the culprit after all 👍

[mooch443]

What version of conda do you have? Maybe you should update that? Because in newer versions of conda you'll get a summary of the current channels being used before the error messages. And it still works for me with the exact command. So within the base environment I recommend doing:

conda update --override-channels -c defaults --all

This is good practice anyway. They may change how information is retrieved from channels in new versions. Make sure it actually updates something and then try again. You can also try adding the defaults to the previous command:

conda create -n trex_normal --override-channels -c trexing -c defaults trex tensorflow-gpu numpy=1.23.1

This is just "conda debugging", which is the most boring part of software development. I just merged my current version into the main dev branch btw, trying to find the last couple missing pieces ;) Looking forward to adding actual new features afterward. You can try this, but you might get a version thats bugged depending on when you download:

# windows or linux
conda create -n betarex --override-channels -c trex-beta -c pytorch -c nvidia -c defaults trex

No I have not installed Anaconda - I am using miniconda, so its just the main/defaults channel. But the solution is to override-channels as in my previous message then. Also updating conda might be a good idea, and getting rid of the anaconda part. Nobody needs the GUI :-D

This works for me:

conda create -n trexenv -c trexing -c anaconda trex tensorflow-gpu

This seems wrong. Can you try my command I suggested above (after updating)?

[roaldarbol]

What is it precisely you dislike about the solution I used? I'm not sure I like the idea about using defaults channel as that seems to vary between installations, and it's terribly implicit - even when I can now see which channels are being used, I have no idea which channel repository is being used as default (you may know this much better than me, am I understanding this correctly?)

I ran the updating, now none of the solutions work anymore:

When I follow along in the pkgs folder during the installation, tensorflow-base-2.6.0 is being created, but then it suddenly disappears - no clue why. I'm continuing to try some debugging. (Still works with pixi without any issues).

I think no matter what, it would be good to add a section to the docs about this sort of issue with some general things to attempt. Conda channels is a black box to lots of folks, so having some things to try is good I think.

Oh, you're changing from Tensorflow to PyTorch in the new version?! AMAZING!!! So many headaches from that stuff! (that installation works just fine!)

[mooch443]

I see, you should clean your caches then I reckon. conda clean -a could do the trick - but this is probably just because you haven't done this in a while / they did something illegal, like uploading under the same name?

In any case, as far as I understand defaults is a combination of the largest and best maintained channels. It is a specific set of channels, not just anaconda or whatever is your "default" setting. I cannot find specific documentation on that, but afaik it includes main (https://anaconda.org/main), r and free. The output you provided seems to suggest that it works as intended. Just that the packages in your cache are broken.

[mooch443]

I am using both in fact. Not an easy feat. I would like to port all the previous code to pytorch, but why change a running system. The difference is installing it via pip instead of conda (this process is hidden to the end user). It also means you have to use a fix numpy version.

Absolutely right, I've never done that in fact! Didn't even know that was a thing. However, the issue remains the same afterwards. Maybe tensorflow-base-2.6.0-gpu is being overridden by tensorflow-gpu?

EDIT: Installing without tensorflow-gpu works, then subsequently installing tensorflow-gpu reveals that it modifies some of the dependencies. I can't quite figure out what's going on, and unfortunately don't have more time for debugging today, but can try again tomorrow. Here's the output of attempting to install tensorflow-gpu afterwards:

In any case, as far as I understand defaults is a combination of the largest and best maintained channels. It is a specific set of channels, not just anaconda or whatever is your "default" setting. I cannot find specific documentation on that, but afaik it includes main (https://anaconda.org/main), r and free. The output you provided seems to suggest that it works as intended. Just that the packages in your cache are broken.

I think at least the r channel is no longer getting support - I can't remember where I read it, but it also seems the packages are no longer being updated there. I think it just confuses having implicit channels. It's also one of the reasons prefix-dev (who developed mamba and now pixi) have decided on only having explicit channel names. In pixi they default to conda-forge I think, but every channel has to be named.

Just reiterating, I think some of this information would be really good to place in docs - maybe have a Troubleshooting section inside of Installation.

(trex_normal_2) C:>conda install tensorflow-gpu
Channels:

• conda-forge
• defaults
• trexing

As you can see, conda-forge is injected here again. This is the reason it tries some weird stuff. You shouldn't mix main/conda-forge channels, this usually breaks stuff!

Regarding the tensorflow-gpu, maybe there is generally some stuff going on with your channels. If you can, reinstall conda and use miniconda - or just install an additional miniconda on your system in a different location. I suspect this might resolve issues.

I also think this is mainly a conda issue right now, but if there will be similar issues with the new version then I'll add them.

Okay, I was just mentioning that for completeness. The r channel does not really do anything here. I compiled the software using the defaults channels, so if you switch to conda-forge when installing it - even if you get the packages that it wants and it installs "successfully" - it won't work properly in my experience. On Windows it might be more tolerant, but on Linux you won't get it working at all in fact.

This env was installed with your line, so it's injecting conda-forge even with override-channels. And conda-forge is not part of my defaults:

(base) C:\WINDOWS\system32>conda config --show default_channels
default_channels:
  - https://repo.anaconda.com/pkgs/main
  - https://repo.anaconda.com/pkgs/r
  - https://repo.anaconda.com/pkgs/msys2

But even when conda-forge is not included, the result is the same:

(base) C:\WINDOWS\system32>conda create -n trex_normal --override-channels -c trexing -c defaults trex numpy=1.23.1
