This post gives some of the error messages I received, and the actions I took to resolve the problems.

Python builds
Easy fix which no one tells you about (it took me 3 days to find this). Add
import setuptools
to the top of the file.
COLIN:/u/pymqi: >python3 -m build
No module named build.main; ‘build’ is a package and cannot be directly executed
You have a build directory in your project
https://pypi.org/search/?q=build
then install it
python3 setup.py bdist_wheel … error: invalid command ‘bdist_wheel’
I needed “import setuptools” at the top of the setup.py file. I also needed wheel to be installed.

This file was in /u/tmp/python/usr/lpp/IBM/cyp/v3r10/pyz/lib/

CEE3587S A call was made to a function in the AMODE 31 DLL //ADD2 from an AMODE 64 caller.
I was trying to call a C program from Python – but i was built with 31 bit mode – not 64 bit mode.
You need to compile it with LP64, and bind in 64 bit mode, and use //BIND.SYSLIB DD DISP=SHR,DSN=CEE.SCEEBND2
ImportError: CEE3512S An HFS load of module /u/tmp/py/mq.so failed. The system return code was 0000000130; the reason code was 0BDF0
I had a bind error. When I fixed it – it worked.
The IBM documentation says
A package shared library may get tagged incorrectly when using the xlc utility. Verify that the shared library is untagged by running the following line:
ls -alT
If the file is tagged, with the output being similar to the following line:
t ISO8859-1 T=on
you can remove the tag with the following command:
chtag -r <filename.so>
ERROR: Could not install packages due to an EnvironmentError: Erno 111 EDC5111I Permission denied.: ‘/u/.local’

I was trying to install a package using
python3 -m pip install /tmp/… .whl /tmp/… whl –no-cache-dir
It defaults to storing things in /u/.local. I needed
export PYTHONUSERBASE=.

IEW2606S 4B39 MODULE INCORPORATES VERSION 3 PROGRAM OBJECT FEATURES AND CANNOT BE SAVED IN LOAD MODULE FORMAT.
I was trying to save a DLL in a load library.
I had created the PDSE using
//PYTALL JOB 1,MSGCLASS=H
//S1 EXEC PGM=IEFBR14
//DD1 DD DISP=(MOD,DELETE),SPACE=(CYL,(1,10,10)),
// DSN=COLIN.PDSE2

//DD2 DD DISP=(NEW,CATLG),SPACE=(CYL,(1,10,10)),
// DSNTYPE=(LIBRARY,1),
// DSN=COLIN.PDSE2,
// DCB=(RECFM=U,LRECL=0,BLKSIZE=6400)
I was building it in OMVS using
/bin/xlc $name.o -o //’COLIN.PDSE2($name)’
This tried to use data set COLIN.COLIN.PDSE which did not, exist, so it tried to create it, and created a PDS, not a PDSE.
The statement
/bin/xlc $name.o -o “//’COLIN.PDSE2($name)'”
With double quotes around the name worked.

EDC5061I An error occurred when attempting to define a file to the system. (errno2=0xC00B0403)
I got this trying to open a data set from from a Python program.
C00B0403: The filename argument passed to fopen() or freopen() specified dsname syntax. Allocation of a ddname for the dsname was attempted, but failed.
I used
printf(“AMRC\n”);
printHex(stdout,__amrc ,sizeof(__amrc_type));
The first word was 00000210.
Interpreting error reason codes from DYNALLOC gives
210: Meaning: Requested data set unavailable. The data set is allocated to another job and its usage attribute conflicts with this request. (dsname allocation)
I had the dataset open in a ISPF window.
EDC5129I No such file or directory. (errno2=0x05620062)
I was trying to use fopen(“DD:VB”…) where VB was not in the JCL.
When I specified a data set name “//’COLIN/VB'” it worked.
BPXM018I BPXBATCH FAILED BECAUSE SPAWN (BPX1SPN) OF /BIN/LOGIN FAILED WITH RETURN CODE 0000009D REASON CODE
0B1B0473
I got this running under PGM=BPXBATSL. When I changed it to PGM=BPXBATCH it worked.
BPXBATCH
BPXBATCH makes it easy for you to run shell scripts and executable files that reside in z/OS® UNIX files through the MVS™ job control language (JCL)…
In addition to using BPXBATCH, a user who wants to perform a local spawn without being concerned about environment setup (that is, without having to set specific environment variables, which could be overwritten if they are also set in the user’s profile) can use BPXBATSL. BPXBATSL provides users with an alternate entry point into BPXBATCH. It also forces a program to run by using a local spawn instead of fork/exec as BPXBATCH does. These actions allow the program to run faster.
can’t open file ‘//DD:STDIN’: [Errno 92] EDC5092I An I/O abend was trapped.
I was using AOPBATCH, and had PGM=AOPBATCH,PARM=’//usr/lpp/IBM/cyp/v3r8/pyz/bin/python3 //DD:STDIN’
where STDIN was DD *, trying to read from the inline data. Using //STDIN DD PATH=’/u/tmp/zos/z.py’ worked fine.
SyntaxError: Non-UTF-8 code starting with ‘\x83’ in file on line 1, but no encoding declared;
I got this using // PGM=AOPBATCH,PARM=’//usr/lpp/IBM/cyp/v3r8/pyz/bin/python3′ and letting the Python source default to //STDIN. I had to specified
// PGM=AOPBATCH,PARM=’//usr/lpp/IBM/cyp/v3r8/pyz/bin/python3 //DD:STDIN’ for it to work.

// PARM=’pgm /usr/lpp/IBM/cyp/v3r8/pyz/bin/python3 /u/tmp/zos/y.py….’
I also got this trying to run a java program. I needed environment variable _BPX_SPAWN_SCRIPT=YES when using the BPXBATSL utility
to run the command (or a nested command).
FOPEN: EDC5129I No such file or directory. (errno2=0x05620062)
If you try to use fopen(“DD:xxxx”…) from a shell script (or BPXBATCH PARM=”pgm… ” you will get
FOPEN: EDC5129I No such file or directory. (errno2=0x05620062)
If you use fopen(“//’COLIN.VB’”…) and specify a fully qualified dataset name if will work.
fopen(“//VB”..) will put the RACF userid in front of the name. For example attempt to open “//’COLIN.VB.’”

I put some debug code in, and found it was trying to find dateutil-zoneinfo.tar.gz.
I tried installing various packages. Finally the following worked for me
pip uninstall python-dateutil
pip install python-dateutil

Successfully installed python-dateutil-2.9.0.post0
pip install tzdata

Successfully installed tzdata-2025.3
and it worked.
ModuleNotFoundError: No module named
My code was
import dumphex
... dumphex.dumphex()
and I got the message
ModuleNotFoundError: No module named ‘dumphex’
This was strange because the dumphex.py was in the same directory as the main python code.
Solution
It needs
from . import dumphex
