compas installation problem

[Voulp]

Hello,

I cannot understand what could I be doing so wrong, but even the simplest compas installation (using conda) is not finishing correctly. I created a new environment in conda ("research") and installed compas there, and I can see it in the Anaconda Navigator (compas 0.19.3), however when I load the environment in the Anaconda prompt and type "python -m compas" I get the following message:

C:\Users\kvoulpio.conda\envs\research\python.exe: No module named compas.main; 'compas' is a package and cannot be directly executed

Moreover, when I go manually into C:\Users\.conda\envs\research I do not see any compas folders/files.

When I try to install the pip way, I get a command error with exit status 1 (see full text below)

Final note: when I load compas in a python terminal (in this case just the Windows cmd prompt) I get this:

import compas compas.version '0.5.0'

I can only think this is from an old installation (I briefly used compas two years ago). I cannot seem to find it anywhere in my system though (am I that stupid?). I have an Admin account on my machine, which has caused problems in the past (double installations etc). However in this case I installed everything on my user profile, so this should not be an issue.

Thank you in advance for advising on this issue. I use Windows 10, Python 3.9.1, and Anaconda 3 (which in turn has installed Python 3.8.6 on its environments.

Just to make sure, does the following work? (From a conda prompt)

conda create --name test --yes
conda activate test
conda install compas
python -m compas

[Voulp]

Hi, Same error (No module named compas.main) However I noticed that upon creating the new environment I load Python 3.9.1 (which already exists in my system). When I installed compas via conda, Python downgraded to 3.8.6. No idea if this could cause issues.

[tetov]

Could you please post the output of these commands

conda activate test
where python
conda list

please?

compas does not support Python 3.9 (yet) which is why anaconda is downgrading the python version in the environment.

[tetov]

I have the exact same packages installed in my test env and I can still get python -m compas to work..

Might also be useful, @Voulp:

conda activate test
conda info

@brgcode @gonzalocasas could you please take a look?

[gonzalocasas]

Could it be you have compas 0.5.0 installed via an older method, like, adding it to the PYTHONPATH (environment variables)?

[tomvanmele]

currently COMPAS is not yet officially available for Python3.9... (there packages on conda-forge are for 3.6, 3.7, 3.8). to avoid the main problem, please do the following and paste the result here

conda activate test
python

>>> import compas
>>> compas.__version__
>>> exit()

also, can you paste here the output of (in the Anaconda Prompt)

echo %PATH%

and, finally, fwiw, the bug in your original post is related to your system Python and not the one installed by conda. make sure to run all conda commands in the Anaconda Prompt and not the Command Prompt...

[Voulp]

Thank you both, I managed to find and delete all the old compas files from my 2019 manual install. Now it seems to work.

Just in case you want to see my %PATH%, here is the result (from the research env)
