Re: [ferret_users] error in student_t_cutoff function

[saurabh rathore <rohitsrb2020@xxxxxxxxx>]

Dear Karl and Ryo

G'day

Thank you for your help the problem is sorted out from your suggestions. I would like to write the procedure for this for others as well.

$ conda env list    !! it will show all the environment in your system !!!

FERRET                *  /home/srathore/anaconda3/envs/FERRET     !! this is my ferret env path !!

$ conda activate FERRET     !! to activate FERRET env !!

$ vi .bashrc   

open the bash script and go to the end of the script as shown in the attached image and in the end of the file add the line path/of/your/FERRET-env/lib/python3.7/site-packages/pyferret depend on the path of your env (mine is /home/srathore/anaconda3/envs/FERRET) !!

save the file and close it.

now you can check the function

$ conda activate FERRET

(FERRET)$ pyferret -nojnl

yes? sh func student*

it will show you....

STUDENT_T_CUTOFF(P,nf)
    Return student-t cutoff
    P: Confidence Limit
    nf: nf (Number in sample)

cheers, saurabh

I appears the conda installation on Linux is not defining LD_LIBRARY_PATH so that the libpyferret library can be found.  (At least this is the case with my miniconda-python3 installation on RHEL7.)  If you defined the environment variable LD_LIBRARY_PATH to be the directory containing the libpyferret .so library then all works fine.

So in the bash shell:

    export LD_LIBRARY_PATH=/path/to/conda/envs/FERRET/lib/python3.7/site-packages/pyferret

Dear Ryo,

G'day

this is my anaconda installation and ferret installation environment:-

base                  *  /home/srathore/anaconda3
FERRET               /home/srathore/anaconda3/envs/FERRET

This is the error message that I am getting on using external function:-

**ERROR in External Function student_t_cutoff:
  Dynamic linking call dlopen() returns --
  "libpyferret.cpython-37m-x86_64-linux-gnu.so: cannot open shared object file: No such file or directory".

this is the the file in the error message which I can see after applying your suggestion. So it seems it is there but not able to open:-

./pkgs/pyferret-7.5.0-py37ha0fb077_1/lib/python3.7/site-packages/pyferret/libpyferret.cpython-37m-x86_64-linux-gnu.so

Did I mess up with the installation procedure?

Dear Ryo,

Thank you for your reply. I would like to mention the installation process. 

1) first I installed Anaconda

2) then I created an environment named FERRET 

3) then I installed ferret in this environment

So if I am correct my anaconda installed in /use/local

But my Ferret is installed in the environment called FERRET rather then base. 

I don't know that is my installation is having any problem?

Cheers Saurabh

The error message "No such file or directory" suggests either 1) that the search path doesn't include the directory where the pyferret libraries reside or 2) that the library doesn't exist.

To check (1), what do you find from this command?

yes? SPAWN env | grep -i ferret

To check (2), go to your anaconda directory.  (I don't know where yours is, but mine is under /usr/local/ .)  Then, do this

$ find . -iname '*pyferret*'

I find the library, which is  /usr/local/miniconda3/envs/FERRET/lib/python3.6/site-packages/pyferret/libpyferret.cpython-36m-darwin.so  .

Cheers,

Ryo
