Fail to install pymc in Anaconda on mac OS #174

Closed ottiP closed 6 years ago

ottiP commented 6 years ago

When I try to install pymc through anaconda:

conda install pymc

I obtain the following error:

Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict: - blaze - pymc Use "conda info " to see the dependencies for each package.

How can I fix it?

Thank you in advance for your help

What were the conflicting dependencies? We are preparing a new release now, so we would like to make sure there are no conflicts. In the meantime, feel free to use pip, which should not have issues.

Hi Chris, Thank you for your email. So I am quite struggling because it seems that blaze is in conflict with installing pymc (as you can see from the error message). I have tried to use pip as well but when I try to launch it on juputer notebook it fails. Do you need further details? Thank you, Ottavia

Ottavia,

There are now new builds of PyMC (version 2.3.7rc1) on conda. Can you try installing from conda again? If it fails, please send along the entire message (and the output from conda info).

fonnesbeck commented 6 years ago

@ottiP also, are you intending to install the older version of PyMC? Or did you mean to install PyMC3 (the newer project). If so, you want to do:

conda install pymc3

(note the 3 in the name)

ottiP commented 6 years ago

Hi Chris, So here are the updates:

  1. I tried to install pymc 2.3.7 following the instructions on conda: conda install -c conda-forge pymc

The installation was successful although when I tried to run pymc on my notebook some issues occurred:

ImportError: dlopen(/anaconda2/lib/python2.7/site-packages/pymc/flib.so, 2): Library not loaded: @rpath/libopenblas.dylib Referenced from: /anaconda2/lib/python2.7/site-packages/pymc/flib.so Reason: image not found

I will load the screenshot of the output from conda info.

  1. I have then tried to install pymc3 and everything went fine. It seems working although the notebook I am following for my studies is written in pymc and it doesn’t seem natural to move from one library to the other.

I am sorry to bother you further.

Ottavia

OK, thanks for the report. It looks like there is an issue with the 2.3.7 package cc @kyleabeauchamp

Yes, if you already have models written in PyMC2, then you would need 2.3.7; they will not automatically run under PyMC3. We will get it working.

Are you running on Windows, Linux or Mac?

ottiP commented 6 years ago

Thank you very much!!

I think I've figured it out. Can you try conda install openblas in your environment? I think we need to add openblas to the requirements.

ottiP commented 6 years ago

It works!!! :)

Thank you very much for your help!
