Issue installing newest version (cython problem?)

[murphytho]

Hi there,

I just wanted to join the ranks of others having issues with the current github build. My code/error is below. I have had Telescope installed in the past, but am on a new machine and am struggling to get it up and running.

I couldn't get around the numpy error on the bioconda distribution, but I'm also having trouble installing from github with pip.

Here is the error:

My guess is that it's a cython compatibility issue, but rolling back to a previous version of cython did not help.

I should also not that I had issues setting up the environment from the yml github link, so I had to download it locally and set it up from there. Others have noted the same issue, such as can be seen here

Any update on this? It's proven challenging to circumvent this issue. Can the devs just at least push the newest version to Bioconda? The current release still has the np.int incompatibility that was fixed on the latest github version.

[murphytho]

I actually figured out a couple ways to get it to work eventually. One was installing the bioconda version and fixing the numpy error. I didn't write down how I did it but I want to say I rolled back the version of python the environment was using? Something along those lines.

The other way I got it to work was installing from the sc_remove commit straight from GitHub. This is technically the most updated version, I think. I would definitely try this first before screwing with numpy-- I remember that being a pain.

Still would be nice to have a real fix, but in the meantime, I got this to work.

[adamspierer]

Thanks @murphytho for the pointer and agreeing with the request for an official fix. That said, I was able to get the test to work after a while of massaging and figured I would pay it forward.

My first issue is that I couldn't get past the beginning of the tutorial because conda (which I use) and mamba (used in the tutorial) don't play well together. So I created a conda virtual environment from the environment.yml file and then switched to that environment:

conda env create -n telescope --file=environment.yml
conda activate telescope

Then, I took the hint from above comment and did some work to make the sc_remove branch the main one:

## Sync repos
git fetch

## Switch to main branch
git checkout main

## Merge local main branch with sc_remove branch on github
git merge remotes/origin/sc_remove

I executed the test command in the tutorial:

eval $(telescope test)

But this gave me an error message that comes from using a depreciated file read mode:

File "/mnt/nimble/home/aspierer/miniconda3/envs/telescope/lib/python3.12/site-packages/telescope_ngs-1.0.3+49.g2832514-py3.12-linux-x86_64.egg/telescope/utils/_annotation_intervaltree.py", line 37, in __init__
    fh = open(gtf_file,'rU') if isinstance(gtf_file,str) else gtf_file
         ^^^^^^^^^^^^^^^^^^^
ValueError: invalid mode: 'rU'

I fixed this by using nano to edit the mode from 'rU' to 'r':

    fh = open(gtf_file,'r') if isinstance(gtf_file,str) else gtf_file

I ran the test command above once more and got the output I was promised (Final log-likelihood of 95252.596293 and two tsv files).

Hopefully the last few hours of troubleshooting can save others in the future.

I managed to install telescope without modifying any code. Just using a custom environment.yml file with the correct versions of the packages solved the problem.
This is the environment.yml:

name: telescope
channels:
  - conda-forge
  - bioconda
  - defaults
dependencies:
  - python=3.7
  - future
  - pip
  - pyyaml
  - cython
  - numpy=1.21
  - scipy
  - pysam=0.19
  - htslib
  - intervaltree
  - pandas
  - samtools
  - openssl=1.1

Then, create the environment:
conda env create -n telescope --file=environment.yml

Activate the environment:
conda activate telescope

And install the last version of telescope:
pip install git+https://github.com/mlbendall/telescope.git

The test command worked perfectly.

@tmontserrat hi, I ran your .yml also, but didn't work. Shows the same Cython error. Can you guide me on how to resolve the installation issue?

[marcos-da-conceicao]

I was able to get the Telescope to work using the following codes:

First, I created an environment with the following dependencies:
conda create -n telescope_env python=3.6 future pyyaml cython=0.29.7 numpy=1.16.3 pandas=1.1.3 scipy=1.2.1 pysam=0.15.2 htslib=1.9 intervaltree=3.0.2

Then I tried to install the latest version with bioconda and conda-forge already installed:
pip install git+https://github.com/mlbendall/telescope.git

And that's it.
