Installing in Anaconda

[hmedal]

Hello,

I am trying to install GPFlowOpt in Anaconda. Here is the error I am getting:

Any guidance you can provide is appreciated.

Try pip install git+https://github.com/GPflow/GPflowOpt.git --process-dependency-links to get the dependency

Thank you! Unfortunately, it looks like pip no longer supports --process-dependency-links (https://github.com/pypa/pip/issues/6162).

$ pip install git+https://github.com/GPflow/GPflowOpt.git --process-dependency-links

Usage:   
  pip install [options] <requirement specifier> [package-index-options] ...
  pip install [options] -r <requirements file> [package-index-options] ...
  pip install [options] [-e] <vcs project url> ...
  pip install [options] [-e] <local project path> ...
  pip install [options] <archive url/path> ...

no such option: --process-dependency-links

I am using pip version 19.0.3.

pip 19.0.3 from /anaconda2/envs/gpflowopt/lib/python3.7/site-packages/pip (python 3.7)```

You can install GPFlow 0.5.0 directly from git: https://github.com/GPflow/GPflow/tree/0.5.0

I have faced the same problem. Because pip doesn't support --process-dependency-links at all, I use pip install pip==18.1 to reinstall pip to previous version and it works.

The following instructions worked for me. The instructions assumes that the current directory has both GPflow and GPflowOpt folders (clone them from github if needed).

conda create -n GPflowOpt python=3.5 numpy scipy jupyter matplotlib pip=10
conda activate GPflowOpt
pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.2.1-cp35-cp35m-linux_x86_64.whl
cd GPflow
git checkout tags/0.5.0 -b 0.5.0            # GPFlowOpt requires GPflow=0.5.0
python setup.py install
cd ../GPflowOpt/
pip install -e . --process-dependency-links

These instructions follow from:

1. https://github.com/GPflow/GPflow/blob/ce5ad7ea75687fb0bf178b25f62855fc861eb10f/.travis.yml#L20
2. Older version of pip required for process-dependency-links. pip==18.1 did not work for me.

These instructions allowed me to run the examples

Faced the same issue. I have Python of version 3.8.3. For gpflow a version='>=3.6,<3.7.0a0' is required. Therefore, my solution was as follows:

1. install a venv with the given python version.

2. install GPFlow 0.5.0 directly from git: https://github.com/GPflow/GPflow/tree/0.5.0 check the version before cloning (better to download the 0.5.0 version and use pip install .)

3. Check the insatllation and version. Can face an error like "GPflow-0.5.0\gpflow\session.py", line 8, in AttributeError: module 'tensorflow' has no attribute 'Session'" Solution: in TF 2.0 you should use tf.compat.v1.Session() instead of tf.Session()

4. Then install gpflowopt using "pip install git+git://github.com/GPflow/GPflowOpt.git"

5. Check the insatllation and version. anaconda3\envs\OPT\lib\site-packages\gpflow\session.py", line 8, in class TracerSession(tf.Session) Solution: in TF 2.0 you should use tf.compat.v1.Session() instead of tf.Session()

6. Now it is installed properly.
